Hi,
I in my quest to get my Diamond SpeedStar 24 graphics card working I am looking
at some code from Linux. This code uses a routine called ioperm like:
void perm_ports(int perm)
{
ioperm(0x3c2, 1, perm);
ioperm(0x3cc, 1, perm);
}
I can find no such routine in FreeBSD. I notice that it is -also- used
in the XFree86 distribution of X386/lib/X11/etc/ati.test.c which is
for the ATI card. It is used like this:
ATIExtReg = *((short int *)bios_data + 0x08);
ioperm( ATIExtReg, 2, 1 );
I am not sure exactly what this does. If someone could tell me where to find
this routine, send me one if they have it, or just tell me what it does so I
can write my own, I would appreciate it very much.
I would also appreciate any help people might have wrt writing a clock
setting routine for the Diamond SpeedStar 24 graphics card.
