Does it mean Bob Harp invented the BIOS?
- mhurron 11y agoWikipedia has the term BIOS being used in the way we expect by CP/M in 1975, the article has Vector starting in 1976 and the PROM board created after their memory board saw success. It sounds like he brought the BIOS to S-100 bus machines though.
- mark-r 11y agoCP/M hardly ran on anything but S-100 bus machines in the beginning. It was common in those days to compile the BIOS directly into your copy of CP/M, rather than running it from ROM. CP/M had memory areas set aside that you could patch. The ROM was only expected to contain a boot loader that would copy the OS image into memory and jump to it.
