Except Mac CDs aren't ISO-9600 format, but Executor can read them. I've tried a Mac CD-ROM that DOS 6.22 and Windows 95 *cannot* read but Executor can. The same should hold true for Mac formatted hard drives. (i.e. They can't be seen from DOS or Windows 95 but can be seen from Executor.) > obviously, a DOS executable on a CD-ROM will not work on a Mac and > vice-versa... I don't think the vice-versa is true. I've run Mac programs directly off a Mac CD-ROM in Executor. > i don't know how executor reads the floppy drive directly, but they must > do something, esp under linux, since i can't even mount a Mac floppy. Exactly. Executor can read the binary format of Mac media (e.g. floppies, CD-ROMs, and hard drives) that otherwise can't be seen from the DOS/Win machine. Any clarification from ARDI? --- Stephen Su ssu@garnet.berkeley.edu
