Hello,
I tried what you said and I can see the following:
<snip>
6: 00000000ff000000 - 0000000100000000 = 2 RESERVED a b c d addr=0x00007000 len=89000
coreboot-4.0-1929-g79cfe7e-dirty Thu Jan 5 17:41:55 CET 2012 starting...
</snip>
Debug level of SeaBIOS is set to 10.
How can we guess which thing is causing the problem?
Thank you.
Best regards,
Elisenda

Well, since you saw "d", but not "Jump to int19" it would indicate that it died in the memcpy (I assume your debug level was set to something higher than 3). That's really strange - I don't know why it would halt there. You could change the first dprintf to read something like:
dprintf(1, "d addr=%p len=%x\n", (void*)BUILD_STACK_ADDR, BUILD_EBDA_MINIMUM - BUILD_STACK_ADDR);
If the output makes sense (it should report 0x7000 and 0x89000) and it is really halting in the memset, then maybe coreboot is mapping something into the first 1 meg of ram - though that's just a wild guess.
