Adapter considerations
Before you install adapters, review the following:
• Locate the documentation that comes with the adapter and follow those
instructions in addition to the instructions in this chapter. If you need to change
the switch settings or jumper settings on your adapter, follow the instructions that
come with the adapter.
• You can install 32-bit or 64-bit full-length or half-length adapters in the expansion
slots. Full-length adapters are installed in slot 1; half-length adapters are installed
in either slot 1 or 2.
• Your server supports 5.0 V and universal PCI adapters; it does not support 3.3 V
only adapters.
• Your server uses a rotational interrupt technique to configure PCI adapters.
Because of this technique, you can install PCI adapters that currently do not
support sharing of PCI interrupts.
• PCI slots 1 and 2 and the integrated SCSI controller are on PCI bus B; the system
board and all other integrated devices are on PCI bus A.
Note: PCI bus A = bus 0; PCI bus B = bus 1.
• The system scans PCI slots 1 and 2 to assign system resources. By default the
system starts (boots) devices in the following order: System SCSI devices, then
PCI devices.
Note: To change the boot precedence, start the Configuration/Setup Utility,
select Start Options from the main menu; then, select the PCI SCSI
adapter boot option
