Let me summarize the issue with the m57sli-s4 and the bios savior:

1. flashrom *works fine* if you don't use a bios savior. Read and write. See

2. flashrom *works fine* if you plug in a bios savior and set the switch to
'ORG', meaning you flash the chip you plug into the bios savior - tested with
ST parts (including the original part that Richard Smith desoldered from our
board for us).

3. flashrom can't see the pm49fl004 part that's built into the bios savior.
The board will also not boot if you switch the savior to RD1 (which is that
part) after writing the correct image into the bios savior on a different
machine. The bios savior works fine in our tyan-based systems.

I hope that clarifies everything!
