Log of changes for the Universal VESA VBE
-----------------------------------------
Version 4.1 (24 Sep 1993)
- Added support for > 1Mb of RAM for Cirrus 5426/28 chipsets. Also
fixed page flipping problem in 640x480x16 color mode.
- Fixed buffer size problems for S3's
- Removed all cli/sti instructions in bank switching routines. These
seem to have been a cause of a number of problems and are not
required anyway.
- Fixed problems with DAC detection not resetting the DAC correctly
for Diamond SS24 DAC's. Also added code to reset the DAC if not
done correctly by the BIOS.
- Fixed support for Page flipping on AL2101 and read/write bank
support.
- Fixed page flipping on some cards like the ET3000 in the 256 color
modes (I hope).
Version 4.0 (18 Sep 1993)
- Added support for the ET4000/W32 and OAK OTI-087 SuperVGA's.
- Fixes for the following video cards:
- Paradise
- Cirrus Logic
- S3
- Added special protected mode support interface. You can now copy
relocatable versions of the bank switching and page flipping code
into your own programs to run at high speed. This will work in
both 16 and 32 bit protected mode (note that the interface is
_not_ the same as the interface to the actual VBE routines, but
much simpler and lower level for simplicity and speed).
- Major changes and restructuring of the code in the Universal VESA
VBE. This makes it take less memory when installed, a lot simpler
to modify and add support for new video cards. The Universal VESA
VBE is now completely autonomous from the MGL package.
- The Universal VESA VBE now only requires 3k of memory when resident,
through re-engineering the internals. It nows takes the same amount
of memory not matter how many video cards are supported. All but
the code required for the installed SuperVGA is removed from
memory when the TSR goes resident.
- The Universal VESA VBE no longer has any 386 dependant code in it,
so will work even on old 8086 machines.
- Added 64k color mode support for the RealTek
