When you are in native CBM-II mode all you see are the two PRG files, BOOTMS.PRG and MSDOS.PRG. Is the entire MS DOS in MSDOS.PRG? BOOTMS.PRG I suppose sets up the environment. Does what I am asking make sense?Has anyone here taken the D80 file and made a bootable disk? Yes (I have the system packed away at the moment, but I am getting itchy to test it out given the on-topic-edness. When I got the disk from Bruce Feirson, he told me he just copied the disk using COPY 1 to 0. If there is no other way I will make a copy of this disk for anyone who wants one. I also have a few versions of CP/M-86 and a Z80 emulator. My 8088 is flakey at best, sometimes works, sometimes does not. I have to stand on one foot sometimes with my hand on my head to get it to work. Bill Message was sent through the cbm-hackers mailing listReceived on 2011-01-17 18:00:19
