that seems more likely to me than the buffer ICs.. if the buffers were bad wouldn't it also not pass ROM check?all symptoms says there is smth wrong with security part, you may try to disable RAM ICs as was suggested, but there is nothing can be done if 317-5064 itself has been died.
swapping the ROMs onto another IC seems to be the same amount of work as replacing the buffer IC as they're TSSOP with the same super fine pitch pins and traces.
on mine these chips use J-type pins that curl under the ic, seems I'd have to pull the whole pin out to "lift" it. Were your like this as well?Then I lifted pins 28 on both of the IDT 71v256s (they are just lifted off the board) and it fired right up. Try that and see if it works
They are located at IC44 and IC45. Im also running an H bios on this board.
yes, they are the J type pins and yes, you have to pry them out but you can do it between pin 27 and 28. Using a thin screwdriver between the legs and heating up 28 to get it off the board on both sides or you could use a pair of tweezersthat seems more likely to me than the buffer ICs.. if the buffers were bad wouldn't it also not pass ROM check?all symptoms says there is smth wrong with security part, you may try to disable RAM ICs as was suggested, but there is nothing can be done if 317-5064 itself has been died.
