Crap. I really didn't want to hear that. I've got 2 Powerstation 220's
I picked up cheap and put memory and disks in hoping to be able to run
Linux on. Unfortunately, PowerPC Linux only really supports machines
with PCI bus's, and the 220's have IBM's Microchannel. Which they've
apparently tight-lipped about with the specs.
I got a copy of 4.3 AIX with the hope of at _least_ getting these things
up and running, but the disks have _no_ OS, and the machines only seem
to want to boot from the network device (in any mode). An AIX friend
(I'm a newbie) said to try:
bootlist -m prevboot
bootlist -m service cd0 hdisk0
but that method requires having an OS installed in the first place. I'm
really astonished to find out that a machine made in the '90s would
require a TAPE drive to install the OS (from scratch).
Howver, I do have access to an IBM 8mm tape drive, but I doubt I have
tapes (or access to get them). Would it be possible to dump (say with
dd) the cd's to 8mm?
My machines do have floppy drives. Is there any hope with that route?
Are there any particular models I could clone a disk from and be
safe? My friend has quite a few RS/6000, but I don't know the models...
