Well, my mainboard (KT333) only has options for booting from southbridge IDE, internal RAID, and SCSI. There is no way to select between multiple bootable PCI cards (true SCSI and IDE). Although it is possible for the computer to boot by rearranging the cards, the drive order at the hardware level is then different from Windows so the DOS applications, run from VFD, are confused.
It would be nice to upgrade my system with a new mainboard, CPU(s) and RAM. However, the PC3200 is not available yet, so I must wait for a few months at least.
