BIOS Build Utility (ATBIOSPR.EXE)
The BIOS Build utility program, ATBIOSPR.EXE, allows you to re-program the BIOS.
Incorrectly programming the BIOS can completely halt operation of the cpuModule, requiring it to
be returned to the factory. Do not attempt to reprogram the BIOS unless you fully understand the
procedure.
BIOS Organization
The cpuModule BIOS is in a 128k byte Flash EPROM. The ROM is at addresses E0000H through
FFFFFH.
The first 64kbytes, from E0000H to EFFFFH, contains the Setup program which is executed when
the {Delete} key is held during boot. The upper 64kbytes, from F0000H to FFFFFH, contains the
normal PC BIOS of the cpuModule.
Using BIOSBLD
The Program is run by entering the following command line:
ATBIOSPR <file_name> 1 24
where:
<file_name>:Name of the file to be programmed into the Flash EPROM.
Example:
To reprogram the BIOS with the file MYROM.400 (which is 128KB long), you would use the com-
mand line:
ATBIOSPR MYROM.400 1 24
