Hi,

I have been testing this patch on my Soyo SY-6BA+ III, i440BX based.

Good news:
128MB module on its own in any of the 4 slots works.
256MB module works (tested in one slot).
128MB + 128MB works.

Not so good:
128MB + 128MB + 256MB + 128MB boots but only with 512MB RAM. Should add 
up to 640MB. If this is a limitation of the chipset that's fine, but 
maybe it could print a warning message if that is the case?
A single 16MB module did not boot. Log:

But in all that's a very good result, thanks for the work and the patch! 
Now I'm not sure what else I need the vendor BIOS for... :)
