Ops.. è vero ho sbagliato: matrix, non maxtor.
Ovvio che mi riferivo a tutti i controller matrix e non ai driver degli hardisk.

Sul sito dell'asus c'è tutto, perchè dici che non hai trovato nulla???
Questo è il driver del tuo
controller
e questa è la spiegazione della procedura di installazione:
Installing Hard Disks
The Promise® controller supports up to a maximum of 4 hard disks; 2 parallel ATA and 2
serial ATA disks.
Do not attach this drive or any other hard drive to the FastTrak 376 controller before completing
this step.
1. Go to Windows [Start] [Control Panel], select [Switch to Classic View].
Then a [System] icon appears.
2. Double click [System] icon, select [Hardware] [Device Manager],
choose "RAID controllers" from the device list, click [Reinstall Driver].
3. Check "Install from a list or specific location", then specify the file path where the
driver is, e.g. X:\Drivers\Promise\WINXP. Click [Next],.
4. The Windows XP Setup screen will appear again saying
"Setup will load support for the following mass storage devices
-WinXP Promise FastTrak 376 (tm) controller". The FastTrak 376 driver
will now be copied on to the system and entered into the Windows XP driver database.
then click [Finish]
5. Finally, Windows XP will restart your computer.
6. Attach hard drive to the FastTrak 376 controller. Follow the instructions to complete the installation.
