Another option, and something that I use to build "Swiss army knife"-type utility USB drives is Easy2Boot. Http://www.easy2boot.com It builds the bootable environment, you just add the raw ISO or what have you, in the appropriate directory and away you go. I do SL installs with it since I can load my system diagnostics on the stick, run them, reboot and drop into the installer without changing media. --- A Sent from my Windows Phone ________________________________ From: Lamar Owen<mailto:[log in to unmask]> Sent: 8/22/2014 8:59 AM To: Scientific Linux Users<mailto:[log in to unmask]> Subject: Re: How do I create a Live USB with DOS 6.22?

(The ms-sys package can be found in repoforge; specifically, see http://pkgs.repoforge.org/ms-sys/ ). Alternatively, use unetbootin (available for SL in the EPEL repository) to make a FreeDOS USB stick; for most BIOS flashing and similar purposes a FreeDOS USB stick works fine.
