To an extent, the 'complaint' is only that modern BIOS and OS haven't undone that long legacy of ambiguity, and 'auto' is a 'don't really care' option. And why try? The physical serial ports are being phased out on many newer MB. Lucky to get a header block. Server grade system boards might be expected to keep 'a' serial port for a while yet, but most laptops have long-since shed them. Scare resources are perhaps better applied to sorting other 'challenging' bus device issues. Such as the vexation that the current rate of progress/economic necessity is causing I/O devices in general to appear, live a *very* short economic life, and be replaced by yet-another newer one at a rate that doesn't allow thorough testing even IF there has been time to code a driver. That's not limited to F/OSS, either... :-( BillReceived on Sat Oct 13 2007 - 04:01:58 UTC
