That shouldnt be possible - we are supposed to start at 0x203 and skip the
problem area.
static int isapnp_next_rdp(void)
{
int rdp = isapnp_rdp;
while (rdp <= 0x3ff) {
if (!check_region(rdp, 1)) {
isapnp_rdp = rdp;
return 0;
}
rdp += RDP_STEP;
/*
* We cannot use NE2000 probe spaces for ISAPnP or we
* will lock up machines.
*/
if(rdp >= 0x280 && rdp <= 0x380)
continue;
}
return -1;
}
If you can find out why that port is being touched I'd like to know
