Note…

Remote “emulator” does not support direct access to the screen memory. Such popular software

as Norton Commander will not work properly with remote video console, and the picture will be

visible only on the remote computer screen.

Floppy Disk: INT 13

When the remote floppy disk is enabled, all floppy disk requests will be redirected to the remote con-

sole application; all requests to the hard disk will be executed by native BIOS.

To make the “remote floppy disk” bootable, it’s necessary to make a floppy image from a bootable

floppy disk.
