Q: Why can't I use the AMD Barton 2500+ CPU on the KV7 after flashing the BIOS to v1.2?
A:

<Symptoms>
There are some symptoms after flashing BIOS to v1.2 with Barton 2500+ CPU
installed on a KV7 board.

  1. The system can't be booted up with Barton 2500+ after flashing the BIOS to v1.2.
  2. The system can't be booted up with Barton 2500+ after saving the correct CPU frequency setting in SoftMenu.
  3. The system can't be booted up by certain AMD Barton / Thoroughbred CPUs with correct frequency settings.

<Solution>
At present, there are two ways to solve the issue:

  1. Downgrade the BIOS to v1.1.
  2. Set the CROM1 jumper from 1-2 to 2-3.
  3. The issue will be fixed in the next BIOS release.
