It's possible that the CPU has changed in later Pocket386 models? I just booted my Pocket386 .. it's running a standard install of FreeDOS 1.4, but I've commented out the networking stuff and the CD-ROM stuff in FDAUTO.BAT. The FDCONFIG.SYS is unmodified. And I get the full memory on the system, 8MB. No crashes. _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
