No drives attached.

The pins marked 'loopback' are on the motherboard alongside the 'power
switch' pins.

LEDs light up, but power supply fan does not run and no beeps or POST
messages.

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!

By 'BOOT' do you mean " any visible power up sequence " ?
or do you have a drive in there ?

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!!

Do you know memory cards are good ?
If you remove memory - do you get beep code ?

The SCSI LED would just show disk activity.
"Loopback pins" This is on the front panel ? or motherboard ?
