Thank you.

My BIOS does not have options for USB-FDD/ZIP/HDD/CD, as the type is 
detected at boot time.  UFD's appear as "USB Flash Device" and boot in 
USB-HDD mode.  If I burn one of these ISO's to a CD and boot it, some have 
an "Install to USB" option which installs SYSLINUX as the bootloader, and 
that does create a bootable UFD for me.  I'd just like to skip those steps 
if I can...

I will try running the isohybrid script (with parameter tweaks) on the ISO's 
myself and see if that helps.
