Memory Control Options
• Memory
♦ Memory Test – [Fast], [Standard], or [Exhaustive]
* If this field is set to [Fast], only basic memory tests are performed during POST to shorten
POST time.
* If this field is set to [Standard], more than basic tests are performed, but POST time is
increased.
* If this field is set to [Exhaustive], more rigorous tests are performed on memory, but this
takes a significant amount of time for POST to complete.
♦ Memory Hole – [Disabled], or [1MB]
This field specifies the size of an optional memory hole, below 16 MB. Access to the memory
addresses inside the memory hole region are forwarded to the PC/104 bus, where memory
mapped PC/104 devices have access.
♦ Shadow D000-D3FF – [Disabled] or [Enabled]
These Shadow fields specify if BIOS option ROMs in the indicated segments should be
shadowed to RAM. Shadowing option ROMs can potentially speed up the operation of the
system. The indicated segments are only for option ROMs present on add-on PC/104 and
PC/104-Plus cards.
♦ Shadow D400-D7FF– [Disabled] or [Enabled]
♦ Shadow D800-DBFF – [Disabled] or [Enabled]
♦ Shadow DC00-DFFF – [Disabled] or [Enabled]
Power Management and Advanced User Options
• Power Management
♦ ACPI – [Disabled] or [Enabled]
* If this field is set to [Enabled], the Advanced Configuration and Power Interface API is
turned on and available for any Operating System that supports ACPI power states.
♦ APM – [Disabled] or [Enabled]
* If this field is set to [Enabled], the Advanced Power Management API is turned on.
This power management feature is an older standard and may not be as widely supported
today as it once was. The current preference for power management control is ACPI.
• Advanced features
♦ Post Memory Manager – [Disabled] or [Enabled]
* If this field is set to [Enabled], the Post Memory Manger API is turned on. The Post
Memory Manger can be used by BIOS option ROMs to allocate memory in a well
defined way.
♦ CPU Serial Number – [Disabled] or [Enabled]
* If this field is set to [Enabled], the internal serial number in the Intel CPU is accessible by
the Operating System and/or Applications that can make use of this information..
♦ Watchdog Timeout (sec) – [select a number between 255 seconds and 1 second, in 1 second
increments] or [Disabled]
* If this field is enabled by selecting a time interval (1 to 255 seconds), it will direct the
watchdog timer to reset the system if it fails to boot the OS properly. Refer to the
watchdog timer section in Chapter 3 for more information.
