4. Reattach the AC power cables and power on the server.
5. Power down the server and again remove all AC power cables.
6. Replace the jumper at jumper block J8G1 so that it covers pins 1 and 2.
7. Replace the chassis cover and re-attach the AC power cables.

BIOS
The S875WP1-E server board uses an Intel/AMI BIOS that is stored in the Firmware Hub (FWH)
and can be updated using a disk-based program. The FWH contains the BIOS Setup program,
POST, the PCI auto-configuration utility, and Plug and Play support.
The S875WP1-E server board supports system BIOS shadowing, allowing the BIOS to execute
from 64-bit onboard write-protected system memory.
The BIOS displays a message during POST identifying the type of BIOS and a revision code. The
initial production BIOS is identified as WP87510A.86B.
When the S875WP1-E server board’s jumper is set to configuration mode and the server is
powered-up, the BIOS compares the processor version and the microcode version in the BIOS and
reports if the two match.
PCI Auto Configuration
The BIOS can automatically configure PCI devices. PCI devices may be onboard or add-in cards.
Auto configuration lets a user insert or remove PCI cards without having to configure the system.
When a user turns on the system after adding a PCI card, the BIOS automatically configures
interrupts, the I/O space, and other system resources. Any interrupts set to Available in Setup are
considered to be available for use by the add-in card. Auto configuration information is stored in
ESCD format.
IDE Auto Configuration
If you select Auto in the BIOS Setup program, the BIOS automatically sets up the two
IDE connectors with independent I/O channel support. The IDE interface supports hard drives up
to ATA-66/100 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape
drives, and Ultra DMA drives.
The BIOS determines the capabilities of each drive and configures them to optimize capacity and
performance. To take advantage of the high capacities typically available today, hard drives are
automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4, depending
on the capability of the drive. You can override the auto-configuration options by specifying
manual configuration in the BIOS Setup program.
