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
