Dolch Pac 65 - Corrupt Video Output

[Tony_G]

Hey All,

Before I head out and buy a PCI or ISA video card to test, I thought I might ask here if anyone has dealt with this before.

My DolchPac 65 seems to have a video issue - I've removed all the cards, the LCD driver panel and the unit seeks the floppy drive so I think it's posting. This is what I see on the motherboard VGA output:



I really think that the issue is going to be in the motherboard video (which will basically mean a swap of the CI6BM SBC) but I'm open to any suggestions - Including a new SBC, just need it to support PCI and ISA cards as I'm using the unit to run a HP Viper ISA card in it)

Thanks,

TonyG

Just an update - I managed to find a old machine here that had a Diamond Multimedia PCI VGA card in it so I grabbed that, dropped it in and the machine posts correctly.

Looks like the video part of the CI6BM has failed, which is annoying unless anyone has a suggestion of addressing it as those boards are going for "collector" money apparently...

I remember curiousmarc messing with Dolch earlier.
Probably a solder crack somewhere. This is common with these long PICMG SBCs.

I suppose you could re-solder the chipset, but it is probably a BGA. Difficult to do.

It would be better to buy a new full size PICMG 1.3. But finding a compatible one may be difficult.

Thanks - It is a "billion" pin package so I'm not even going to try and source a replacement.

I did try pressing on the board to see if anything changes but that wasn't successful.

I think you're right and I'll need to source a replacement. Thanks again though for the reply.
