2 Controller Cards + RAID & single hard drive = doesn't work

I rebuilt a homebuilt (Abit BX6R2 w/ PIII 700 MHz) to function as a music server. I had two identical 80 GB Seagates, so I picked up an ATA 133 / RAID PCI controller card. The system works fine w/ stripping RAID; however, I'd like to add third hard drive (non-RAID). I threw an old Maxtor 80 GB in and ran it off an ATA 100 PCI controller card. Now, the PC is looking at the single Maxtor as the boot disk (BOOT DISK FAILURE after Verifying DMI Pool Data) instead of the RAID, as it did prior to adding the single drive. Here's what I see as the IDE controllers come up.

(Mobo: ABIT BX6R2)

Drive 2 ST380021A Array 0 RAID 0
Drive 3 Not Detected

I've tried every Boot Sequence the Abit/Promise BIOS has:
A,SCSI,C
LS/ZIP,C
A,C,SCSI
C,A,SCSI
C,CDROM,A
CDROM,C,A
D,A,SCSI
E,A,SCSI
F,A,SCSI
SCSI,A,C
SCSI,C,A

It will work, again, if I disconnect the Maxtor. Any ideas how to get the system tp keep using the RAID as the boot disk? Thanks in advance

I'd put the maxtor drive on the mobo's secodary port, and the optical on the primary, and set the boot sequence as cd-rom, scsi. It's the SCSI setting that boots from the controller card. You have two controller cards of different brands and types... most mobo BIOSes can't handle that many boot roms!

If your definitely wanting to run your RAID 0 and another one or two drives, I would suggest the HighPoint Rocket RAID 454. I own this 4 channel RAID card, and do exactly what you propose. Channels one and two have the RAID 0 array, and channels 3 and 4 have a single hdd each. I could in theory have 4 drives on the latter two channels, RAID 1+0, or 8 single HDDs!

Thanks! I'll give it a shot; although I seem to remember the reason that in this computer's prior iteration (my main machine), I had to go with the 100 ATA controller as the BIOS/Mobo wouldn't recognize a hard drive that big. But I'll give it a shot now that its no longer the boot drive.

Thanks ProHandyman and Copenhagenlc! I'm booting to SCSI first via the Mobo BIOS, and the old Maxtor is connected to the Mobo IDE channels. XP recognizes it as a 76GB; so I can pull the ATA100 PCI card and use it elsewhere, and free up a PCI slot. Thanks again.
