(Fixed in Solaris 10 8/07.)

Solaris AMD x64 support includes a boot-time check for the presence of a BIOS workaround for the AMD Opteron Erratum 131. If Solaris detects that the workaround for Erratum 131 is needed but it is not yet implemented, Solaris logs and displays the following warning message:

WARNING: BIOS microcode patch for AMD Athlon(tm) 64/Opteron(tm) processor erratum 131 was not detected; updating your system’s BIOS to a version containing this microcode patch is HIGHLY recommended or erroneous system operation may occur.

This warning message can be safely ignored. The BIOS implements a superset workaround that includes the workaround required for Erratum 131.
