SMP on 9600 Success; First Time Poster
Hey everyone, Recently I bought an old 9600 200MP for $150 from a local Goodwill store. Since I've been a machead for a long time, and have recently been getting involved in *nix (Solaris and Linux) I decided I'd put Linux on it (I was originally looking for a Sun box, but saw this and couldn't pass up the opportunity). So I read up on the different distros, and decided to try MkLinux. I realized later that MkLinux is a dinosaur and almost no development is still done on it (not to mention SMP ain't easy to enable), so I went with Debian instead (on a friend's recommendation). I added some memory to the system so I now have a total of 608MB, all interleaved. I also added an adaptec 2940, a 4GB 10,000 rpm cheetah as the swap drive, a 3com 10/100 NIC, a Promise Ultra66 IDE controller, and an ixMicro TV tuner card. I had some trouble getting SMP working, but I finally figured out the precompiled Debian 2.4.18 SMP kernel was flipping my SCSI buses (Ben H suggested this to me), so after resetting those in quik and in fstab all appears well. I've attached the ouput from "cat /proc/cpuinfo" to the bottom of the message. I'm now running distributed.net, with 200% CPU usage! I also had some video problems with the IM Twin Turbo drivers, so I just passed "video=ofonly" as a kernel argument disabling hardware acceleration (not important to me, this box is going to be run headless once I get it set up - I didn't even install X windows). I just wanted to say I'm glad to see that Debian is the Linux of choice on PPC today (YDL too) and that there is a healthy PPC linux community. I hope to be active on this list from now on, with conflicts and problems if I find them. If anyone else needs help on an SMP system, I'd be glad to share what I've learned, albeit I'm still a newbie at this, too.

Re: SMP on 9600 Success
Hey, Just letting everyone know I wrote up a detailed report of my experiences on my website (go to http://drbobguy.freeshell.org and click on "steidh"). I know its written from a newbie perspective, but I thought it might be of help to people in the future trying to get SMP working (I couldn't find much documentation on this and I know something like this could have helped me).

Re: tiBook CPU speed
Go to the main penguinppc.org page. Apparent BenH has gotten the 800Mhz TiBook's to run at native speed. I have a hunch though, that maybe the 667Mhz and 800Mhz TiBook's are exactly the same hardware, and it is only a software hack to get them to go to 800Mhz (this is why the speed throttling on the 800Mhz only goes down to 667Mhz). Wouldn't it be interesting if there was a hack so that all of a sudden the 667Mhz is equal to the 800? Since the rest of the machine is exactly the same except for addon components like RAM and Airport, it certainly would entice many people to get a low-end TiBook. Who knows, hopefully BenH will say something about it.

I imagine that if it's a state, I can just go and reset it in Open Firmware, and everything will be OK, but for laptop users, being able to throttle the CPU speed is really useful. A cursory poke around the PPC 7455 docs on the motorola website seems to indicate that the speed throttling isn't done with an MSR on the CPU. I don't know where to look for good documentation about Open Firmware and Apple hardware (any pointers?). Toby. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
