The current dec alpha emulation can't run the SRM or ARC bios.. it's a long way away from being able to run any OS, let alone NT.

Have you tried Windows 2000 for Alpha with Qemu?

crashing is probably not a problem, because you won't need the yellow window anyway: qemu graphic card is not supported by the standard bios.

I mentioned some images here:

I just noticed that I'd need a Sparc ROM for this to go anywhere..... (beyond the windows version crashing...)...

I don't suppose you'd have any leads on obtaining it?

It just makes me wish I made rom images of all the machines I've owned over the years....

Never built it under windows, so just don't know. Under linux I use 4.4.1.

But, I'd say the problem now is not the gcc. Have you tried it without a hda option?

If it works then you just need another bios (only the versions from SPARCstation-5 are known to work). Take a look in my how-to:

It'll be a bigger deal when people see SPARC Solaris running on a laptop.... that doesn't cost a fortune....

Although sad news on the windows front, it just crashes before showing anything......

C:\msys\1.0\src\qemu\sparc-softmmu>qemu-system-sparc.exe -L ..\pc-bios -hda \tem
p\disk.qcow

It opens a yellow window, then crashes... Nothing is printed to the stderr, although that may be an artifact of it crashing :|

What version of GCC are you using to build? I'm wondering if it may finally be time to say goodbye to 3.4.5

Preferably older than 2.4 and newer than 1.1.2, those are already tested. :)

Glad you see it as a big deal. I had to find/fix bugs in a scsi controller, scsi disk, mmu, interrupt controller and cpu to get this far.

Funny enough none of this bugs was preventing linux/sparc from working. :)

WOW that's a big deal....

NeXTSTEP/OPENStep's 'text mode' was in fact graphical....

Although the solaris thing is big too!!!

I'll certainly have to fish around for some sparc solaris stuff, I hope I still have my old SUNOS CD...

It is capable of booting Solaris 2.4-2.6 and the kernel of 7. I wrote some sort of a how-to in my blog.

Both qemu-sparc and the how-to are far from being perfect though and reports/comments are welcome.

NeXTStep requires a better graphic card than qemu emulates. Don't know whether it would run in a text-only mode.
