Working with adapters
You can install up to five peripheral component interconnect (PCI) adapters in the PCI
slots on the system board of your server. See the xSeries 220 ServerProven list at
http://www.ibm.com/pc/compat/ for a list of PCI adapters that your server
supports.
Your server comes with an integrated video controller on the system board. When you
install a video adapter, the server BIOS code automatically disables the integrated
video controller.
Note: The illustrations in this document might differ slightly from your hardware.
The following illustration shows the location of the 33 MHz PCI slots on the system
board.
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 given in this chapter. If you need to
change switch or jumper settings on your adapter, follow the instructions that
come with the adapter.
• You can install full-length adapters in all PCI slots.
• You can install a 32-bit adapter in any of the PCI slots, but you might want to
install it in a 32-bit slot and use the 64-bit slots for 64-bit adapters.
• Your 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.
• The server has two PCI buses. PCI slots 1 and 2 are on PCI bus A, and PCI slots
3, 4, and 5 are on PCI bus B.
Note: PCI bus A is sometimes referred to as bus 0; PCI bus B is sometimes
referred to as bus 1.
