Flash your motherboard BIOS to the updated version

MotherBoard BIOS get updated from time to time from vendor for the fixed.  Some unusual and performance issues happening to your OS may be BIOS's bug.  It is always encourage to update your BIOS to the latest available version.

Performing BIOS update need extra care.  Here are some rules to follow:

  1. During the flashing period, your PC must always stay on with power.  Any power failure in between may make your PC totally un-bootable
  2. Always check current BIOS version with the latest version to make sure you download and updated with correct one.

In old day, the BIOS update file size always fit to a 1.44MB floppy disk.  We just create a floppy image from the BIOS flash disk image and boot from the floppy disk will complete the update task easily.  However, PC do not equipped with 1.44MB floppy drive nowadays.

BIOS flash file size is getting bigger now can't fit into a 1.44MB floppy disk.  Vendor may recommend user create a bootable USB flash drive and copy the files into it and boot your PC from bootable USB flash drive.  Other vendors may have a utility to install a software into your Windows Operating System to perform update.

For me, I like the bare bone method that just run a simple flash .EXE utility on DOS.  However booting from DOS is not easy now.  One easy option is:

  1. Create a PXE environment in your network
  2. Setup a DOS image that support network in PXE boot option.
  3. Copy flash utilities and BIOS file in network share folder
  4. Boot your PC from PXE environment and select the DOS image
  5. Run the flash utility

This purely network BIOS updating solution should works usually.
