The exact layout is subject to change as determined by Intel. A 64 KB block is available for
storing OEM custom logos.
The flash ROM contains the necessary drivers for onboard peripherals including the following:
Ethernet
SATA
SAS
Video controllers
The Flash Memory Update utility loads the BIOS image into the flash.
The complete ROM is visible, starting at physical address 4 GB minus the size of the ROM,
which on this server board is 8 MB. Due to shadowing, none of the flash blocks are visible at the
aliased addresses below 1 MB.

14.4 Fan Speed Control and Thermal Management

The BIOS and BMC software work cooperatively to implement system thermal management
support.
This is accomplished with a combination of memory and processor thermal management as
described in the sub-sections below.
14.4.1

FBDIMM Thermal Management

The BIOS implements support for Static Closed Loop Thermal Throttling (CLTT) in conformance
with the requirements indicated in the Common Fan Speed Control and Thermal Management
Platform Architecture Specification (PAS). Intel Corporation and the Intel
S7000FC4UR Fan Speed Control and Thermal Management Platform Architecture Specification
(PAS), Intel Corporation.
14.4.1.1 Fan Profile Option
BIOS Setup provides a fan profile option allowing the user to influence the system acoustic
profile. This menu item provides two options:
The performance option results in higher system performance at the expense of a
slightly increased acoustic signature.
The acoustic option results in a reduced acoustic signature using more aggressive
memory throttling.
14.4.1.2 BMC Get Thermal Profile Data Command
The BIOS issues the BMC Get Thermal Profile Data command during early POST to retrieve
the appropriate thermal profile as indicated by the user in BIOS Setup (performance or
acoustic). If the BIOS cannot retrieve the thermal parameters from the BMC, it uses the Memory
