[LinuxBIOS] Xvesa on LinuxBIOS

Hi Ron,

yes, I think it is a good idea too although some friends said me it is
a crazy idea :)

A way to you replicate this problem is: start LinuxBIOS with video
support (from original VGA ROM BIOS), then run kdrive (Xvesa) or even
try to start XFree with Driver "vesa" in Device Section of XF86Config
or xorg.conf. I am using Tyan s2850 with onboard ATI Rage XL.

The Xvesa assuption is just to find the interrupt vector pointing to
some area inside the 0xC000 segment,  but I don't figure out it. I am
not an X server and kdrive expert, maybe Keith Packard can answer it.

Finally I get sucess to start X11 inside LinuxBIOS, I make a work
around just "hard coding" the right segment and offset in vm86.c.

After I will record a video and place in youtube to others people see
it. I hope we can create something like the Phoenix BIOS to read email
and browser web.

Please make the video available in the free software Ogg/Theora format too :-)

Check out vixy.net for transcoding FLV, it doesn't do open formats
but there are other tools for that. The MPEG4 quality is very nice
since it does not fully decode FLV before encoding MPEG4.

Ok, no problem.

Just now the graphic mode still very simple, it just has Xvesa running
with Matchbox and rxvt. It starts in ~ 8s, but I have some ideas to
improve speed.

Other problem is the space, the 2MB BIOS flash is completely full, I
removed almost everything from kernel, including printk support. I
will apply the LZMA patch in kernel, maybe I will get more space.

Yes it is fantastic, all we need inside a BIOS.

Somewhere, a deity has just killed a kitten.

It's an interesting idea, though. If things need to be done this way, there
ought to at least be a free alternative to the EFI approach.

LinuxBIOS has builtin LZMA support which saves you ~30-50kb over
the LZMA kernel patch. Simply lzma the right vmlinux file.
