15 inch, Tita. model

The cpu will only run at 667mhz ( 66 % )

At YDL's website, they said to type this :

cat /proc/sys/cpu/0/speed-max > /proc/sys/cpu/0/speed

but when I do, my powerbook turns off

I have 3 different files in /proc/sys/cpu/0/ : speed-max ( 1000000 ), speed-min ( 1000000 ), and speed ( 667,000 )

HELP


Also, programs are slow to load and it feels kinda sluggish. Is DMA enabled by default ?

Well, my knee jerk reaction is that this is a kernel bug, what kernel version are you using?

You can get updated kernels from www.ppckernel.com, but I have no experiance with Linux on PowerPC so I can realy help you much out in that department. If your lucky then they have this fix already. I'd use a "stock" kernel if at all possible, don't use any "-pre7" or anything like that, unless you feel adventurous.

They also have forums at ppckernel so that maybe they can get you help. There is a big powerpc user base at gentoo.com so you can try the forums there.

....
if
cat /proc/sys/cpu/0/speed-max
results in
1000000
then maybe try a slower speed of
900000

Like
echo 900000 > /proc/sys/cpu/0/speed

Just a guess.


The utility for controlling IDE drives (NO SCSI) is hdparm.

hdparm /dev/hda

will give you the current settings of your drive, and

hdparm -i /dev/hda

will give you the firmware specs on your drive. (as long as /dev/hda is the same in powerpc linux as in x86)

man hdparm

for howto set the different settings. BE CAREFULL, some are dangerous and will crash/hurt your HD.

Unfortunatlly I realy have NO powerPC linux experiance, I want a ibook, but it's going to be a couple months at least before I get one. :(

I'd try something other than yellow dog. It doesn't have quite the number of people behind it as the bigger distros, and I don't know of any big reason to use it over something else.

Thanks Drag

I have 3.0 installed, downloaded from linuxiso.org and I just noticed on YDL's mirrors 3.0.1 is downloadable... *sigh* ( I hate 56k )


3.0 = 2.4.20 kernel
3.0.1 = 2.4.22 kernel

I will try 3.0.1 and if I can't get it to work I will download a PPC Mandrake
