[syslinux] Failure to boot isohybrid image from USB stick

The first one says "Award A7V8-X ACPI BIOS
Revision 1008 12/29/2003".

The second one (started by the first when
finding the IDE controller, i assume) says:
"Ultra133TX2 2.20.0.15  1999-2001 Promise Inc."

The latter offers me a menu of boot devices
if i press some keys (probably Del or Space
does the trick). This menu offers "USB ZIP"
if the USB stick is plugged in. After selecting
that item once, the system reacted on the
USB stick at boot time. Previous to that it
ignored the stick.
But it boots RIP 7.0 only if it was repacked
by RIP's mkusb.sh. 

I am currently trying to find out how
the parasite BIOS gets started and whether
i can disable this without touching the
shaky hardware. They call it "BIOS" not
"bootloader".

Any hints are welcome.

At least with the BIOS in question it seems
to be about isohybrid, not about hardware
detection. (Although unpacking RIP's archive
lasts about 10 minutes which is absolutely
not normal. USB hardware is 2.0. Shrug.)


Have a nice day :)
