             PERMEDIA reference card (with TI PERMEDIA chip).         tiperm.bin
             PERMEDIA LC reference card (with IBM PERMEDIA chip).     perm.bin

             PERMEDIA 2 AGP reference card (with TI PERMEDIA 2 chip). tip2agp.bin

VGABIOS.exe  The raw uncustomized video BIOS binary file.  DO NOT execute this
             file.  It is not designed to be run 'as-is' from DOS or Windows.
             It must be modified by the 'CONVERT' program below before being loaded
             into a suitable ROM.

CONVERT.exe  A utility for converting the vgabios.exe file into a loadable
             .bin file according to the instructions contained in a .cnv file.

*.cnv        Script files for producing loadable .bin versions of the BIOS.
             Used in conjunction with the 'convert' utility to customise the
             BIOS for a particular reference board (See TIP2AGP.cnv for latest
             descriptions of the customizable locations within the image).


----------------------------------------------------------------------------------
LOADING THE BIOS onto PERMEDIA, PERMEDIA NT or PERMEDIA 2 reference boards.

  1. Create a suitable directory on floppy or hard disk.
  2. Copy your chosen .bin file into this folder. (See table above for .bin selection).
  3. Copy the BIOSLOAD.exe and DOS4GW.exe files into the folder.
  4. If your card has DIP switches ensure DIP switch 6 on your card is ON.
  5. Reboot into DOS.
  6. Change into the newly created directory.
  7. Type: BIOSLOAD -r -f filename.bin
     Programming can take up to 10 seconds.  Progress is shown as several lines
     of dot,'O' or 'X' characters.  If your card already contains the same BIOS as
     the one being loaded the program will finish almost immediately as it only
     loads those parts which are different.  On some machines the display may go
     blank or flicker.  If this happens simply wait for at least 10 seconds before
     rebooting.
  8. Reboot and check the startup screen shows the correct video BIOS version and
     date as shown at the beginning of this file.
----------------------------------------------------------------------------------
CREATING A CUSTOMIZED VIDEO BIOS '.bin' FILE

  1. Edit a suitable .cnv file (tip2agp.cnv is suggested) with customized
     settings according to the type of target video card.  Don't forget to
     change the last few lines of the script to output to a new filename
     to avoid overwriting a standard .bin file.

  2. Run the CONVERT.exe utility by typing:-
       CONVERT @filename
     Where 'filename' is the name of your new .cnv file minus the .cnv extension.
     On completion a new .bin file should be created.
