Default Mystery motherboards - Compaq Deskpro SB - won't boot

I have acquired three Socket 370 motherboards, marked 305 Rev0AS21, also
with part numbers 011305-101 and 011306-000.

From what I can tell these are the basis for a Deskpro SB (?) machine, but
none of them will boot! They have on-board graphics, and a memory card
marked "4Mb AIMM 133Mhz CL3" is provided for the AGP slot.

I have tried various processors and memory sticks - the LEDs on the board
light when I plug in the PS and trip the 'power on' pins, but no boot!
I notice that some of the pins to the panel are marked SCSI LED and
LOOPBACK - are either of these crucial to the boot sequence?

Any help appreciated!!
