[LinuxBIOS] IWILL DK8-HTX

[Philipp Degler]

Hi greg,

coming back on your thread-entry. We would like to get the 
IWILL DK8-HTX Rev. 1.0 running. Is it possible to use devbios 
or mtd to access the bios or is the hardware flash programmer
the only possible (better) way?

The board uses an AMIbios, SVR 2000, AA46 (6827) with the following
layout:

(x7)

    -		     -    (x9)
    -		     -
    -		     -
    -		     -

      ,  ,  ,  ,  ,  ,  ,

What hardware flash programmer would you suggest to get started?

thx a lot

To give reliable advice it would be good to know the flash part
number of this PLCC32 chip. Try gently peeling off the AMIbios
sticker to see a logo and model number on the black plastic part
itself.

we generally use those holographic bios labels for more picturesque 
uses, such as those electronic valves you see on toilets nowadays. Looks 
nice.

Is your bios chip in a socket, ie. can it be removed with a chip gripper?

Use flashbios from the LinuxBIOS source tree (util/...)

devbios is obsolete, I will put further development into flashbios
instead.

You might find the bios savior useful. Generally most hw flash
programmers are pretty expensive if they're supposed to work for more
than a chip type.

You need to find out what flash chip you have (ie. look at the ID
beneath the AMI sticker. It's probably an SST49LF040)

Cheapest and quickest solution is to get a backup chip and and exchange
the AMI chip after booting the system to burn the new one.

to start, for a test, get linuxbios v2 on your node, build flashrom, and 
run it with no arguments. If it prints out the flash type, you're in 
pretty good shape to start.
