hallo, i am trying to install suse-linux on powermac 8500/180 - 64mg. macOS 8.1 i hav external 2gig HD :

3: SCSI, 1.91 GB, /dev/sdc, MICROP-4221-09 1128RQAV

This is what i attempt to choose for installation.

So you want to install Linux here. You'll need at least two partitions: - swap - root Three if you want to keep a bootable Mac OS partition on the same disk (but I suppose you have Mac OS on the internal drive, so you can/should copy BootX app, vmlinux and the BootX Extension there). The simplest way (I think) is: - boot from Mac OS - launch Drive Setup (or your favourite formatting utility if Drive Setup can't recognize the disk) and initialize the disk creating *two* (or three, see above) partitions: one 128MB (64 should be enough if you don't plan to add RAM to the computer) and another filling the rest of the disk. Both partitions should be set to "Unallocated". - now install Linux, and when it comes to the disk choice, use "custom... (for experts)" (well, I really don't think that this is for "experts"; Surely I am not... so don't be scared :-), then select and edit the two partitions (select partition in list then click Edit button) this way: 128MB -> format swap (mount point field will be filled automatically); <other bigger partition> -> format ext2, and put "/" (NO quotes!) in the mount point field. - remember to write down the root partition "name" (sdcX, where X should be a number between 4 and 8), because you'll have to put it in BootX. - continue installation BTW, you can find all this on the printed manual (although I must agree that it is not crystal clear...).
