The Intel 80376 was an x86 CPU that didn't support Real Mode or paging. It was targeted for embedded applications and it wasn't very successful at that (the 80386EX overtook it).
Under these conditions, it seems hard to believe someone could ever use it to build a PC compatible. Yet BIOS function
INT 0x15, AH=0xC9 (included in some IBM PS/2 computers), which is supposed to detect the CPU type, seems to have a code (
0x33) saved for the "Intel i376".
This raises a number of questions:
- Was there any PC using the i376 as its CPU?
- If yes, how did it remain backwards compatible, since the i376 doesn't support Real Mode?
- If no, why did the BIOS authors reserve such a code for a CPU clearly targetted towards a different market?
