hi bari,
flashrom identify it as a VIA VT8237 but its a VIA VT8237R plus(well its atleast written on the chip). The bios chip is identified correctly.
Here I tried tor copy, verify and write the original bios. Writing fails.

Flashrom could not erase the chip and on a eites site they mentioned that you need a burner. The board does not have a jumper setting for flashing. I do not mind using a burner or another board.
So how about the the files under coreboot*/src/mainboard/ ? What do I have to do?
If you can get on IRC we may be able to help you work your way through flashrom: http://www.coreboot.org/IRC
Was flashrom able to identify your vt8237r and the SST flash device, but was unable to erase it?
There will be some additions to the SVN for the epia-cn very soon. It would be simpler for you to modify that code for your board (since it is very similar) and get it working first.
