Do you have a null-modem cable?  Did you see anything on the serial console?

The siren is the chipset complaining that its timer wasn't touched for
too long.  That sounds like an early problem.

I don't know where there's a list of them, but if you grep the source

What size is your coreboot.rom (ls -l)?  What size is your chip?
That's a frequent problem.  If you had to add another ROM, did you

Have you tried it with a warm reset?  It's a bit of a long shot, but
it can affect things sometimes.

worried about that, use buildrom to build a payload.  Grub2 from
buildrom works well as long as you substitute ata for hd in the
