Report on XPostFacto 4.0/CPU Director 2.1 problem (and workaround)
Friday's news mentioned the XPostfacto 4.0 update. A reader sent a note on a problem and workaround he's seen with it and PL's CPU Director 2.1:

" Hey Mike, don't know if others might notice this but I seem to have found a problem with Powerlogix's CPU Director software and installing X.4 via XPostFacto on my Beige G3. If others ask, this is a slight work around that I found:

At least on my setup anyways, CPU Director will not function on startup on my Beige (PL800Z, can OC to 933Mhz) with OS X 10.4 or 10.4.2. Now this isn't older pre 2.0 CPUD versions. This is CPUD 2.1, the latest version. Which should work, right? Well, not exactly.

So anyway, everyone knows PL added DFS (dynamic frequency switching, See PL press release on CPU Director 2.1-Mike) support to CPUD. This enables the energy saver functions for the 750FX/GX and 7447s upgrades in the energy saver panel. A virtually useless function for me since I own a tower. (?-Mike) But on boot up with 2.1, it gave me the kext files was disabled message and after I reinstalled the PL kext files with 2.1. I noticed clock speed was 467Mhz on highest. Trying to clock back up to 933Mhz would result in a complete crash as well. So figuring CPUD's failure to load on startup was some problem with XPF's X.4 install, I decided to focus my attention on finding a way to turn off DFS so I could at least clock my CPU. Thankfully when X.4 was first booting for some reason it was in verbose mode (I didn't set it in XPF, it just did that after reboot). This told me the names and locations of the PL kext files, the ones that looked to be controlling DFS on startup. So I hunted them down, all 4 files have the name PLCore/etc and are easy to find. Once removed in OS9 (might be able to do this in safe mode OSX). I proceeded to test out OSX again. Sadly CPUD still will not load on startup, but I had successfully disabled DFS. However, when attempting to load the main PL kext file in OSX all it would show me is the accurate Mhz of what my CPU was running. It would not let me clock the CPU.

Which now leads into the next part of this work around. When I downloaded CPUD 2.1 I also got 2.0b1, just incase anything went wrong of course. After finishing some updated I finally decided to take a look at 2.0, which does not include any DFS files. So I figured to give it a shot to see what happened and, well it worked. I can now clock my FX back up to 933Mhz. Startup is still dead but at least the CPU will clock again.

Now on Powerlogix's website it states 2.0b1 will not function in X.4.2. I remember running 2.0 on other systems and seeing the message that I needed to update for X.4.2. So it seems to get this all to work you would need the 2.1 main PL kext file installed first before running 2.0. After that, it works just like normal, minus the disabled at startup messages. So all PLL control has to be done manually after startup unless you have your CPU already set for your desired speed via it's onboard controls. But those of us that sometimes need to boot OS9 know these upgrades do not do well with OS9 at high speeds (well known problem with firewire drivers/ATI drivers). Which is why mine is set to 733 so it doesn't go nuts in OS9 as quickly. Otherwise I would have my CPU set for 933 via the onboard switches.

Hope this might help someone if you happen to get a question about this. Hopefully XPF will see an update that might address this problem, or CPUD will be patched again soon. Whatever comes first, who knows.

Report on Audio Noise in Tiger during Graphic/Video Tasks
" I wonder if I can ask you or the readers of Accelerate Your Mac if any else has experienced the problem which I have just noticed.

My G4 Digital Audio makes a noise thru the speakers when I scroll windows using my wheel mouse or if I scroll through menus or if I just drag a window around the desktop, if I stop all motion the noise goes away but I can still hear a tiny amount on static/white noise, if I begin movement again I can hear the RFI (that's what it sounds like), I first noticed the noise about a week ago after I'd been playing some mp3's on iTunes and left the volume up high by accident. Now the noise is bugging me as I don't recall hearing the noise before.

I can hear the noise as well if i use an Griffin iMac as the audio out with a pair of Sony Fontopia phones

Thinking it was something that I added to the G4 I took out all the PCI cards and just left the CPU upgrade in and the SATA card and AGP card but it still did it.

Having conducted some more tests from what I can tell it something related to Tiger 10.4.X & My Digital Audio G4, I have a firewire drive with Panther 10.3.7 on it when I boot off that I can't hear the noise at all.

Thinking it was something wrong with my Tiger install I cloned my iBook G4 1.33 (10.4.2) onto the G4 in target disk mode and it still makes the noise. The iBook G4 is noiseless.

G4 Digital Audio w/Giga Designs Dual G4/1.2GHz over clocked to 1.4GHz, 768MB ram, 320GB SATA Raid 0 (2 x 160gb Maxtor DM+9), Firmtek 1S2 SATA Card, ATI Radeon 9800Pro, Alchemy DVR, GeeThree Sweet MultiPort
I'm not sure but I don't think the noise was there under 10.4.1 or .2
I'd welcome any thoughts opinions on this as I have no idea what's wrong
Thanks, Mick B.
(I asked if disabling the Sound Prefs setting for "Play user inferface sounds" changed the behavior-Mike)
I tried to disable "play user interface sound effects" but it did not make any difference.
I've also done an OF nv-ram reset as well and set-defaults
I logged in as root and removed all the audio kexts and then booted again and sure enough I had no audio at all, but I did have silence. I then put all the Panther audio kexts in the Extensions folder of Tiger and booted but still had the same audio problem.
I'm at a bit of a loss with this one. "

Almost makes me think it's PS related, but he said it doesn't happen in 10.3.x.
(Update - I had about a dozen readers reply to this and posted a separate page of them.)

If you've added a IDE, SCSI, Firewire or USB hard drive, CDRW, tape drive, etc. make sure you add a report to the database. (If you post an updated entry - make sure you use the same name, etc. as you did before so I can find your past entry. Thanks.)
(Incomplete entries are deleted. Do not post questions in the database, it's for drive reports not questions on what drive to buy - for that try searching the database for reports from owners of your mac model on the drive type/brand/interface, etc. you're interested in.)
