KB-6120 BIOS Update Page

Before updating BIOS, note the following:

  • it is NOT recommended to update BIOS just for the sake of "having the latest BIOS available"
  • in 95% of cases, the latest BIOS does NOT "increase performance"
  • before updating BIOS, get familiar with BIOS Update Procedure and make sure you backup the old BIOS to a floppy
