You should modify a COPY of SK.COM with DEBUG by entering the following commands: you enter: DEBUG SK.COM A 089E DEBUG responds with: XXXX:089E you enter: NOP DEBUG responds with: XXXX:089F you enter: NOP DEBUG responds with: XXXX:08A0 you enter: A 08AD DEBUG responds with: XXXX:08AD you enter: OR AL,01 DEBUG responds with: XXXX:08AF you enter: W Q That's it!
