Just to clarify, I want to not even be able to upgrade the BIOS. The machine can't tell if I'm actually sitting there trying to push new code into the ROM or if some malware is doing it, so I want the machine to refuse any request.
Okay, maybe a hardware switch on the motherboard wired to the write-protect pin, but that begs the question of why that write-protect pin is needed. (Another comment expresses why which I'll respond to separately.)
- userbinator 6y agoOkay, maybe a hardware switch on the motherboard wired to the write-protect pin, but that begs the question of why that write-protect pin is needed. For a period in the late 90s and early 2000s, there was a physical write-protect. That was also a period when BIOSes came with less bugs, so there was far less need to change it; but when the need did arise, it was there.
