Hi,

A while back I posted an great success overclocking an iBook 500@600Mhz/100Mhz bus, which has worked perfectly, up to now

Powered it down for a few hours, and restarted. I get the usual chine, the blank grey screen, then the grey Apple logo, which after about 2 seconds moves downwards about ten pixels ... and does nothing else. It allows me to use remote firewire mounting of the hard disk, however.

Tried my 10.3 Install 1 CD, which crashes to the error: "Unable to find driver for this platform: "Powerbook4,1"

Other things I've tried:
- Boot OS 9 - boots, but comes to 'bus error' halfway. Although, it always did that - think it needs 9.1, not 9.01 as I have
- Zapped PRAM/CUDA reset/got into open firmware and reset-nvram reset-all
- Held down shift, ctrl-c for "safe" OS X
- Removed 512MB RAM stick
- Tried another 2.5" hard disk
- Resoldered resistor moved for overclock (all others are conductive ink - I must redo this too)

Any other ideas?

... looks like I'll be underclocking it to see what happens. But just wondering if anyone else has had similar problems with their 1st generation iBooks.

I have seen this when I tried to re-install (curse you Fink) an eMac (which had 10.2) with the disks from my AlBook (10.3). Kernal panics on startup suck.

I had a set of purchased 10.3 disks I bought for the eMac as well, but could'nt find them. Eventually I booted the Emac in target disk mode, and installed the OS that way from the powerbook, which could boot from the disks.

Then I found the other disks. I booted the eMac from them just fine.

Just a thought...

onionhead, that was all it was - thanks.

Pulled the iBook apart twice, resoldered connections, before realising my 10.3 CD was flaky. A quick use of a replacement one allowed me to run Disk Utility, and repair the permission problem that prevented the hard disk from booting.

So ... moral of the story is, always check your boot CDs, and if your "grey apple" shifts down 10 pixels, it's a problem with the startup drive

Is there a way to check OS X installation CDs? e.g: with some sort of utility?
Or is it just "it installs, it's good"?

If it comes up with a kernel panic of "unable to find this driver X", it's likely your installation CD is corrupt. Thankfully I was able to borrow my brothers.

You shouldn't have clocked it in the first place. Your warranity is void now.

The warranty was void two years ago designers_hub Was a mid-2001 model. I wouldn't dare go near the internals of a Mac under warranty, especially if the parts are irreplacable. Now that it's out of warranty, I'm able to experiment a little and now it's more than capable as my main OS X machine, previously was a little lacklustre in performance.

Thank god. I thought it was another "My iBook has the logic board failure threads"
