The initial patch for the Cirrus extension has been written by Makoto -Suzuki (suzu). - - -Install -------- -To compile the VGA Bios you will need : -- gcc -- bcc -- as86 -- ld86 - -Untar the archive, and type make. You should get a "VGABIOS-lgpl-latest.bin" -file. Alternatively, you can use the binary file "VGABIOS-lgpl-latest.bin", -i have compiled for you. - -Edit your plex86/bochs conf file, and modify the load-rom command in the -VGA BIOS section, to point to the new vgabios image file. - - -Debugging ---------- -You can get a very basic debugging system: messages printed by the vgabios. -You have to register the "unmapped" device driver in plex86 or bochs, and make -sure it grabs port 0xfff0. - -Comment the #undef DEBUG at the beginning of vgabios.c. -You can then use the "printf" function in the bios. - - -Testing -------- -Look at the "testvga.c" file in the archive. This is a minimal Turbo C 2.0 -source file that calls a few int10 functions.
