BIOS Support of Non-Standard Panels
Ampro supplies flat panel BIOS images for many popular LCD panels. The chosen panel BIOS is
selected using SETUP. If an unsupported panel is desired, the standard video BIOS must be
modified to support the panel. Ampro can provide a BIOS modification kit to make these changes.
Contact an Ampro sales representative or Ampro Technical Support for information about the
Little Board/486e Flat Panel BIOS Modification Kit.
Once you have modified a BIOS, you must load it into the video BIOS section of an onboard Flash
EPROM device (already on the Little Board/486e CPU). Ampro provides a Flash programming
utility to do this.
To install a new video BIOS, follow this procedure:
1. Remove EMM386, HIMEM, and other extended memory managers from your CONFIG.SYS or
AUTOEXEC.BAT files. No extended memory managers can be loaded. (You must reboot the
system for these changes to take effect.) Alternately, boot the system from a floppy that has no
memory managers installed.
2. Remove the jumper on W1 to enable programming.
3. Enter the following command on the DOS command line:
PGMEBIOS VIDEO=filename
where
filename
is the name of the new video BIOS code file. (Frame the command so that
DOS accesses PGMEBIOS wherever it resides on your system.)
Leading and trailing spaces around the “=” are not allowed.
PGMEBIOS will return to the prompt indicating when programming is complete. DO NOT
REBOOT!
4. DO NOT remove power. Restore jumper W1.
5. Reboot the system and test the result.
