During last month I intensively used the Jordan svgaxxxx.bgi drivers, and
now have to say: it's great!
Some discovered nonconsiderable bugs, IMHO, don't crush this opinion.
1. When I hide mouse cursor (FN 2, int 0x33), then change cursor shape (FN 9),
garbage appears on screen.
2. After using FN 9 int 0x33 mouse hot spot always remains at point (0, 0)
3. When I try to out text string (System font only!) to the viewport
setting EXACTLY to the rectangle, occupied by this string, text does not
appear.
4. When I used mouse in standard VGA 320x200x256 0x13 mode
(without svgabgi drv), all x-coords of mouse-movement functions needs to
be recalculated (divided by 2). New svgaxxxm.bgi driver don't require
such recalculations (IMHO: it'is good! but...), so it may cause a situation,
when some old "mouse-oriented" programms (or parts of programms) would not
work correctly.
With best wishes. Paul.
PS. Ah, ya... I use svga256m.bgi driver on TRIDENT SVGA, 512K.
