NetBSD 4.0.1 (GENERIC) #137: Fri Dec 17 00:21:13 PST 2010

Welcome to NetBSD!

Terminal type is vt100.
We recommend creating a non-root account and using su(1) for root access.

It’s not very often you see any UNIX originating from Microsoft* (Yes I know .. Xenix) anyways it does boot, and to save anyone interested, I’ll spare you the 1.5 HOUR long install and give you my disk image.

Speaking of which, it’s SLOW. I mean S-L-O-W.

Also as a side note, here is how to mount a CD-ROM ISO image…

mount -t cd9660 /dev/ace1c /mnt

At any rate, the speed just isn’t there for any real usage.

Included is a bunch of stuff, like a basic x86 / cepc (with Windows CE 6.0 image), an Xbox 360 emulator, a SPOT emulator, some eval boards (AT91EB63?) with both MIPS and ARM cpus that even include a doom kernel like experience! A Macintosh G5 (I wonder if it’d boot with Apple ROMS..?) Oh and..

A VAX.

The VAX code is taken from SIMH but I guess to show how extensible the framework is, they mashed in enough microvax to get it going.

SIMH in a way you’ve never seen it…

At any rate, here is some other screen shots of Giano in action….

CEPC

xbox 360 alpha test

xbox360 console

And of course….

Giano MIPS doom

DOOM

Also buried in there is a new MIPS variant, the emips along with a donated NetBSD port!

Sadly I had no luck running NetBSD….

Maybe someone else will have better luck.

— edit, it seems Microsoft has a NetBSD 4.01 download, here. And it boots!
