In the s2891 tutorial it shows phnxdeco producing a rom.scr file, which the readme says will reassemble the BIOS. The version I downloaded doesn't seem to produce this file with the -xs or -x options.
What's the preferred way to get the BIOS out of the .wph file so that flashrom can use it?
Thanks, Myles

IIRC the ROM is at the beginning or the end of the WPH file. Simply compare it with your current ROM, find the matching area, then use dd.

Since my current ROM is coreboot, that won't work, but I guess I could try 1MB sections until I find the right one.

Ah sorry, I overlooked that. The last 16 bytes of the correct image should look similar to what coreboot has there. Well, not completely, but the jump instruction at 0xfffffff0 should be there.
