I'm having a problem installing Win2k on a system with a Promise Ultra100 modded for RAID. The system previously had Win2k on it using the Motherboards IDE. With the promise board installed it makes it to the point in the Win2k installation where is says its searching for plug and pray devices and gets a BSOD about 2/3 through that says "Hardware Failure". Win98 installs fine and the RAID works great. Win2k still installs properly if I use the onboard IDE ports instead of the Promise. The board works fine with Win2k on my other system (it has a different motherboard).
The system:
Epox K7XA w/audio
Athalon SlotA 750mhz
Maxtor G400 Dual Head
256mb ram
2 - Seagate 18.9gb ATA100/7200rpm
52X cdrom
TDK VeloCD CDRW
DLink NIC
 
The same Promise board works fine with 2k in:
ASUS A7V
800mhz TBIRD
256mb ram
2- IBM GXP75 30.6gb
eVGA GeForce2 GTS
Soundblaster Live! Platinum
Pioneer 115 DVD
DLink NIC
 
It seems like Win2k doesn't like the EPOX MB with the Promise Card. Win98 installs fine.
Thanks
