6bc1738bfd pcat: implement (loop)
8086 asm is a lot terser than z80... Those indirect memory operations
are very handy.

d8d2e05eb2 pcat: make find compare strings
find is the biggest chunk of logic of the boot code. The 8086 version
is significantly terser than the z80 one. REP/CMPS helps...

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!
