You're both right, I think: he probably didn't quite understand your question. Normally, one jumpers IDE and SCSI drives to determine master/slave or SCSI ID orders, respectively. This would effect what would boot up first, and I gather this is what the tech support guy was referring to. But the bios should be able to determine, eg., which gets booted first, the SCSI set of drives or the IDE set. Now I also believe that using the D,E, and F options would allow you to boot primary slave, secondary master, and sec slave drives ahead of primary master drives. I haven't had any reason to test this, tho.

>>Now I'm confused....I thought this selection was made in mb Bios. I think abit is saying its made in SCSI host Bios.?<< I agree the Abit response is confusing. Asus uses Award bios as does Abit. From the Asus P2B manual #reply-4638004 TIP: You may configure two harddiscs to be both Masters using one ribbon cable on the Primary IDE connector and another ribbon cable on the secondary IDE connector. You may install one operating system on an IDE drive and another on a SCSI drive and select the boot disk through BIOS Features Setup. As Dave pointed out you can change a boot disk by changing a jumper setting. If you change an IDE disc from slave to master with a jumper setting it would become a boot disc. I do not recommend this approach. Likewise if you have two SCSI discs you can change the boot sequence by changing a jumper setting. A seven ID SCSI chain is scanned starting with ID 0, then ID 1, and continues downward. The first harddrive found in this sequence becomes the boot drive. If you change the ID of a SCSI drive by changing a jumper setting you can affect the boot sequence. If you have one SCSI harddrive and one IDE harddrive changing jumpers will have no affect on which drive boots. (with exceptions, ie you could use a jumper to disable a drive) I have no doubt that the Abit (Award bios) will allow you to select boot drives with the bios. With one IDE drive and one SCSI drive the choice could be made in the mobo bios. If you have two SCSI drives the boot selection can be made in the SCSI bios (provided it has boot target ID). Boot target ID gives one the option of starting the search for the boot disc at something other than ID 0. If you have two SCSI drives and one is ID 1 and the other is ID 2 you can set it to target ID 2 it will boot from the second drive. My question about IDE and SCSI harddrives in the same machine relates to the KOT concept. For example if NT has to be configured differently when it resides on a SCSI drive vs an IDE drive the cloning process may not work. My latest thinking on the KOT concept is to use two matched drives...thereby avoiding some of the unknowns. I will find out however. I will try installing NT on one of my IDE drives next. If all goes well I will see if it clones to a SCSI drive. Has anyone used Drive Image to restore an NT Image file to an IDE drive and then restored the same Image file to an IDE drive..did it work?
