The BIOS knows this, of course :) I noticed that in my case, when the wrong ioports were probed (base + port_idx*offset) for port_idx being 2/3 - all of the return values were zero, instead of the expected values. You could probably use this to detect cases where PI claims a port is not present, but it really is. -- Robin Hugh Johnson E-Mail : robbat2@xxxxxxxxxx GnuPG FP : 11AC BA4F 4778 E3F6 E4ED F38E B27B 944E 3488 4E85
