BIOS Build Date
Date in MM/DD/YY format on which Dynatem built the system BIOS binary file.
System BIOS Size
Size of BIOS exposed in low memory below the 1MB boundary. Commonly, 128KB
would mean that the BIOS is visible in the address space from E000:0000 to
F000:FFFF.
CPM/CSPM/BPM
Modules
Indicates the names of the key architectural modules used to create the system BIOS
binary file. The CPM module provides the CPU family support; the CSPM module
provides the northbridge support; and the BPM module provides the board-level
support.
The CPU information is normally obtained by querying the Processor Brand String in the CPU’s MSRs; the method
used to achieve this is beyond the scope of this document.
The system memory information does not describe physical RAM; rather it describes the RAM as configured,
subtracting RAM used for System Management Mode, Shadowing, Video buffers, and other uses. This provides
realistic values about how much memory is actually available to operating systems and applications.
The Real Time Clock fields are editable with keystrokes. To navigate through the MM/DD/YYYY and HH:MM:SS
fields, use the TAB and BACKTAB keys. The hours are normally specified in military time; thus 13 means 1pm, or
one hour after noon, whereas 01 means 1am, or one hour after midnight. When the cursor leaves RTC fields, they
either affect the battery-backed RTC right away, allowing the system to continue with your new settings, or
they revert back to old values if the new values are not valid entries.
B.5
Exit Setup Menu
The Exit menu provides methods for saving changes made in other menus, discarding changes,
or reloading the standard system settings. This menu is shown in Figure 3.2 below.
To select any of these options, position the cursor over the option and press the ENTER key.
Pressing the ESC key at any time within the Setup system is equivalent to requesting “Exit Setup
Without Saving Changes.”
