and 2, both expansion slots are configured as 64-bit 100 MHz slots. See
"System-board switches and jumpers" on page 5 for the location of jumper
JPCIXB1.
Note: If you install both a 33 MHz adapter and a 66 MHz adapter, the PCI bus
will operate at the slower speed.
v The server is designed specifically for PCI-X adapter support, but it also supports
PCI adapters.
v The server supports 3.3 V and universal PCI and PCI-X adapters; it does not
support 5.0-V-only adapters.
v The integrated video controller is on PCI bus 1. The integrated Ethernet
controllers and the integrated SCSI controller are on PCI-X bus 2. PCI-X slot 1
and PCI-X slot 2 are on PCI-X bus 3.
v The server scans PCI-X slots 1 and 2 to assign system resources. By default,
the server starts (boots) devices in the following order: system SCSI devices; PCI
and PCI-X devices; then, IDE and SATA devices.
Note: To change the boot precedence for PCI and PCI-X devices you must
disable the devices through the Configuration/Setup Utility program. Start
the Configuration/Setup Utility program and select Startup from the main
menu. Then, select Startup Sequence and use the arrow keys to specify
the startup order. For more information, see the User's Guide on the IBM
Eserver Documentation CD.
v If you plan to install either an optional SCSI adapter or an optional redundant
array of independent disks (RAID) adapter, you can install it in either of the
PCI-X slots if the size of the adapter permits. The server supports a variety of
RAID adapters for both internal and external configurations. For the most current
list of supported RAID adapters, go to http://www.ibm.com/pc/us/compat/. For
details about installing a RAID adapter, see the documentation that comes with
the adapter.
Note: A 64-bit 133 MHz adapter can be installed only in slot 1, and only if the
jumper block on jumper JPCIXB1 is on pins 2 and 3.
