Comment 3 Robert Moore 2006-02-17 12:57:24 UTC 
It looks like the table checksum for OEMB is indeed incorrect. It is 0x31 and 
I calculate 0x30 from the dumped table data.

The error message is a bit terse:
  >>> ERROR: Invalid checksum

It should display the bad checksum and the computed checksum, as well as the 
action taken -- ignoring table, ignoring error, etc.
Comment 4 Oleksij Rempel (fishor) 2006-08-03 08:45:11 UTC 
Fixed with BIOS version 803 07.07.2006.
