Hi,
I was wondering if the Jetway J7F4K1G2E board is supported by coreboot. The hardware seems very similar to VIA boards.
It has the following specs (from http://www.jetwaycomputer.com/spec/J7F4K1G2E.pdf): CPU: VIA Eden 1.2 GHz Core Clock CPU and Low Voltage Edition Chipset: VIA CN700 North Bridge Chipset + VT 8237RP South Bridge Chipset Ethernet: Dual Realtek RTL8110SC 10 / 100 / 1000 PCI LAN PHY
Not sure if the rest of the specs are interesting...
Is there a chance it'll work on this board?
Kind regards, Richard Stellingwerff.

Not at present.

Corey has added support for C7+CN700 but I think he still wants to add some finishing touches to that code.
VT 8237RP South Bridge Chipset
8237RP - now what is that?
Rudolf has received the 8237R data sheet from VIA and I believe he is working on adding support for it to coreboot. I don't know if that will work for 8237RP as well.
Ethernet: Dual Realtek RTL8110SC 10 / 100 / 1000 PCI LAN PHY
Should not matter much with regard to coreboot.

SuperIO chip and flash chip is also interesting. Is there a high-resolution photo of the board somewhere? ("Award 4MB Flash ROM" in the PDF does not say enough.)

It won't work out of the box right now I'm afraid. Once 8237R support is in the tree you could start experimenting with the board. It might come up on the first try. :)

Could be the VT8237R Plus (hence the P), but I'm not sure.

VT8237R is already in svn, but the CN700 is not yet.
It would also be interesting if the ROM chips is PLCC or SPI, and if it's in a socket or soldered onto the board.

It's socketed. Here's a picture (sorry for the lousy angle and low resolution, it's the best I could find): http://www.picco.nl/images/A32624.jpg
I don't know if it's SPI or PLCC yet.

It is a PLCC package in that photo.
Probably connected on LPC, there's no point in using SPI for PLCC chips. I don't know if such chips even exist.

VT8237R Plus is LPC (also supports FWH mode) but not SPI. SPI is only on the VT8237S.

CN700 is in svn. Urbez has a patch for the CN700 that has not yet made it into svn.
Your board is similar to the Epia CN10000 that Urbez has working and the EPIA LN and VT I'm finishing up. Corey has a Jetway with the same combination of CN700 + 8237r that works.
You may need to get an ACPI table and work on int. routing.

Okay, that is good to know. This ACPI table, is it something I have to request from Jetway, or is there another way to get it?
Unfortunately I do not have this board yet, but I'm expecting it by the end of this week, so I can't try anything until then.

You can get it from the factory BIOS. Take a look at the Epia M build tutorial:
