hello,
I know that I have to write own code for displaying a mouse in SVGA =
mode.It's a bit boring and difficult to me.I've heard there r some kinds =
of new mouse drivers support SVGA,so where to get it and how to use it =
to show my mouse curser?
Another question:=20
I failed to selectpage of SVGA 101h in my own ISR timer in BORLAND =
C++ 3.1.and I know ISR programming in DJGPP is harder than realmode =
compilers.i know it's not allowed to do dos invoke in ISRs,but what to =
do then, to select SVGA page?
my code is here:
=20
union REGS r;
r.x.ax=3D0x4f05;
r.x.bx=3D0;
r.x.dx=3Dpage;
int86(0x10,&r,&r);
do it out of ISRs is ok.
what's wrong?
thanks a lot!
