PCI Buses
There are four independent PCI bus segments (dependent on model). The PCI buses comply with
the
PCI Local Bus Specification, Rev 2.3 .
ƒ
P32-A supports Slot 1 and NIC 1 on a 32-bit/33 MHz bus routed from the ICH6R.
ƒ
P32-B supports the optional second NIC routed through the PXH.
ƒ
P64-C supports two PCI-X slots routed through the PXH. In some models PC64-C will instead
support the riser slot if used for PCI-X.
ƒ
x8 PCI-Express* is available (optional) from the Intel® Adaptive Slot technology slot and
routed from the MCH.
ƒ
The Adaptive Slot is only available on Intel® Entry Server Board SE7221BK1-E (LX SKU)
and the Intel® Entry Server Platform SR1425BK1-E.

Riser Options
Peripherals and add-in cards are not included in your system and must be purchased separately.
For 1U models, you must use the 90° riser option to add in PCI, PCI-X or PCI-Express* adapters.
The 64-bit (white) slots cannot be used for 1u or if a 90° riser card is installed. Riser cards for the
Intel® Entry Server Board SE7221BK1-E are custom fit and provide either PCI 2.3 or PCI-
Express* capability. Please see the available accessories list at
