dr dos 7 was supposed to be 32bit. at the very least it had 32bit protected mode, pre-emtive multitasking. not sure how deep the '32bit' ran though (ie, if it went to the kernal or was just their emm386 implementation). i just remember it being a great os for running games at the time because it was pretty easy to setup games to have plenty of high and low memory.

my own memory is very fuzzy on the details though...

Distributed Reflection Denial of Service

Why do the names of these service-denial attacks tend to coincide with the names of 16-bit embedded PC operating systems? For example, the generic term "DoS" (denial of service) collides with "DOS" (disk operating system). The term "DRDoS" (distributed reflection denial of service) looks like "DR DOS" (Digital Research disk operating system).

Unsupported, but you can still buy it in 5 or 10-license packs, and still download a non-commercial use only version from Club DR-DOS (actually Lineo, but yano). Supposedly comes with the web browser and some spiffy source code.

How do u get [bochs] to emulate ps2???

First of all, it won't work with PS2 titles released in 2000 or later because those titles are designed for a different platform: Sony PlayStation 2. Bochs emulates IBM Personal System 2; many PS/2 titles released before 1994 work in Bochs. However, there are still thousands of titles on abandonware sites such as this that run on IBM PS/2.

Once you know you have an IBM title and not a Sony title, just read the Bochs manual to learn how to install DR DOS or FreeDOS and then read the game's manual to learn how to install it to Bochs's virtual drive.

For starters, it's 9x that hold all the legacy code that is supposed to make DOS programs work. The whole *point* of 9x is to move DOS style applications to NT style applications. I think that MS would've been overjoyed if it could've dumped DOS & 9x all together long ago, it has a far superior product in its hands (NT).

So why is Microsoft charging twice as much for NT as for 9x? And why couldn't they have just done more work in the DOS virtualization department? For example, Windows 2000's VDM chokes on 32-bit programs that conform to the DPMI spec.

I'm not sure if Linux is suffering from the same problem (having to maitain compatability with legacy code, so you can't solve problems the most efficent way)

Linux has a legacy (POSIX; Single UNIX Spec; X11) but it's a quite well-designed legacy. DOS is nice as an embedded OS, but anything complex is ugly.

DR DOS is a $39 shareware clone of DOS. FreeDOS is a GPL'd clone of DOS with a few bugs (e.g. it irreparably corrupts any drive larger than 512 MB).

DR DOS.com and DR DOS.org have more information on DR DOS.

XGNOME vs. KDE: the game!

Microsoft has already abandoned DOS totally

But the embedded market hasn't. Neither have these guys. And the FreeDOS Project is even creating a GPL'd DOS clone.

What if your hd is formatted FAT32? AFAIK, DR DOS won't be able to read it.

XGNOME vs. KDE: the game!

Microsoft QDOS (Quick and Dirty Operating System; no, really) is dead (Win2k; Whistler). Lineo and the free software community make two DOS operating systems now. IBM also makes its own PC DOS 2000.
