I see your using an ISA adapter. One of the first things to complain in a low heat producing system like a 486-66 is the controller card. You don't say what the 'problems' were, but if they seemed to happen only some of the time, I would suspect heat. Clean inside and check the fans. I would also clean the adapter card's edge with a pencil eraser. The card you mention is a servicable replacement if you really need a new adapter.

She said she started having "problems" running programs last week. Then yesterday upon booting she received the message on booting "FDD controller failure" and "HDD controller Failure" "Press F1 to resume". Natch, she can't boot. I assume that means that the controller card has taken a dump. Am I correct in this long distance diagnosis? Is this as simple as pulling the old controller card and plugging in a new one? Well, that and blowing out about ten pounds of cat hair. I found a SIIG Fast EIDE card http://www.siig.com/ide/eide_master_isa___io.html at the local Fry's and it looks like what I need. Am I on the right track? Of course this comes as grad school mid-terms are due.
