Support for Boser crusoe board?

[Hubert Denkmair]

Hello list,

I have a very, VERY nice mini PC with Crusoe TM5400 / VIA VT82C686A 
chipset here:

http://www.boser.com.tw/products/sbc/hs1600.htm

Linux works fine on it, now it would be cool if it was supported by 
linuxbios. There seems to be support for the vt82c686 (without 'A') in 
the v1 source tree, but of course there is no direct support for the 
Boser board.

Are there chances that this board will work with linuxbios?
If yes, what do I have to do to get it working?

transmeta have really improved and the docs you need are online or at 
least available. Contact transmeta for info.

There is no support for Transmeta based systems in LinuxBIOS yet, but
from what I heard, they hardcode memory values for the first little
blocks so you already have ram available when you initialize the whole
amount of ram. Otoh, it might be tricky to get the code morphing stuff
right without Transmeta's IP.

Does anyone have Transmeta's datasheets or some clue how hard it would
be to get this done?

I have them, but by the time Transmeta got around to making them available
the interest level here had died down to zero. The morphing issue didn't 
really come up at the bios level. I still think it would be nice to have a 
port, we just don't have the cycles here.

I think there is a new transmeta cpu and possibly the effort should be put 
into that, not sure.
