Downside: it requires a serial port (though adding EHCI debug port support or something like that should be feasible - but "adding" requires some effort).
Aha... I did read about SerialICE, but didnt get anywhere because the laptop doesnt have serial ports. (and havent found one on the board, tho dmidecode names one) I'll get some flash chips and keep looking.
Area the minipci/minipcie diagnostic cards useful with coreboot/seabios ?
PS : Perhaps the vgarom doesnt work well because it is a PCIe card.
You won't see anything on VGA because the machine's RAM is not working. Which port did you use as a basis for a i965 port? i945? That one comes pretty close, but needs a _lot_ of changes, still, before it would come close to the point where you can start looking at enabling VGA..
Aha. However, lspci (and the specs) shows that my board is i945. 00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub (rev 03) (Mobile Intel® 945 PM Express Chipset + ICH7M)
If you want to experiment with supporting the i965 chipset, I suggest you do the following:
- Get a i965 based desktop board first and get that running.
- Get an Artec LPC Dongle/FlexyICE and a Stuge LPC/PLCC converter.

- Get a USB debug device for console via USB
Already have a programmer (lpc/fwh/etc) and think i have a i945 and a i965 board. Ill try to get the debug device, and try your suggestions.
