Thank you Tsubai,

Adding '-hfs -part' did the trick to make my cd bootable -- at least some of the way.

On my Powerbook G3 Bronze (Lombard) this allows me to boot a kernel off the CD (this
is the 400 MHz, so the drive is actually a DVD drive). It proceeds to probe devices,
but turns the light on the screen down to grey-on-nearly-the-same-shade-of-gray, but
it is just possible to follow the boot process. It does not recoginize its boot device
(the HFS part of the CD) and asks for root and swap partitions, then for file system
type. Then it just stops -- no messages, no nothing... Any explanation ?

A second question: How does I boot from the CD on my Beige G3, DT 233MHz?
It has no cd devalias:

Open Firmware, 2.0f1
To continue booting the MacOS type:
BYE<return>
To continue booting from the default boot device type:
BOOT<return>
For Open Firmware serial I/O type:
TTYA IO<return>
 ok

Any good ideas for this one ?
