Thanks for all the responses. [] ]'> The ROM on my B&W G3 CD is 1.4, and on the 'retail' CD it is 1.6. Unfortunately neither one will boot my G4. When running th…

I see there was a firmware update listed for the sawtooth G4s in 2001. It says it is for improved compatibility with OS X. I'll need to learn how to use Open Firmware to see if tha…

Hey Guys, Im looking for Lisa / Mac Portable Parts in Australia, I am currently participating in the Retro Challenge, but I'm now in a predicament! The Lisa 2 I have, which is an…

Ugh. A mobo swap in those is a long process. It is fortunately rather straight forward, and less blood drawing than an 8500. I wish you luck and much patience. TBird

A customer owns a Dual 1.8ghz PowerMac G5 that has issues. He also bought a stripped G5 containing a working mainboard. I get to take the non-functional mainboard from the origin…

Looks like liquid may have spilled onto the board at one time. I'd also replace that 5 pin IC next to that burned out IC, along with that capacitor between them. I small soldering …

Well, an update, though not one I'm happy about. I think I may have found the problem. I found a section of the logic board towards the very front, near the front latch, that loo…

It's possible it has a grounding problem because my iBook clamshell did not have the ground wire screwed into the metal shield and I could not get a charge or use the power adapter…

The iBook G4 may have been (relatively) free of the bad GPU issue, but it still had a fairly common issue: cracked solder joints, typically in the power section. There are some web…

I've got an iBook G4 (different iBook than the display plagued one) that has some sort of electrical gremlin going on. It's experiencing a few odd symptoms that have pointed to a …

I'd go with a firmware update. Its unlikely that OS X would have anything to do with it - despite the fact that I primarily run my iMac under Mac OS X, it will quite happily boot o…

You might be able to instal directly in Open Firmware.

Might be a firmware update, yeah.

Good news: I got a hold of ROM 2.5.1, on an installation CD for a G4 system. [] ]'> Bad news: The CD won't boot my G4! [xx(] ]'> According to the system profile…

I have a USB2 PCMCIA card that I can use if that particular change is made.

For my Lombard I just pulled 5v from the pads on the bottom of the mobo from the USB ports. They are nice and exposed and it is super easy. I have never used much more than a keybo…

I've heard of some people (like this one) using the +5v from the PCMCIA card cage to run the fan off of a little switch they've installed. May be worth trying, or googling for othe…

Can't say I know the inside of the Lombard too well so I might be well and truly off the mark here but is there any sort of thermal sensor that's tripping (or in this case not trip…

I replaced the fan and it was spinning OK when installed. Heck even the original one looked OK.

Can you spin the fan with your hand? Check the connections.

Is there any sort of utility to turn on the internal fan on a Lombard? This thing is overheating and locking up. The cooling fan is not turning on at all. I'm working on a new s…

Actually, I got the keyboard working! (The contacts were a little dirty) Thanks for your help!

Everyone I have asked says that they either don't have the original install CD or that it came with OS 9. All the copies of 8.6 floating around the net are March 1999 retail copie…
