DOS ain't dead

Old NX-DOS boot help request (Miscellaneous)

I tested various disk images that I found in the archive you posted. The first two after booting test COM and LPT ports (which I no longer have) displaying terrible messages in the form of a string of numbers. Then the system freezes. Another after booting displays "SYSTEM HALTED" and waits for [R]estart to be pressed. The system in the last image boots up fine and waits for a command to be entered (only a few commands are available) after which it hangs because there is a video memory address in the stack that it jumps to after executing the RET instruction. I managed to fix it, but I can't tell if it will work. I used my debugger (Dark Debugger) to trace the boot process. I am sending you images of disks that work relatively well for me. IMHO the NX-DOS system is very unstable and there is nothing to play with it. Also, it doesn't (probably) support FAT32 drives.
