Here's the mobo specs (im home now)...

AcerOpen AP53(AX) Motherboard:
AP53R3C0

One USB connector for 2 ports
Dallas DS12887A or DS12B887 RTC/Battery.

Motherboard supports PS/2 mouse
AT Keyboard
IrDA - Laptops, PDA, wireless stuff 115Kbs transfer rate at 1 meter.

PCI 2.1 Compliant - OFF because some other weirdo issues
USB Functionality:

NOTE from booklet: USB Shares INTD with PCI slot 4 therefore if you enable
USB only PCI cards that do no not require IRQ such as VGA can be installed
in SLOT 4. The PhP BIOS assigns an IRQ to VGA only if the VGA requests for
it...hmmmmm
