Partitions and Drive Letters

Normally, changing the first recognized partition/device in the BIOS means that the BIOS will attempt to boot from that device first; if no boot is found here it will go to the next device.

Agreed

This does NOT change the physical partition designation

My understanding is there is no physical designation on the drive itself. For example I took a SCSI "C" drive from a parts computer with working OS (DOS) and daisy chained it to a SCSI drive in an almost identical computer. All I did was change the SCSI ID and termination. The drive showed up as an E drive on the new machine. (the machine already had C: and D: drives. Are SCSI hard disks treated differently than IDE hard disks? Is there perhaps a designation in the controller? If I have SCSI and IDE and change the BIOS sequence to look at the SCSI drive first and the machine boots from the SCSI drive won't the SCSI drive then become the C: drive?

but simply looks there first.

and assigns C: to the first boot hard disk that it finds.

NT functions separate from BIOS will have to be addressed by another.

Agreed, the BIOS functions precede the OS functions but it is the OS that assigns the drive letter.

In DOS and Win95 I do not believe there are any software options to change drive letter designations of hard disks (removables and CD's can be changed). I am not so sure about NT.

IMO
