This is the first maintenance release for GRX 1.03. It contains the
following bugfixes/enhancements:
- The VESA driver (vesadrv.vdr) failed to recoginize the supported
VESA modes on some cards due to a feature in some VESA BIOS
extensions. The updated driver in this release fixes this problem.
NOTE: until the new VESA driver becomes part of GO32 (i.e. until
the next DJGPP maintenance release) use the 'driver' field of the
GO32 environment variable to explicitly load the new driver.
- The VGA memory size detection logic in the VESA driver has been
upgraded.
- The convex polygon fill code now handles the two point (line)
case properly.
- The release also contains the PCX screen dump code previously
posted to the mail group.
- The libraries are now compiled with GCC version 2.5.7.
The udated files are in the ZIP archive 'grx103m1.zip'. The ZIP file
was created using the standard DJGPP directory structure: the GRX files
are under '.....contrib\libgrx'. Unzip this file in the DJGPP base
directory AFTER the original GRX archives. If you reinstall GRX you will
have to reinstall this archive as well. If you use PKUNZIP, don't forget
the '-d' switch!
IMPORTANT: Please delete the VESAINFO.* files from the 'drivers' sub-
directory (NOT 'ndrivers'!) of the GRX tree. These files are obsolete,
on some VGA cards may even lock up the system!
