re: Boot analysis from PCI



Michel,
  I have to say that if the BIOS was not developed for the specific board 
you are using, your chances of it coming up are very slim.  I'm not sure 
which BIOS you received, however if it was for an Intel sample board, that 
is a different division of Intel than the makers of the MARL board. I would 
expect  MARL to have considerable customizations from the sample to make 
the sample BIOS unusable, except to a BIOS developer.

We've tried to put an Phoenix Evaluation BIOS (for 430HX chipset) on an
Intel MARL board (which is normally delivered with an AMI BIOS).
With this BIOS, the mother board does not boot.
On a PCI analyser, we observe the following sequence :

I'm not very familiar with boot code but it seems that there is a problem
with I/O Read at address 52C-52D.
According to Phoenix, their BIOS has been tested on an Intel Board which
was not a MARL board but it should run on MARL.

Does somebody know if there is hardware differences between original Intel
platform and MARL Mother board ?
Any comments concerning this problem would be wellcome.

Michel
