Hi, I would like to point out an issue with the enumeration of ISA serial devices in Syslinux. If I interpret the snippet below correctly, Syslinux looks up the device order with the BIOS, while Linux uses the fixed order 3F8,2F8,3E8,2E8. Note that this inconsistency is a real problem, as some motherboards (like e.g. a Supermicro X10DRi with default BIOS settings) have a different order

...COM0=2f8, COM1=3f8. I don't have enough different boards to play with to give you an accurate answer on which SM boards/firmware revisions are affected, but it isn't the first time I have seen something like this. > RBIL MEMORY.LST release 61 starting at line 31: > > --------S-M00400000-------------------------- > MEM 0040h:0000h - BASE I/O ADDRESS OF FIRST SERIAL I/O PORT > Size: WORD > Notes: the BIOS sets this word to zero if is unable to find any serial ports > at the addresses it is programmed to check at boot > DOS and BIOS serial device numb...
