3-volt A Boot Block 28F320C3 Flash memory component is used as the
BIOS flash device. The 28F320C3 is a high-performance 32-megabit memory component that
provides 2048 K x 16 (4 MB) of BIOS and non-volatile storage space. The flash device is
connected through the X-bus from the SIO.
3.7 Configuration and Initialization
This section describes the initial programming environment including address maps for memory
and I/O, techniques and considerations for programming ASIC registers, and hardware options
configuration.
3.7.1 Memory
Space
At the highest level, the Intel
®
Xeon
®
processor address space is divided into four regions, as
shown in the following figure. Each region contains sub-regions as described in following
sections. Attributes can be independently assigned to regions and sub-regions using the server
board registers. The Intel
®
E7320 and Intel
®
E7525 chipsets each supports 64 GB of host-
addressable memory space and 64 KB+3 of host-addressable I/O space. The server boards
support up to 8 GB of main memory for DDR-266 or DDR-333 configurations.
