"Partition map has no partition map entry!"

Hello,

Trying to install etch for powerpc (powerbook). After partitioning the drive (scheme shown below) the installer issued the following alert:

"Partition map has no partition map entry!"

I'm used to pc install and this alert is new to me. Any tips as to what's going on? I googled the message and didn't come up with anything helpful.

Thanks,

ab

Partition Table:

/boot 221 MB
/swap 2 GB
/ 2.5 GB
/home 4.5 GB
/usr 6 GB
/var 2.8 GB
/tmp 2 GB

http://www.debian.com/releases/stable/powerpc/ is the installation manual for PPC architectures. Have a look through it and see if you have missed any steps.

Thanks for the link. When the partitioner starts and displays the partition table, there was a 50 mg. or so apple partition. I removed that (or set it to be removed) and that's when the warning came up. When I leave it there, the system doesn't complain. Evidently some sort of partition/boot map resides in that lil' partition. Thoughts?

Thanks Again,

ab

Quote:

Apple Partition Map (APM) is a partition scheme used to define the low-level organization of data on disks formatted for use with Macintosh computers.

Apple disks are divided into blocks, with 512 bytes belonging to each block. The first block contains driver information. The actual partition map begins at block 1.

The Apple partition map is unusual in that it defines itself as one of the partitions on the disk. This means that every block on the disk (with the exception of the first block, block 0) belongs to a partition.

I am certainly not qualified to say so, but I fail to see how you need this to run Linux, if there is not going to be a Mac OS on this computer. I would run gparted (off its own liveCD or some other liveCD, they basically all have it) and delete all partitions on the drive, then install Debian. Don't forget the first sentence in this paragraph though (the error you get has me thinking there is something here I don't know to consider).
