S875WP1-E TPS
6. BIOS Features
The Intel Server Board S875WP1-E 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 Intel Server Board S875WP1-E supports system BIOS shadowing, allowing the BIOS to
execute from 64-bit on-board 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 Intel Server Board S875WP1-E'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.

BIOS Flash Memory Organization

device. Internally, the device is grouped into eight 64-KB blocks that are individually erasable,
lockable, and unlockable.

Resource Configuration

6.2.1

PCI Autoconfiguration

The BIOS can automatically configure PCI devices. PCI devices may be on-board or add-in
cards. Autoconfiguration 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. Autoconfiguration information
is stored in ESCD format.
