The following motherboard is marked P2-BX but is NOT an ASUS motherboard despite a similar naming scheme. The board came into work with the paper motherboard manual (not at work at the moment). The manual is a very plain looking manual, not like Asus' typical documentation. Someone has incorrectly listed the P2-BX as an Asus motherboard on a couple of sites, but I can guarantee after looking closely at the board it's not. If I remember correctly it is a Slot 1 motherboard.
Cheers,
