Current Video and Printer Drivers
=================================
VIDEO DRIVERS: as of January, 1992
=============
This is a current listing of the video drivers included with CompuShow. Modes
in (parentheses) are simulated. Note that some modes may not be available on
your video adapter. For example:
- 16 color 1024x768 requires a 512K VGA,
- 256 color 640x480 requires a 512K VGA,
- 256 color 1024x768 reguires a 1M VGA, and
- 256 color modes on an 8514/A adapter require the memory expansion.
Also, VGA adapters that are built-in to a system board or bundled with a
computer (unless you're getting a specific name-brand board), are frequently
low-end (cheap) adapters, and probably don't have "Super-VGA" capabilities.
Finally, remember that all IBM standard graphics modes are 'built-in' to
the program. If your graphics adapter doesn't go beyond the standard modes,
then you don't need a video driver.

CAUTION: Problems with Oak VGAs
-------------------------------
There seems to be a serious problem with the Oak BIOS, and if you try to use
the System Configuration program CSHOWI to test (or CSHOW to display) an Oak
mode which isn't available on your VGA, it will still attempt to set the
graphics mode, and throw the VGA into a configuration where it will no
longer do ANY extended graphics modes until you re-boot!
The only way around this bug in the Oak BIOS is to select the Oak driver
(perform one test in CSHOWI and then ESCape to skip the rest) and set up
VIDEO.DAT manually:
- With the Oak video driver selected, use CSHOW to display a graphic in
each video driver mode UNTIL YOU ENCOUNTER A MODE THAT DOESN'T WORK.
- Re-boot the computer and continue testing.
- Once you have a list of the modes which DO WORK, set up VIDEO.DAT with
the corresponding letters:
COPY CON VIDEO.DAT
STVW^Z (^Z means hold down the CTRL key and type Z.)

Printer Drivers: as of January, 1992
----------------
Note that the <Q>uality print mode of MOST COLOR PRINTERS and the LASERJET
and DESKJET at 300dpi requires MORE THAN 640k of memory, as CompuShow must
expand, rescale and dither the entire image to the 'virtual screen' (VScreen
on the Shift-F1 box), before it starts to print. This means if you don't have
EMS or XMS memory, you'll be limited to the <F>ast print mode.
The following printer drivers are included with the enhanced program:
