Wait, do you mean you've installed NetBSD to the disk and had it boot fine on the same motherboard? In THAT case it's not hanging at POST, it's hanging just after POST. Are you sure the OpenBSD bootloader doesn't show itself -at all-? I'm pretty sure the first thing it does is print its banner, so if that's not even happening the BIOS must be loading the MBR in a way the OpenBSD MBR doesn't expect somehow. Perhaps you could try copying the MBR from a USB key with NetBSD over the USB key with OpenBSD, see if that makes a difference. Also please don't top post. -Nick
