a7n8x boot problem upon restart

Hello !

I have a strange problem here :
MB A7N8X Deluxe.
2 Maxtor HDDs on the SiI3112 controller, RAID0.

The RAID array is the boot disk (there are no other disks except for a cd-rom
drive).

Everything went fine until I got some bad clusters on my RAID array. I had to
open the PC and install a floppy drive in order to repair my installation (it
went very fine). I then removed the floppy and restarted the PC.
The problem the system will boot fine if I COLD boot the computer (after a power
down, it boots just fine).
If I warm boot the computer, whether restarting from Windows or pressing the
"hard-reset" button, the boot process hangs after the POST. It checks for a
bootable CD-ROM but it seems to be unable to find my bootable RAID array. After
some time, I get a classic "BOOT DISK FAILURE" error.

I tried to change my boot sequence and it did not help. I tried to reset my BIOS
to factory defaults and it did not help either.

Anybody has an idea of what's wrong here ?

Thanks a lot !
