[CentOS] mkisofs help?

Hi All,

I am following: http://www.linuxinsight.com/how-to-flash-motherboard-bios-from-linux-no-dos-windows-no-floppy-drive.html

to make a bootable CD to flash my bios

I get to mkisofs step, but what I get is not what I think I want.

I dont understand if I unmount /tmp/floppy how the Mkisofs command of: mkisofs -o bootcd.iso -b FDOEM.144 FDOEM.144 how I get everything in /tmp/floppy

Here is what I did:

wget http://www.fdos.org/bootdisks/autogen/FDOEM.144.gz

gunzip FDOEM.144.gz

mkdir /tmp/floppy

mount -t vfat -o loop FDOEM.144 /tmp/floppy

Copied the flash files to /tmp/floppy

umount /tmp/floppy

mkisofs -o bootcd.iso -b FDOEM.144 FDOEM.144

Can anyone help?
