I do not know. Being you are running a Compaq OEM board with Compaq BIOS it may require a specifig .cfg file that works with that board/bios. Have not checked the Compaq archives but that would be the last resort for a possible working .cfg. Otherwise the Ultrastor could have a fault and nothing …

From my old experience with VIA MVP3/ALI ALADDIN AT format boards with dual power connectors (AT/ATX) some had jumpers for selecting the power supply type. I remember this because at the beginning one got fried because i did't knew to change the jumper position and they were set by default for AT …

Look at the tracks connecting to resistors from the pin headers and check the resistors next to the jumper header. Cheers, Hi, Sorry for the extremely late reply - I ended up taking this board to a local computer repair shop and it turns out I shorted that pin header connector. In the end I ended …

Probably bad caps, and being SMT that makes it harder to figure out which ones. Are you sure the PSU is also not failing ? added: did the batteries die ? I see it uses an external battery and may not boot up if they are dead.... Hi, So sorry, just seeing this now! Thank you for your kind reply! I …

Make sure your black and white wires is actually momentary power button. Some have push on, push off, you can tell by sound of click and the button are in different positions. Make sure the resistors next to the jumper block is not blown as I sometimes get sparks if I touch wrong pins to that power …

There are little chips next to these pin headers usually one probably got shorted. You could try to replace them Perhaps it is one of the transistors?

When you got the board started, by shorting the two pins, how much 'testing' did you do e.g. - power on board by shorting two pins (OK) - power off board by shorting same two pins, either momentarily or 4 sec hold (?) - reset powered on board using other two pins (?) - repeat any of the above steps …

On second reading, your JP7 pin block (2 x 10) differs from that shown in the link (2 x 12), so the quoted pins 10 & 11 are probably wrong for this board version. However, the silkscreen printing on your board does seem to suggest that the 2 two pins shown below in red are reset (RST) and the two …
