Its a lot more comfortable to update the BIOS by using generated ISO image with all needed files to update, then to struggle with old floppies, which you also not always can use, below is a script that generates bootable ISO image called
cd.iso, you can burn it and use it to update you BIOS.
I also attached bootable floppy image
__bootable.img that is needed to create such bootable ISO, which you need to
gunzip and put in the same place as the script.
Code:
#! /bin/sh
BOOT=__bootdisk.img
if [ ${#} -eq 0 ]
then
echo "usage: $( basename ${0} ) BIOS.rom FLASH.exe ..."
exit 1
fi
mkisofs -J -R -b ${BOOT} -o cd.iso ${BOOT} $@
