Non-disk-array models that are supplied with a preinstalled wide hard
disk drive use a 16-bit internal connector.
Non-disk-array models that are not supplied with a
preinstalled hard disk drive or supplied with a narrow hard disk drive use
an 8-bit internal connector.

The drive from which you will start the non-disk-array server
(also known as the boot or startup drive) should have a SCSI ID of 6.
Therefore, if the server was not supplied with a preinstalled hard disk
drive and you install hard disk drives, set the SCSI ID of the first drive
(the boot drive) to 6.
NOTE:
If the BIOS is version M54PE_08 or earlier and you have
two PCI SCSI adapters
installed in the PCI slots, the
system will start from the hard disk drive attached to the
SCSI adapter with the least amount of
Read-only memory (ROM) and the lowest ROM address space.
(In the case of equal
ROM size, the system scans from slot 1 to 3 and assigns slot 1
as the lowest ROM address.) Therefore, in order for the system
to load the operating system correctly, connect
the startup drive to the SCSI adapter
with the lowest ROM address space.
If the version of BIOS is later than M54PE_08, and you have two
PCI SCSI adapters installed in the PCI slots, the system will start
from the hard disk drive attached to the SCSI adapter in descending
order from slot 3 to slot 1.
If the disk-array model
was supplied with a preinstalled hard disk drive in bay 1, this drive
is the startup drive, and it already has a SCSI ID of 0.
The SCSI ID of the preinstalled hard disk drive in bay 1 of non-disk-array
models is set to 6.
Refer to the instructions supplied with the SCSI devices
for information about setting a SCSI ID.
The SCSI-2 adapter in the server
has two internal connectors and one external connector:
On all models, the external connector is for 16-bit cable.
The SCSI-2 Fast/Wide PCI Adapter supports a total of seven
8-bit or fifteen
16-bit SCSI devices.
The SCSI-2 Fast/Wide PCI-Bus Adapter supports a total of fourteen 16-bit SCSI devices.
NOTE:
If you plan to install both internal and
external SCSI devices, you must follow the instructions given in
'External SCSI Devices' in addition to the instructions in
this section.
