hello,

I know that I = have to write=20 own code for displaying a mouse in SVGA mode.It's a bit boring and = difficult to=20 me.I've heard there r some kinds of new mouse drivers support SVGA,so = where to=20 get it and how to use it to show my mouse curser?

Another=20 question:

I failed to selectpage of SVGA = 101h in my=20 own ISR timer in BORLAND C++ 3.1.and I know ISR programming in DJGPP is = harder=20 than realmode compilers.i know it's not allowed to do dos invoke in = ISRs,but=20 what to do then, to select SVGA page?

my code is here:

union REGS r;
= r.x.ax=3D0x4f05;
=20 r.x.bx=3D0;
r.x.dx=3Dpage;
=20 int86(0x10,&r,&r);

do it out of ISRs is = ok.

what's wrong?

thanks a lot!
