I have now been able to successfully run 'dir cd:,\\' from the OF
prompt (very cool - remotely via telnet) - don't know why I was not
successful with this before my previous post, sorry for the noise.

With the CD inserted, burnt from the original "boot.iso":
1 > dir cd:,\\

     Size/        GMT                     File/Dir
     bytes   date     time   TYPE CRTR    Name
      2050 10/17/ 6 20:21: 7  tbxi chrp  ofboot.b
    145068 10/17/ 6 20:21: 7  ???? ????  yaboot

However, the TYPE and CRTR are not correct on the CD burnt from the
new "boot-new.iso":

1 > dir cd:,\\

     Size/        GMT                     File/Dir
     bytes   date     time   TYPE CRTR    Name
      2050 10/18/ 6  2:21: 7  TEXT unix  ofboot.b
    145068 10/18/ 6  2:21: 7  TEXT unix  yaboot

Here is my complete input/output for creating "boot-new.iso":

[root@fedora-ibook [__data__]]# test -d boot || mkdir boot
[root@fedora-ibook [__data__]]# mount -o loop boot.iso boot

Something still seems to be wrong/missing with the mkisofs options.
Maybe is has to do with the "no Apple/Unix files will be
decoded/mapped" warning? Please help. 

Thanks!
