Odd as this may sound, there is nothing to be scared about when migrating to Microsoft's latest Operating System, XP.
To begin, you should start by making sure that your A7V has the latest BIOS. This can be obtained from the Asus Germany Web site at:
ftp://ftp.asuscom.de/pub/ASUSCOM/BIOS/Socket_A/VIA_Chipset/Apollo_KT133/A7V/
Here you will find the 1009.ZIP BIOS file that once extracted will be 1009.bin with the latest Promise Ultra 100 IDE drivers (2.01.1). You should use aflash.exe on a floppy disk with only the system files on it. (Format a floppy and check the "Copy system files" checkbox).
Once flashed, you be all ready to install XP over your existing operating system.
During the installation, when prompted, I suggest performing the following actions.
a) Install on current partition C:
b) Install XP into the current Windows directory (C:\Windows) and uninstall the existing operating system. (This will be one of the options) UNLESS you have Microsoft Application software like Outlook, Word, etc... In this case you should install it to a NEW directory as you could wipe out your existing .pst mailbox and application pointers by installing it over your old Windows!) The beauty here is that you go in and uninstall your old Windows later without deleting your important data or application pointers.
c) Convert the volume from FAT to NTFS when prompted with the various volume options.
Let Windows install completely and once that is completed, you will need to return to the Asus website and download the latest promise Ultra 100 drivers (to go with the updated Promise Ultra 100 BIOS).
You can find the Ultra 100 drivers again on the Asus Germany web site at:
ftp://ftp.asuscom.de/pub/ASUSCOM/TREIBER/CONTROLLER/IDE/PROMISE/
Here, you will find two different files, the one that you want is: U100_v200_b18.zip. The other file in this directory is intended for RAID controllers on the A7V133, so you don't want it.
After everything is complete, you'll want to download and install the latest 4in1 drivers as well as the VAGP410 update. This is all automatic in that when you click setup, it will prompt you to install the drivers (in the case of XP it only installs 1 new file in the 4in1 drivers) and then perform the AGP410 update after (since the latest 4in1 drivers include the AGP405 version which is old, don't ask me why.)
Anyway, once this is done, you're all set as far as most of your drivers go. To finish, you should run the Internet Explorer "Windows Update" function to download all of the latest XP patches, drivers and updates to finalize your installation.
I have been running XP on both the A7V133 and A7V with absolutely no problems, I'm sure you'll really like it. Much more stable than any other Windows platform!
In case you are wondering why I am pointing you to Asus Germany, I have found the Asus Tiawan and US sites do NOT have the latest drivers, whereas all R&D for Asus is done in Germany, they always have the latest and greatest drivers and BIOS's on their site.
