Installing an adapter

Complete the following steps to install an adapter:
50
Hardware Maintenance Manual: xSeries 330 Type 8674 and IntelliStation R Pro Type 6851
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/workstation supports 5.0 V and universal PCI adapters; it does not
support 3.3 V only adapters.
Your server/workstation 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.
