Virgil Dupras	8c452f5add	pcat: begin implementing find Not comparing strings yet. Without asm tooling support, it's a big chunk to swallow at once. It's progressing well!	преди 4 години

Virgil Dupras	1a467efae1	pcat: use a far jump to boot into the OS Unless I misunderstood, this is supposed to set CS. This would make all SREG have the same value. This allows us to remove BIN( offset from os.bin. I've tried booting to offset 0, but it didn't seem to work. Let's settle for 0x8000. 512kb of system RAM is way more than we need anyways.	преди 4 години
