POST card

Hey guys. Has anyone ever had experience working with a POST card diagnostic reader? I recently bought one which worked like a charm the first time I used it (to identify an AMIBOOT.ROM issue with an AMI BIOS). The second time I went to use it (for a different issue with a different computer), the fault codes it gave don't make alot of sense to me. The one in particular is '81 -- late POST device initialization'. The unit came with a small manual, which lists all the POST codes and their "meanings"... but it's not making a whole bunch of sense, they're wicked generic. Does anybody know where I could find interpretations of the codes, or even some better instructions on how this thing works? Thanks.

 

Okay from what I can gather 81 is something to do with the keyboard, do you have a spare you can swap over?:

Sorry... I should have mentioned, it's a Pheonix BIOS. I think 81 is a keyboard error for AMI
