> PCI ids will be different Oh - what do you mean by the Sean?
I am still trying to understand why for two identical CPUID/Stepping E3815s, with the same 8BM flash image, I get different PCI device ids for the Soc Transaction Router ( 0000 rather than 0f00 ) and Video ( 0031 rather than 0f00 ). Is this related? I’ve asked Intel Premier Support but heard nothing back yet. Still puzzled :o) Mike.

The TXE from the BIOS’s you mentioned don’t work with coreboot. I ran into the same issue as you. Alternatively you can erase the top 6MB to start in non-descriptor mode. I don’t think this matters much for coreboot’s startup process, but could be wrong.

I also thought it was working better for me too as I was observing coreboot and fsp booting until it failed at SeaBIOS. It turned out I had a pilot error flashing the image. I thought I flashed the top 2M of the flash, but my script accidentally erased the bottom 6M. Surprisingly it booted quite far. Anyhow, after I corrected my script today (flashing only the top 2M, leaving rest from BIOS). Nothing happens, port 80 remains 0, no console output.

We have a Bayley Bay CRB (E3827, B3). With coreboot Baytrail fsp support pulled from about two weeks ago and some help from Martin, I was able to see coreboot booting and fsp loaded, but was having issues with SeaBIOS. I pulled latest source tree this morning and found out it does not boot any more on my board. Port 80 stuck at code 0x43, no console output. Here are my steps: 1. Build coreboot toolchain. 2. Build coreboot.rom using fsp and microcode from BAY_TRAIL_FSP_KIT downloaded from Intel fsp site. 3. Flash coreboot.rom to top 2M of the 8M flash. I was getting the usage information here and there from the discussion threads and perhaps I missed something? It would be great if somebody could post the detailed procedure. Thanks!
