Example 1
To program the S64P80.DAT video BIOS (which operates the Sharp
64P80 flat panel and CRT in simultaneous display mode) into SSD1
whether or not the current video BIOS is in SSD1, enter the following
command:
PGMVIDEO S64P80.DAT SSD1 /P
Remarks
The video BIOS is typically 40K and resides in the C0000-C7FFF and
C8000-CBFFF areas. To use the new video BIOS, set the BIOSDEV
jumper, W2[5-6], to the programmed SSD. Also, enable the video BIOS
areas, C0000-C7FFF and C8000-CBFFF. To enable the video BIOS
areas, change the jumpers on W2[1-2] and W4[1-2] or change the ROM
enable options in SETUP. Change the ROM enable options and jump-
ers W2[1-2] and W4[1-2] accordingly to accommodate your current ROM
enable and jumper states. For complete instructions on enabling and
disabling the video BIOS, see the Console devices chapter.
If the video BIOS is programmed and no display results occur, then
adjust W2[1-2] and W4[7-9] by trying four options: on, on; on, off;
off, on; or off, off (refer to Table 7-4). Also, confirm that the VGA disable
jumper, W4[5-6] is installed. If the display still does not work, then
check the cabling and/or the video BIOS, programmed for your flat
panel. To restore the CRT/VGA display, reprogram the default video
BIOS by using the serial console to access the PC-500.
When the SCSI.DAT BIOS is combined with the video BIOS, then both
BIOSs can be programmed at once. For more information on combining
these two BIOSs, refer to the README.DOC on the SCSI utility disk.
