Just connect the HDs to the IDE ports, provided that they're declared as
Master and Slave if they're on the same cable.
Don't modify anything in the BIOS. You're booting on the SCSI and you'll
continue to do so (at least at DOS level !). Normally, starting the
computer, next time, when the Hds will be connected shouldn't change
anything. However if you have several letters assigned to different
partitions and if you have primary active partitions declared on your IDEs,
the letter order will be changed. Let assume Windows is installed on the D:
or E: SCSI logical unit, SCSI disk being alone, you'll probably not be able
to boot with the IDEs because the IDE's primary partition letters will steal
the SCSI's D: and E: letters. The following SCSI partitions will come after
and the rest of the logical IDE partitions will come at the end.
Example:
SCSI alone:
C: SCSI boot, D: SCSi utilities, E: SCSI Windows 2000, F: applications # 1,
G: your own productions #1
C is the primary active partition ==> bootable
D, E, F; G are logical disks installed on the extended partition
Windows will start on E:
IDE1 alone:
C: IDE1 boot and Windows 98, D: applications # 2, E: your own productions #2
C: is the IDE1 primary active partition ==> bootable
D, E, are logical disks installed on the extended partition
Windows will start on C:
IDE2 alone:
C: IDE2 boot and Windows 2000, D: applications #3, E: your own productions
#3
C: is the IDE2 primary active partition ==> bootable
D, E, are logical disks installed on the extended partition
Windows will start on C:
SCSI + IDE1 only:
C: SCSI boot, D: IDE1 boot and Windows 98, E: SCSi utilities, F: SCSI
Windows 2000, G: applications # 1, H: your own productions #1, I:
applications # 2, J: your own productions #2
Windows won't start because E: contains utilities
SCSI + IDE1 + IDE2:
C: SCSI boot, D: IDE1 boot and Windows 98, E: IDE2 boot and Windows 2000, F:
SCSi utilities, G: SCSI Windows 2000, H: applications # 1, I: your own
productions #1, J: applications # 2, K: your own productions #2, L:
applications #3, M your own productions #3
It will probably boot on the Windowz 2000 version installed on the IDE2 HD.
I say "probably" because the DOS configuration files may call pieces of
software not present on the old E: (disk drivers, memory management, ...).
The best way to prevent such a situation is to boot on a floppy disk, then
run partition magic (ver. 8 if you have disks larger than 40 GB), declare
the primary partitions as hidden on all the disks except SCSI HDs and
reboot.
The next time, all the SCSI disks' letters will remain in the places they
nominally have, then the letters of the logic disks of the extended
partition of the IDE1 will appear followed by the letters of the IDE2
mounted as slave or connected to the secondary IDE port.
The draw back is that you loose the space of the IDE primary partitions.
However if nothing of valuable is on them but boots and windows, with
Partition Magic, you'll be allowed to reduce these partitions to 7.8 MB FAT
16. The rest can be one logical disk or more within the extended partition
I've five disks SCSI's IDE's & one SATA. They're arranged following what I
said. I can add or remove disks with diferent number of logical
disks/partitions, nothing wrong appears because the entire system is
installed on the first IDE disk. I have also a full copy of the IDE bootable
disk, hidden on the second IDE, waiting for activation in case of major
problem. Just to swap the disks and go ahead !
May be a little confusing ! The rule is that primary partitions appear
first, followed by the letters of the bootable disk then by the most ranked
disk ie the primary master finally by the lower priority one the secondary
slave.
