thanks for your reply. i thought
src/northbridge/intel/i945/early_init.c is executed after stage1_main
somewhere in real main. i've put a lot of postcodes bevor that
- one in front of stage1_main and and one in real_main. shouldn't i see these?
in my understanding execution takes the following way:
1 some generic x86 startup assembler
3 cache_as_ram_disable.inc (stage1_main)
4 romstage.c (real_main) in mainboard dir
isn't that right? it looks like i hang between 2 und 3.
i'll go and check the toolschain in utils.

i also tried with a 1 meg fhw with a somewhat earlier version of

Did you adapt the code for your SuperIO chip? Do you get any messages on
the serial port?

Try this one:
--- src/northbridge/intel/i945/early_init.c (revision 5196)
+++ src/northbridge/intel/i945/early_init.c (working copy)

+ //RCBA32(GCS) &= (~0x04);
/* Just do it that way */
RCBA32(0x2010) |= (1 << 10);
Then post codes keep going to PCI instead of LPC and you should see
where it's going.

You should use the reference toolchain in util/crossgcc
