the is instructions in the zip that you download from MSI.
The just of it is as follows.
unzip to a location on your hard drive eg: c:\temp
using a bootable floppy boot your computer and CD to the directory that contains your bios update.
launch the utility by typing is name. follow the onscreen instruction to a T.
I will assume that you have writen down all information from your bios. After flashing my MSI board to 1.4 it reset all personalized items to defaults. Like memory config and boot devices... be sure to record all info. However I used MSI Live to flash the bios.
this is a quote from the MSI how to file
DON'T FLASH FROM A FLOPPY DISK!!!!
DON'T FLASH WHEN YOUR SYSTEM IS RUNNING FINE!!!!
DON'T FLASH IF YOU DON'T KNOW WHAT YOU ARE DOING!!!!"
