How does freedos handle newer hardware? I remember giving up on my super DOS boot disc about a decade+ ago when it wouldn't boot anymore. If memory serves it was around the end of IDE drives, but I could be wrong. Maybe it had to do with EFI.

Curious. How exactly does one build embedded applications for FreeDOS? What languages/compiles can I use?

Rexx! Loved that on OS/2, pretty happy to see that it has a home on FreeDOS.

FreeDOS, like MSDOS, relies on BIOS calls to control the hardware. Most PCs aren't pure EFI-only and can still boot with some BIOS compatibility, but of course not all of the BIOS implementations are bug-free.

When legacy BIOS compatibility is truly dead, I guess DOS will die with it.

What can I do that is moderately interesting with freedos? I've downloaded it a couple of times, but I never found anything useful to do with it. I'm sure I could play some games, or something. I really want to actually learn it.

I legitimately needed to use freeDOS a few months ago in order to downgrade the firmware on my BluRay drive, so I'd be able to rip 4K discs. It could only be done from DOS.

Unless you want to work specifically with FreeDOS, you might look at DOSBox instead. It's a MS-DOS emulator that runs in user space, rather than running as the OS, thus a lower barrier to entry.

You can compute like a PC user in the 1980s. There are various word processors, database utilities, and programming languages available. There are even old school networking tools for newsreading, IRC, telnet, and gopher.

I remember "DOS for Dummies" (the seminal Dummies book) being helpful when I was starting out; you can probably find a used copy for the cost of shipping at this point.

Might lead to more practical possibilities, too. Like in this unexpected story:

The utilities provided by FreeDOS are generally more complete than those provided by DOSBox. You can copy them into your DOSBox installation for the best of both worlds.

I remember using FreeDOS for learning assembly through the `debug` command. Looking at the BIOS data was fun for me at the time. I've also tried DOSBox but since it's emulated the BIOS data wasn't "real".

I have not yet found an equivalent of the `debug` command for Linux. Ppl told me `gdb` could do the same but I found debug easier to use.
