 Sorry about the confusing terminology. I read the labels off of the
 A7V (1.02) motherboard. The Promise ATA100 is labeled Primary/Secondary
 ATA100 while the '686A is Primary/Secondary IDE.

 When I was using this configuration, I was had the system boot
 in this order:
    DVD-ROM (on VIA '686 secondary-master)
    ATA100/SCSI (Promise primary-master)
    Floppy
    IDE (disabled, as I didn't have any other drives attached)
 
 The boot order of the Promise/SCSI is as per above (ATA100, then
 SCSI). My SCSI card isn't installed.
 
 Anything in particular you're interested in my BIOS configuration?
 
 I also get this behavior if I run only on the VIA '686 primary and
 secondary connectors:
    UDMA66 drive on primary-master
    DVD-ROM on secondary-master
 
 Boot order is
    DVD-ROM
    IDE
    floppy
    ATA100/SCSI is disabled
 
 I've also disabled the Promise ATA100 bus's BIOS in my current
 setup.
 
 
 Ken
