Yeah supposedly this is TCL code that works with the FS2 and will do
things like read and write MSR's and some other stuff.

I've been playing around on and off for the last few years with these
8363 thin clients made by IBM. They are really brilliant machines and
are powerful enough to use either diskless (running local apps via NFS),
as thin clients, or as standalone devices (CF).
They are also x86 (Cyrix chipset) with a Geode VGA. They have VGA out,
sound out, mic in, 2 USB and a NIC. It also has a built in CF card that
is seen as hda when used.
More info can be found here:
However an issue with them is that the bios that is supplied with them
is annoying to say the least. It does not support any boot loaders
(lilo/grup etc...) but instead loads up an elf uncompressed kernel. For
reasons I'm not yet sure, the kernel (2.4) needs to be compiled by gcc
2.95, and requires various patches to get it to work. I've never got 2.6
working, and never got even 2.4 working with a compiler other than gcc 2.95.
However, with the old kernel, I've gotten a pile of these going and they
are fantastic. They can play mp3's, play video, and as I test I setup 20
of them with distcc and used them to assist in compiles. Also they are
extremely low voltage and could possibly run in a car from the cigarette
I believe that this device is a perfect candidate for LinuxBios. You can
pick them up dirt cheap (~$10) from ebay, and in fact there are LOTS of
these just floating around, and a decent bios that will allow one the
flexibility of loading a newer kernel would be great. You can run them
diskless as I mentioned before or can install to CF, with the CF seen as
The bios is a 32ping socketed PLCC AM29F040B.
I was wondering if anyone has tried LinuxBios on this and what the
results were? Would anyone be willing to get it going? I would be happy
to package one of these up, with a working linux distro on its internal
CF and mail it (to keep) if it would help. Ideally it would be great if
it was possible to be able to boot via NFS (PXE would be brilliant) and
also have the option of direct from the internal CF.

bad news! flash write enable is not working! :-(
In the datasheet said pins TBL# (pin 8) and WP# (7) need go to high to
enable flash erasing/writing, but enable_flash_write() on vt8235 is
not activating it (I verifyied these pins using oscilloscope).
Then enable_flash_write from vt8235 is not working on vt8237!

Sure, but I think the problem is because enable_flash_write() is not
unprotecting flash (at hardware) to erase.
Another idea to solve it?

The VSA2 bios for OLPC seems to be quite minimal: 64 KB.
I would be glad to know:
- is there only vsainit and sysmgr inside vsa for olpc?
- does audio, ohci/ehci and video handled by kernel drivers?
- does OLPC target booting without major problems?
It seems to be true but it is better to know for sure ;)
I read a thread about getting linuxbios work on the PC-Chips M810LR
from Antony Stone:
My question is, if there are any newer boards from pc-chips which are
Or are there any other boards like these ones (the opteron boards of tyan
are too large for me, i would prefer micro atx), because I only find
old boards, or the huge ones of tyan.
In another thread I read about the win-ent mb06047/48/49. These boards would
be definitely too expensive for me.
Many thanks in advance,
It is using NVIDIA nForce3 250.
You'd better to find one with Nvidia Nforce 4 or Ck804.

Subject: [LinuxBIOS] ASUS K8N
I run a search on the mailing list, but found no mention of it: does
anybody know if the ASUS K8N (without any qualifiers like Deluxe or so)
will work with linuxbios?
Thank you in advance.

I was just trying to understand the code flow of LinuxBIOS on x86
architecture. I understood that on a power on (cold boot), there is a wait
for power good.
Later there is a transition from real mode to protected mode (32 bit).
The file that makes the transition is entry32.inc of src/cpu/x86/32bit
After this point I was not able to make able to make much progress as to
which part of the code is executed.
Any help in this regard will be helpful.
I did check through the available documentation in documentation directory
of the source tree, but
would appreciate if there are any pointers at the code level.
