This archive includes a self-extracting diskette image of the bootable BIOS 
update diskette.  The image file is named BIOSDISK.EXE.  To create the BIOS
update diskette, type the following command at the command prompt:

 BIOSDISK A:

This requires a formatted 1.44MB 3.5" diskette, and assumes that the 3.5" 
diskette drive is on A:.  If your 3.5" diskette drive is other than A:, 
substitute the desired drive letter in place of "A" above.
