The output from 'dmesg': sio0 not found at 0x3f8 sio1 not found at 0x2f8 The mainboard is a Iwill P55XB2 with Award BIOS v4.51PG. The serial ports are at the common locations in the BIOS: 3f8/irq4 and 2f8/irq3 Both ports work correctly from MS-DOS 6.22. Disabling the on-board serial ports and using a serial I/O card produces the same results. >How-To-Repeat: Simply boot the system and read the probe data. >Fix: Use an OS other than FreeBSD (i.e. DOS). Purchase a different motherboard and pray that it fixes the problem. >Audit-Trail: >Unformatted:
