A lot of older machines have problem with USB booting in general, and
with isohybrid in general.  On some machines you can make it work by
either tweaking the parameters to isohybrid (especially -s 63 -h 255 on
some systems, -offset 1 on others, and -entry 4 on even some others), or
by changing the settings in the BIOS; in particular, you may need to
change between "USB-HDD" and "USB-ZIP".
