1) Boot Mac OS X Tiger from a different disk, then use pdisk to partition your internal disk. 2) Hold down "T" while booting your iMac, then connect it to a different Mac that has Firewire and use pdisk from Mac OS X on that Mac to change the internal disk on your iMac. 3) From Mac OS 9, run NetBSD's pdisk. I had to use the mac68k version so it would see internal ATA disks (the ppc version only sees SCSI disks); pdisk is available here: https://cdn.netbsd.org/pub/NetBSD/NetBSD-10.0/mac68k/installation/misc/pdisk.sea.hqx In Mac OS 9, pdisk (somewhat unsafely) lets you change (or rename) partitions even if they're active. That can come in handy if you can't boot from a different disk. hope that helps -Stan
