Re: x86'er needs help with an rs/6000
To anyone who might be reading this thread: I really need some help
getting this RS/6000 F40 (7025) to boot linux, see my last couple

Thanks for the info, I'll keep Kingston in mind but for a while 256MB
should be fine (if I can get this machine running, it'll be a web server -
eventually with a database running on it...). I probably can get those 16
port boxes (the suit who sent me the machine has no idea which dusty parts
sitting in his closet for 2 years goes with the RS/6000) - but until I
know the controller can work with linux, I don't want to bother - already
spent $166 US on what I've got so far...

I forgot to mention that I don't have any access to the installed AIX - no
root password, no user accounts - luckily SMS didn't have a password set.
I'd really like to play with AIX (maybe even keep it), but I don't have
the money to buy the OS. I could configure a PC to have the same network
route as AIX (changing the IP addresses in SMS probably doesn't affect
AIX, right?), but I don't have the time nor experience to hack the box
over ethernet (if it's even possible).
Linux is the goal - Debian of course. Thats where I'm stuck right now.
I've looked at the so called "redbook" from IBM, and it says this machine
is PReP and not CHRP (unlike the model F50) - but I can't verify that with
'bootlist -T' (no login). I havn't been able to find/use any firmware
boot commands, but I can change the boot sequence to floppy first (and
only). So far I've tried PReP floppies from www.debian.org/~porter/prepdl
and sid/main/disks-powerpc/current, as well as CHRP floppies (though I
guess the floppy doesn't work for that arch anyway) - they all just hang
with no indication of whats happened (the logo screen sometimes scrolls up
a few lines as though some text has been printed, but it must be white on
white!). I've even been able to verify the floppies from the AIXish
"Service Mode" -> "Service Aids". I'm going to give TFTP/NFS a try in the
next couple days - but disks-powerpc/current doesn't seem to have any TFTP
boot images :-(
I realize getting this hardware to run linux may be well over my head, and
if it turns out that only a kernel hacker or debian guru can make it work
perhaps I can persuade the owner (I havn't been given ownership until I
can make it useful) to donate (tax write-off?) the machine to Debian
(perhaps a kernel hacker would be more appropriate though). What do you
Any help here would be much appreciated.
