1G operation of 82599

We have a design using the 82599 that has errors such that we can only

use one lane is each direction.  As we would like to test as much of the

design as possible before doing the revision, are there EEPROM files

available that allow 1G SERDES operation on lane 0 of the 82599?  I couldn't

find any in Rev 4.25 version of 82599_EEPROM.zip

Thanks, Paul.
