i thought it was ram, but it's not.
i can't convince myself that there's a short in the board.
the machine exhibits unusual network behaviour (despite being air-gapped), and there are symptoms of a "bios virus" that seems like a government attack. it has frequently randomly installed netbios, using a process i don't understand. i've wondered if somebody is utilizing a hidden wifi chip, or hacking me using microwave technology.
until recently, ps/2 functionality repeatedly disappeared. i seem to have solved that with repeated bios flashes.
i think it's hardware.
but, the bottom line is that i can't figure it out, and i need very careful testing, as a result of it. i have to organize my data in a specific way before i can get back to what i was doing, but i'm going overboard on organizing it and calling it "filing" in an attempt to test the machine by using it.
i've stripped everything down and/or turned everything in the bios off, except
- video card (nvidia card manufactured in the mid 00s. there is no card on this board, otherwise i'd just use it. i'm not very concerned about video quality.)
- external pc sound card (maudio delta 1414 that i bought at a discontinuation sale for the rca dacs)
- one dvd reader/writer
- floppy drive
- four sata hard drives
- usb functionality is the only thing running via the bios
it's running as a single core, for example. no firewire. nothing.
i can only hope that's stable.
i didn't change anything in my install scripts, so i don't know why it would be software....
