Programming The Video Bios; Additional Notes On Video Bios - Octagon Systems XE–700 Reference Manual

Programming the video BIOS

The XE–700 SBC BIOS is factory configured and programmed for a 640 x 480 CRT
monitor. If you wish to use a flat panel you must reprogram the video BIOS with
the appropriate flat panel driver. To reprogram your video BIOS, load the
appropriate driver from the Octagon CD ROM \700\VIDEO\BIOS subdirectory.
Note Refer to the README.DOC file on the disk for a list of the supported flat panel
displays. If your particular display is not currently listed, contact Octagon
Technical Support (303–426–4521) for assistance.
To load a new BIOS to support a different flat panel:
1. Attach a CRT monitor, a PS/2 compatible keyboard, and a CompactFlash to the
XE–700 SBC.
Note If a monitor and keyboard are not available, connect the XE–700 SBC to your PC
by using a remote serial console. Refer to the Serial Console section in the Console
devices chapter.
2. Power on the XE–700 SBC.
3. Select the correct .DAT file (located on the Octagon CD ROM \XE–700\BIOS
disk). Example: LQ12S31.DAT
4. Run VIDEO700. Example:
XE–700 SBC C:\> VIDEO700 BIOS.ROM A1_TFT.BIN
5. Reset the XE–700 SBC.
6. Use PHLASH to program the new BIOS into the XE-700. See the BIOS
programming using PHLASH.EXE section in Chapter 16.
7. Power off the system.
8. Install the flat panel and then apply power to the system.

Additional notes on video BIOS

If the new video BIOS does not work correctly, set the V switch (SW4, position 3) to
Off and boot to serial console on COM1. Reprogram a known good BIOS (such as
the BIOS provided on the Octagon Product CD) set the V switch to on, and reset
the system. See the BIOS programming using PHLASH.EXE section in Chapter
16.
