Hi,
This motherboard has 3 serial pors:
COM0 as header from WPCM450
COM1 which is internally connected as SOL (Serial-Over-LAN)
COM2 Fast 16550 UART COM port on the I/O back panel from S1260 as a PCI
device.
COM0/1 are working:
com0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo
com1 at isa0 port 0x2f8/8 irq 3: ns16550a, 16 byte fifo
com1: console
COM2 is not working:

I found a dmesg from NetBSD[1]:
puc0 at pci0 dev 20 function 0: Intel S1200 UART (com)
com2 at puc0 port 0 (16550-compatible): ioaddr 0xf000, interrupting at
ioapic0 pin 16
com2: ns16550a, working fifo
com2: console
If it would help I can boot FreeBSD or Linux(Debian?).

dmesg is from GENERIC.MP with option XHCI_DEBUG because of a problem
with usb3
