Adapter considerations
Before you install an adapter, review the following:
• Locate the documentation that comes with the adapter and follow those
instructions in addition to the instructions given in this chapter. If you need to
change the switch or jumper settings on your adapter, follow the instructions that
come with the adapter.
• You can install full-length adapters in all five PCI expansion slots.
• The server supports 5.0V and universal PCI adapters; it does not support 3.3V
adapters.
• Your server uses a rotational interrupt technique to configure PCI adapters.
Because of this technique, you can install a variety of PCI adapters that currently
do not support sharing of PCI interrupts.
• PCI expansion slots 1 through 5 are on PCI bus 0. The system scans the AGP slot
and PCI expansion slots 1 through 5 to assign system resources; then, the system
starts (boots) the PCI devices in the following order, if you have not changed the
default boot sequence: PCI expansion slots 1 and 2, system board integrated drive
electronics (IDE) or SCSI devices, and then PCI expansion slots 3 through 5.
Note: To change the boot sequence for PCI devices, start the
Configuration/Setup Utility program, select Start Options from the main
menu, select Startup Sequence; then, select Second device (SCSI) to
designate the adapter boot sequence. See “Chapter . Configuring the
server,” on page 29 for details on using the Configuration/Setup Utility
program.
• For a list of supported options for your server, refer to
