Peter,

Will you be changing your future isolinux releases so that it
works on my hardware?

i.e. if when scanning drives numbers you find one that returns a
spec packet which doesn't have the sp_drive field set, accept the
drive number if it matches the drive initially passed in dl OR 80h.

p.s. I see from http://git.kernel.org/?p=boot/syslinux/syslinux.git;a=shortlog
that you've done the 13 to 13h change.
