I need to do a firmware update on a Dell FS 7500 and it requires a bootable USB drive. You then copy the file over to the bootable environment, plug it in to the FS 7500 and boot from the USB drive. Then run the firmware update. I tried making one with the MS tool and it want's to install windows, which was great information to know, but not what I was needing. Does anyone out there know of a USB boot environment that I can boot into and allow me to run this firmware update?
