[LinuxBIOS] A question of Mptable

[Stephen.Kimball at bench.com]

I'd suggest you read about the IRQ and MP tables, then look at several examples in the LinuxBIOS source tree, then find someone who knows.  Running the mptable util doesn't give you much.

Yes:

1) Execute make in util/mptable
2) Run the mptable executable create in step 1 on the mainboard
   with the mainboard's original "COTS" BIOS installed.
3) The output of the mptable executable is an mptable.c that should
   saved as src/mainboard/<mb-vendor>/<mb-model>/mptable.c.

Some hand editing of the result of step 3 may be required.  Last time
I used it, I had to delete some non-C code at the end.  It was a
rather edit.

However, the resulting mptable will be a clone of the original at
best.  Any bugs in the original will be in the clone, but with
LinuxBIOS you have the option to fix those bugs.  Fixing an mptable
bug may not necessarily be easy though.

Good luck!
