The list shows the BIOS version starting with which the CPU is supported.
All the newer BIOS versions starting with the listed one will support that CPU.
As an example, for the 990FX R2.0, the FX 8320 is supported starting with the 1006 BIOS version. All the newer versions, 1101 and 1201 will also support the 8320.
Depending on the manufactured date (before or after the BIOS version released date), the board might or might not have the required BIOS version, therefore the update need.
now i get it. thank you so much for the info. i appreciate it a lot.
