 		 #154645 - FreeDOS?
Responding to: ???'s previous message
Russ Cooper said:
That actually sounds like an interesting project: Create a floppy or a CD that boots directly into a program that prints "Hello, fatso!" on the screen and then just hangs the computer. How hard could that be?

Then the next easier step from there might simply be to use some old version of DOS that doesn't even think about putting the CPU into protected mode. Of course it wouldn't have half the drivers you'd need to run a modern PC with all of its peripherals, but neither would you have those with the previous, lower-level ideas either.

For the record, I did find an old DOS diskette a little while ago and it did boot and run on my current semi-modern Pentium 4 machine.


Check out FreeDOS. It appears to be alive and maybe provide more functionality on the modern PCs than an old version of M$DOS.
