I recently acquired a 350MHz blue & white G3, my very first non-x86 machine. I have done a lot of x86 gentoo installs, but this is the first time I have ever tried to do anything on a Mac.

I'm following the PPC handbook, and unfortunately, I've hit a snag right at the beginning.

In mac-fdisk, I can't seem to delete partitions.

Code:

Command (? for help): p
/dev/hda
        #                    type name                length   base    ( size )  system
/dev/hda1     Apple_partition_map Apple                    2 @ 1       (  1.0k)  Partition map
/dev/hda2               Apple_HFS Gentoo Linux 2005.1 ppc  810384 @ 16      (395.7M)  HFS

Block size=512, Number of Blocks=810400
DeviceType=0x1, DeviceId=0x1

Command (? for help): d
The map is not writeable.
Partition number:


I've never seen an error like this using the plain old fdisk, so I have no idea what to do here. Any help would be greatly appreciated.

Maybe it doesn't want you to overwrite the Apple partition map? Try deleting hda2 and creating on or two mammoth partitions (root and swap) while leaving the partition map.

I'm pretty sure you're supposed to leave those...

I have a perfectly working gentoo on my powerbook now and those partitions stil exist, I never had to touch them.

Fair enough. I'll try just adding the rest of the partitions as listed in the PPC handbook to the existing partition table and see what happens.

It sure feels wierd to have that "I'm totally new to this" feeling again after years of working with x86 and linux...

I'm still having problems with mac-fdisk

I'm trying to create an Apple_Bootstrap partition like the PPC handbook says, but it still seems unwilling to work

Code:
Command (? for help): b
The map is not writeable.
First block: 3p
Bad partition number
Command (? for help): b       
The map is not writeable.
First block: 2p
requested base and length is not within an existing free partition
Command (? for help):


I really have no idea what is going on here. Please help, I'd really like to get this machine working.

Well, I finally figured out the problem, and boy is it a special one.

Seems like this particular G3 likes to detect the CD-ROM drive as /dev/hda and the HDD as /dev/hdc

So I was trying to write stuff to a CD using a plain old CD-ROM drive...which was never in a million years going to be able to help.

Thanks to all for looking and offering advice.

How exactly did you get it to work. I somehow deleted the Apple partitions and I have all sorts of errors trying to install Gentoo or Mandrake or FC4. If its not a kernel panic error, its giving me errors because I think its trying to write to the cd. How do I fix this?
