Hi!
I was just wondering if it's possible to use linuxbios as a kind of virtualisation machine, meaning that I could use linuxbios to snoop windows drivers for register hunting (to get real 3D-gfx-support for instance)? This means that windows would run as a virtual os.
Best regards

Not really. LinuxBIOS is pretty much for booting live hardware. What I think you wan't is the bochs project, VMware or Win4lin.

Well, if snooping is going to work the windows drivers has to talk to the hardware, which vmware & bochs doesn't support. I'm not saying that linuxbios could do it today but was merely asking if it was theoretically possible. Afaicu, when linuxbios (or any bios for that matter) has started the operating system it doesn't run anymore since it basic functions are fullfilled (hardware setup & loading of os). A virtualisation machine much like vmware or bochs, except that this machine would let the operating run on the hardware instead of emulating the hardware (am I making sense?).

So you mean some sort of HAL like the VM on a IBM370 does.
Possible but linuxBIOS is a _long_ way from that. And it's not really compatible with its overall goal which is to get the hardware up enough that a linux kernel can take over. Load a payload into ram and jump to that.
The qemu is a target in V2 if you start working with that you may be able to do what you want.

Yes.

I know. But isn't one of linuxBIOS goal to have a stable, remote configurable bios for use in clusters? Wouldn't a vm (or hal if you will) be even more useful than a Basic Input Output System?

Yes, it looks interesting...
Thanks for the input!

I don't do any clusters so I can't really speak much for thier needs but I think the linux kernel provides all the functionality they need and much more.
The big problem is keeping up with hardware support. It's hard enough as it is to keep up with just the functionality of the chipsets we try to support now.

that's the job for xen, not LinuBIOS

I think you want a true emulator for this, did you look at qemu?

Yep, got a pointer from R.Smith. Thanks!
