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.

PCI slot 1 32-bit 33 MHz (J29)

PCI slot 2 32-bit 33 MHz (J31)

PCI slot 3 64-bit 33 MHz (J35)

PCI slot 4 64-bit 33 MHz (J39)

PCI slot 5 64-bit 33 MHz (J40)

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.
