But the computer ignored the USB stick before
i negociated with the Promise BIOS while the
USB stick was in.

either by booting from FAT or by stalling on ISO+MBR.
So the Promise BIOS is in some way involved.
I know that an identical Promise controller reliably
prevented booting from a SATA disk in another computer.
It appears not so much as extension but as occupant.
My reason for having it was to operate three DVD
drives and a hard disk simultaneously without clogging.
Meanwhile that computer serves as retirement home for
half blind IDE burners.

I'll try to get some.
I consider to pull the Promise controller
for a test. There will be no hard disk and
possibly i won't be able to close the box
afterwards.
(It looks like the plumbing in the movie
"Brazil". My ninja plumber will only be
available in about one or two weeks.)

Will it suffice to replace /boot/isolinux/isolinux.bin
in the RIP-7.0 image or will i have to learn how
to build own bootable systems ?

Well understood. I'm crossing fingers for you.
It is not overly urgent for me.
I mainly wanted to test xorriso's isohybrid feature.
Well, at least it is not worse than with your perl
script. {:)
The only thing about which i am impatient is to
hear that it is *as good* as your script's output.
I will stick to the issue and report about
any new insight.
Have a nice day :)
