Speeding up your internet connection under Linux and Windows

(Setting up DNS caching)

1 Good old dry theory

1.1 Introduction

The internet is going thru an evolution, faster pc's, more reliable connections etc... But the greatest evolution are the capacity of the lines. What where telephone line are now ISDN lines or cable modems. But there are still people (unfortunate people like me) who have such a sloppy telephone line, which is sloooooow. So people are beginning to search ways to speed up their connection. Their are tools like download managers, tools that download the underlying pages of a visited web site in idle times. And so there are many ways that go to adjusting the hardware of your modem. Like you all see the software is either Windows based or lets you fuck up your hardware. This way is for Linux and is so easy a Windows user could do it :P
There is also an explanation on how to do the exact same thing under Windows

1.2 Who should be reading this document, requirements

Everyone who wants to speed up their (modem) dial-up account by some seconds. And want to do this in five minutes (if not less). Before asking any questions, please make sure you have read at least the basic networking tutorials at blacksun.box.sk.
If you still have questions regarding this tutorial, please make sure you've already read at least some of the basic networking tutorials at blacksun.box.sk. Also, please do not Email any member of BSRF directly. There is a message board at blacksun.box.sk - use it.
Information on how to do the same thing under Windows can be found at the bottom of the tutorial.
Requirements

• A computer
• A dial-up connection to the internet
• Linux up and running
• Named installed (1)
• 5 minutes of time
• Some spare change for me (*grin*)

(1) Named is a the nameserver package, this is standard and the most commone Linux distrubution and should bring no problems while installing

1.3 What does a nameserver do?

What does a nameserver do ? Well, suppose you are dialed in with you ISP and you wish to go to www.xxxxx.com. You open up you browser and type in the URL box http://www.xxxxx.com, you press enter and wait until xxxxx appears.
Simple, isn't it ? Let's look behind the scenes to find out what's really going on in here.

1. Your computer gets the request to connect to www.xxxxx.com, but what is www.xxxxx.com ? Well it the alias of a computer (which has an ip) and has an httpd daemon running (on port 80).
2. Your computers checks if that site isn't running on your own computer or on you local network. So it checks your /etc/hosts file (which has you local intranet information) or it checks a local nameserver (but because you're reading this I guess you don't have a nameserver installed (yet) so that won't be the case). By the way, this is a good chance to mention that DNS stands for Domain Name server.
3. In fact your computer doesn't check if www.xxxxx.com is on your local network, it checks if it can find the ip of www.xxxxx.com on you local intranet. (You 'might' have heard once that the entire internet is tcp/ip based :P)
4. Then your computer checks the file /etc/resolv.conf file should look like this.
   nameserver 123.123.123.123
   
5. This is the nameserver of you ISP. And when nothing can be found on the local intranet you computer will query this nameserver. (if this nameserver is unreachable the you'll get an error).
6. When this nameserver is reachable it will answer with an ip. If www.xxxxx.com is unknown to the nameserver it will query some other nameserver. But in the end you'll get your ip.
7. Once this ip (lets say 123.123.123.111) is known there will be tried to establish a connection to 123.123.123.111:80 (this connection will be made by the standard routing procedure as can be viewed by typing route from a root shell.

Now the communication will be established, files will be transferd using the http protocol. So the nameserver simply translates www.xxxxx.com into an ip by quering its own databases or querying other databases.

1.4 Whooow that sounds very cool !!! So ? :p

Well suppose those seven steps take about 2 seconds (if you have a speedy connection and your ISP has a nameserver with almost no network traffic and if the ip is in the nameservers cache). So if this was an utopia it would take two seconds. So in these times it'll take a bit longer. In this tutorial we'll make something called 'a caching only nameserver'.

1.5 What is a caching only nameserver

Well, this is a special 'type' of nameserver. This is not intended to be the nameserver of your intranet. The only thing it does is to cache all names and ip's that are queried from the local network. The first time you query an ip, an other database has to be queried (isp). But any other time that query does not have to find place. It is on you own hard disk, so it doesn't consume any bandwidth, and site will come up some seconds faster on your screen which makes surfing a lot more FUN. You can say now what the hell are two seconds? Yes but how often do you go to a search engine ? How often do you go to you favorite site and further, how often doe you check your e-mail ? (once every 10 minutes is a Netscape default) Here ends the theory, now you should be able to understand what a caching only nameserver does and how it can speed up you connection with a few seconds, now go ahead and type something.

2 Fuck that damned theory, let me type something

2.1 named.conf

First we edit the general config file of the nameserver. The file is called /etc/named.conf and it should look like:

options {
        directory "/var/named";
        /* Some shit */
};
....

This first part of the file is the one that needs changes. For this you need to know the nameserver of your ISP (NOT the name but the IP !!!), you change the file to:

options {
        directory "/var/named";
        forwarders {
                123.123.123.123;
                123.123.123.124;
                };
};
....

You've now simple said that an unknown query has to be forwarded to the ip's above. If the first is not reachable the second one will be tried.

2.2 Changing the nameserver

In fact you have now an up and (almost) running nameserver. There is just one little detail you have to take care of, that's the fact that your computer doesn't recognize / will use you nameserver yet. You have to edit /etc/resolv.conf . And you should edit the file so it'll look like:

# nameserver 321.321.321.321
nameserver 127.0.0.1

The first line was your original nameserver, just comment this (you never know ...) and then you add the line nameserver 127.0.0.1 this just says that queries no longer have to be forwarded but can be answered by you OWN local nameserver.

2.3 Up and running

Now you just have to (re)start your nameserver with killall -HUP named . Then you check you logs ( /var/log/messages ) and hope they'll look like

Nov 20 13:29:34 SaTaN named[692]: starting.  named 8.2.1 Fri Sep 24 14:52:24 EDT 1999 ^Iroot@porky.devel.redhat.com:/usr/src/bs/BUILD/bind-8.2.1/src/bin/named

If you see a last line, like mine, don't worry about it. It means you are not yet connected to the internet. When you get some erros, it means that you have not edited you config file properly so you have check it again. (hint: check if all the ; are in place and every { is closed with an } )

2.4 U don't believe me ?

Ok, for everyone who doesn't believe me ...

[root@SaTaN /] nslookup www.iwanttoquerythis.com
Server: localhost
Address: 127.0.0.1

Name: www.iwanttoquerythis.com
Address: 123.123.123.321 ... other ip's ..
Aliases: If available ...

This was the first query and a request was sent to the nameserver mentioned in the config file. For this far you know you nameserver can forward addresses :p it's a start.

[root@SaTaN /] nslookup www.iwanttoquerythis.com
Server: localhost
Address: 127.0.0.1

NON-AUTHORITIVE ANSWER
Name: www.iwanttoquerythis.com
Address: 123.123.123.321
Aliases: ...

Cool, it says Non-authoritive answer. What does it means ? Well, it just wants to say that for that answer there was no need to forward the request, cool huh ?

2.5 And here's another way to do it

You can also manage your local DNS database by yourself! Simply add lines to the /etc/hosts file that will look like this:
IP-address hostname #comment
For example:
1.2.3.4 www.some-website.com #just another stupid website
In case you're wondering, you don't HAVE to put a comment... :p
Oh, by the way, this method is inferior because you have to enter IPs and hostnames by yourself... ouch...

2.6 Local DNS cache under Windows

Hello, poor Windows users. Want to make yourself a nice local DNS cache? Too bad, 'cause you can only use the method described in chapter 2.5, only you will be using c:\windows\hosts (not to be confused with c:\windows\hosts.sam, which is a sample file for c:\windows\hosts) instead of /etc/hosts. If you don't wanna do this manually, you could try and find a program called FastNet, which will scan your browser's bookmarks and history database and automatically add every URL you visit to this database, and will also let you add entries manually.

3 The end

Make A Autorun File For Ur CD Or DVD

If you wanna make a autorun file for that CD you are ready to burn just read this...

1) You open notepad

2) now you writ: [autorun]

OPEN=INSTALL\Setup_filename.EXE

ICON=INSTALL\Setup_filename.EXE

Now save it but not as a .txt file but as a .inf file.

But remember! The "Setup_filename.EXE" MUST be replaced 

with the name of the setup file. And you also need to rember that 

it is not all of the setup files there are called '.exe but some are 

called '.msi

3) Now burn your CD with the autorun .inf file included.

4) Now set the CD in you CD drive and wait for the autorun to begin or if nothing happens just double-click on the CD drive in "This Computer"

How to Reset your lost Bios Password

Reset your lost Bios Password

Here's a DOS trick for Windows 9x, that will reset (delete) your motherboard's BIOS password (aka CMOS password) without any need to open up your computer to remove the battery or mess with jumpers.

This method can come in very handy in the event you ever lose and forget your BIOS password or if you acquire used computers where the unknown previous owners had BIOS passwords set (in fact, this happened to me long ago—I was given a used computer, but there was no way I could enter the CMOS to make changes). It's important to note here that the password we are talking about is only the one that prevents a user from entering the BIOS setup at bootup, not the one that stops you from getting past the boot.

Normally, at bootup you can press a key (usually the DEL key) to access your BIOS allowing you to view it or make changes. With a password set, there is no way to enter setup. Though a password can provide a basic and very effective level of PC security, losing it can be a real headache if you don't know how to fix the problem.

The MS-DOS command that will makes this trick possible is the DEBUG command (debug itself is a utility—debug.exe—which is located in your Windows Command folder). This is not a command to be taken lightly—in other words, it's not a command to play with! You can cause serious corruption with this command and can end up not being able to even boot your computer! Debug is used to work with binary and executable files and allows you to alter (hex edit) the contents of a file or CPU register right down to the binary and byte level.

To begin debug mode, type debug at a MS-DOS prompt or you can specify a file, i.e., DEBUG FILE.EXE. There is a difference in screen output between the two methods. When you type DEBUG alone, debug responds with a hyphen (-) prompt waiting for you to enter commands. The second method, with a file specified, loads the file into memory and you type all the commands on the line used to start debug. In this tip, we will be writing to the BIOS, so the first method is the one that would be used. All debug commands can be aborted at any time by pressing CTRL/C.

Accessing BIOS with DEBUG

The basic trick will be to fool the BIOS into thinking there is a checksum error, in which case it resets itself, including the password. This is done by invalidating the CMOS and to do that we must know how to access the BIOS and where the checksum value of the CMOS is located so that we can change it. Access to the the BIOS content is via what are known as CMOS Ports and it's Port 70 and 71 that will give us the needed access. On almost all AT motherboards, the checksum is located at hexadecimal address 2e and 2f and filling the address 2e with ff is all you should have to do to invalidate the checksum.

Here's what to do if you ever need to reset the password and have no other method, and you don't want to open up your computer to remove the battery or jumpers.

Note! Do this at your own risk. I can only tell you that it has worked for me more than once and has worked for others as well. But I cannot make any guarantees. When I did this, I took a willing risk. The BIOS was Award Modular BIOS v4.51PG

Restart your computer in MS-DOS mode.

When you get to the C:\> or C:\WINDOWS> prompt, type DEBUG and press Enter.

A hyphen (-) prompt will appear waiting for you to enter commands.

Enter the following commands, pressing Enter after each one. Note: the o is the letter o and stands for OUTPUT.

o 70 2e

o 71 ff

q

After the q command (which stands for QUIT), enter Exit.

Then try to enter your BIOS at bootup. The password prompt should now be gone and you should now have full access to it again. However, you will now be at the default BIOS setttings and may want to change them to your preference. You may also want to have your drives autodetected again.

In closing, I should state that in the case of a lost BIOS password, your first step should always be to contact your manufacturer to see if a backdoor password is available that will allow you to bypass the forgotten password.

There are many sites on the net that list backdoor passwords you can try, but beware that some BIOS that are set up to lock up if you enter the wrong password more than a certain number of times, usually only 3 times!

How to make a computer faster

Speed up your PC

1. Remove spyware, and help protect your computer from viruses
Spyware collects personal information without letting you know and without asking for permission. From the websites you visit to user names and passwords, spyware can put you and your confidential information at risk. In addition to privacy concerns, spyware can hamper your computer's performance. To combat spyware, you might want to consider using the PC safety scan from Windows Live OneCare. This scan is a free service that helps check for and remove viruses.
Download Microsoft Security Essentials for free to help guard your system in the future from viruses, spyware, adware, and other malicious software (also known as malware). Microsoft Security Essentials acts as a spyware removal tool and includes automatic updates to help keep your system protected from emerging threats.
The Microsoft Windows Malicious Software Removal Tool is another utility that checks computers running Windows 7, Windows Vista, Windows XP, Windows 2000, and Windows Server 2003 for infections by specific, prevalent malicious software, including Blaster, Sasser, and Mydoom, and helps remove any infection found.
2. Free up disk space
The Disk Cleanup tool helps you to free up space on your hard disk to improve the performance of your computer. The tool identifies files that you can safely delete and then enables you to choose whether you want to delete some or all of the identified files.
Use Disk Cleanup to:

---

Remove temporary Internet files.
Delete downloaded program files, such as Microsoft ActiveX controls and Java applets.
Empty the Recycle Bin.
Remove Windows temporary files, such as error reports.
Delete optional Windows components that you don't use.
Delete installed programs that you no longer use.
Remove unused restore points and shadow copies from System Restore.
Tip: Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.
To use Disk Cleanup:

Windows 7 users

Windows Vista users

Windows XP users

3. Speed up access to data
Disk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk as a file is opened (to piece it back together). The response time can be significantly longer.
Disk Defragmenter (sometimes shortened to Defrag by users) is a Windows utility that consolidates fragmented files and folders on your computer's hard disk so that each occupies a single space on the disk. With your files stored neatly end to end, without fragmentation, reading and writing to the disk speeds up.
When to run Disk Defragmenter
In addition to running Disk Defragmenter at regular intervals (weekly is optimal), there are other times you should run it, too, such as when:

---

You add a large number of files.
Your free disk space totals 15 percent or less.
You install new programs or a new version of the Windows operating system.
To use Disk Defragmenter:

Windows 7 users

Windows Vista users

Windows XP users

Running Disk Cleanup and Disk Defragmenter on a regular basis is a proven way to help keep your computer running quickly and efficiently. If you'd like to learn how to schedule these tools and others to run automatically, please read Speed up your PC: Automate your computer maintenance schedule.
4. Detect and repair disk errors
In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.
As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult or even impossible. The Error Checking utility scans the hard drive for bad sectors and scans for file system errors to see whether certain files or folders are misplaced.
If you use your computer daily, you should run this utility once a week to help prevent data loss.

Run the Error Checking utility:

5. Learn about ReadyBoost
If you're using Windows 7 or Windows Vista, you can use ReadyBoost to speed up your system. A new concept in adding memory to a system, it allows you to use non-volatile flash memory—like a USB flash drive or a memory card—to improve performance without having to add additional memory.

10 reasons why PCs crash U must Know

Why PCs crash

Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications."

You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?

1 Hardware conflict

The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.

For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.

If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:

* Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.

Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.

Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).

When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.

To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.

2 Bad Ram

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.

But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.

One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.

Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.

EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.

3 BIOS settings

Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.

Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to.

A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.

Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).

After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. Go to

* Start-Programs-Accessories-System Tools-Disk Defragmenter

This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.

The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).

Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimisation. This can be adjusted by going to

* Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.

Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.

Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. Go to

* Start-Programs-Accessories-System Tools-ScanDisk

Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.

5 Fatal OE exceptions and VXD errors

Fatal OE exception errors and VXD errors are often caused by video card problems.

These can often be resolved easily by reducing the resolution of the video display. Go to

* Start-Settings-Control Panel-Display-Settings

Here you should slide the screen area bar to the left. Take a look at the colour settings on the left of that window. For most desktops, high colour 16-bit depth is adequate.

If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a hardware conflict. Go to

* Start-Settings-Control Panel-System-Device Manager

Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue) and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts.

If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse.

The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.

Another useful way to resolve video problems is to go to

* Start-Settings-Control Panel-System-Performance-Graphics

Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a device).

Look up your video card's manufacturer on the internet and search for the most recent drivers for it.

6 Viruses

Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk. Go to

* Start-Settings-Control Panel-Add/Remove Programs

Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.

A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.

An excellent antivirus programme is McAfee VirusScan by Network Associates ( www.nai.com). Another is Norton AntiVirus 2000, made by Symantec ( www.symantec.com).

7 Printers

The action of sending a document to print creates a bigger file, often called a postscript file.

Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer's performance.

If the printer is trying to print unusual characters, these might not be recognised, and can crash the computer. Sometimes printers will not recover from a crash because of confusion in the buffer. A good way to clear the buffer is to unplug the printer for ten seconds. Booting up from a powerless state, also called a cold boot, will restore the printer's default settings and you may be able to carry on.

8 Software

A common cause of computer crash is faulty or badly-installed software. Often the problem can be cured by uninstalling the software and then reinstalling it. Use Norton Uninstall or Uninstall Shield to remove an application from your system properly. This will also remove references to the programme in the System Registry and leaves the way clear for a completely fresh copy.

The System Registry can be corrupted by old references to obsolete software that you thought was uninstalled. Use Reg Cleaner by Jouni Vuorio to clean up the System Registry and remove obsolete entries. It works on Windows 95, Windows 98, Windows 98 SE (Second Edition), Windows Millennium Edition (ME), NT4 and Windows 2000.

Read the instructions and use it carefully so you don't do permanent damage to the Registry. If the Registry is damaged you will have to reinstall your operating system. Reg Cleaner can be obtained from www.jv16.org

Often a Windows problem can be resolved by entering Safe Mode. This can be done during start-up. When you see the message "Starting Windows" press F4. This should take you into Safe Mode.

Safe Mode loads a minimum of drivers. It allows you to find and fix problems that prevent Windows from loading properly.

Sometimes installing Windows is difficult because of unsuitable BIOS settings. If you keep getting SUWIN error messages (Windows setup) during the Windows installation, then try entering the BIOS and disabling the CPU internal cache. Try to disable the Level 2 (L2) cache if that doesn't work.

Remember to restore all the BIOS settings back to their former settings following installation.

9 Overheating

Central processing units (CPUs) are usually equipped with fans to keep them cool. If the fan fails or if the CPU gets old it may start to overheat and generate a particular kind of error called a kernel error. This is a common problem in chips that have been overclocked to operate at higher speeds than they are supposed to.

One remedy is to get a bigger better fan and install it on top of the CPU. Specialist cooling fans/heatsinks are available from www.computernerd.com or www.coolit.com

CPU problems can often be fixed by disabling the CPU internal cache in the BIOS. This will make the machine run more slowly, but it should also be more stable.

10 Power supply problems

With all the new construction going on around the country the steady supply of electricity has become disrupted. A power surge or spike can crash a computer as easily as a power cut.

If this has become a nuisance for you then consider buying a uninterrupted power supply (UPS). This will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.

It is a good investment if your data are critical, because a power cut will cause any unsaved data to be lost.

Speeding up menus in XP

How to speed up menus in XP

Go to Start --> Run --> Regedt32

Go to HKEY_CURRENT_USER\Control Panel\Desktop

Locate the key called "MenuShowDelay" and it is probably set to 400.

Change that value to 150.

Reboot your computer.

You should notice a slight increase in the speed of your menus
