Hi,
Im new to the list and I read some about coreboot and im impressed. I would like to make my elite C7VCM VIA CN700 & VT8237R Plus Chipsets C7 CPU Onboard (http://www.ecs.com.tw/ECSWebSite/Products/ProductsDetailPhoto.aspx?DetailID=...) boot with first lilo and then later on etherboot. I got the version 1.2 with 12v supply. This board is really cheap under 80 dollar and it is for a kiosk project. Since the orignal bios award bios 6.0 do not work with usbboot (in this fork ofcourse) which I need I hope I can use coreboot
So what do I need to do? As I understand the CN700 & VT8237R Plus are supported as well as usbboot with lilo. To add a board as I can see I need to adapt the config.lb in target and add and adapt the board in coreboot*/src/mainboard/. Is it something else I need to change/adapt/add in coreboot? I might get a problem with VT8237R Plus since its VT8237R in the source, whats the difference? The bios chip is a sst49LF040B and I can not hot flash it on this board so I ordered a "enhanced willem pcb5.5c universal programmer". Is there a linux software I can use with this burner?
Here are the lspci and lspci-vvvxxx
and all help is appreciated

The cn700 support is nearly complete. Check back in a couple of weeks. The vt8237r is also supported.
The current version of Flashrom should be able to program your sst flash while in your board.
What problem did you have with your attempt at reprogramming your flash while it was still on the board?

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.

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.

Thanks for testing!
Writing fails.
This may be because the chip was not erased before writing?

Hm - this error message is not in the flashrom write code path?
Please check if erasing the flash chip (with -E) works. The most reliable way is to erase, then read back into a file and run hexdump on the file.

It could be that I didnt install flashrom from source. I run suse 10.3 on this mashine.
I will download the latest version and compile it and test.
