My first guess would be the cable since you didn't get the error before changing it. Remember, when things start going wrong, always check the free/cheap solutions before spending …

hi!.. i just changed the ide cable of my g4 mac and now in the Disk Utility im get my drive in red { "lightbox_close": "Close", "lightbox_next": "Next", "lightbox_…

Do you hear the fan come on? If not, that's a problem... Are the vents unobstructed (internally and externally)? Is the G4 sitting on a hot plate? I have performed sustained, he…

So my PB is sluggish (has been for the last year) and everytime I play YouTube videos (much less DVD movies), the system overheats in like 5 minutes. Within 10 minutes of this over…

All but the ROM and the internal ethernet work just from a retail 8.6 CD.

One other thing that has occurred to me that is completely unrelated to the topic of the correct firmware required for booting into 8.6 is whether any additional 8.6 system files w…

I have done a lot of googling and have discovered the following: If you have upgraded the sawtooth firmware (aka boot rom) using the 4.x update, the ability to boot into 8.6 is di…

No luck for me yet, with ROM 2.5.1. My machine (ID 406) doesn't want to work with a September 1999 G4 boot CD. It also doesn't want to work with a retail OS 8.6 install with ROM 2.…

Ah, yes, this helps. I definitely have a 100 model because of the sticker under the battery holder. Who would have thought it would be so hard to tell apart? Anyway thanks. Pro…

Something I found googling around: http://normalkid.com/collector/100.html Hope it helps, Rick

My OMP has FCC I.D BCGH1000 Model Number H1000 and copyright of 1993 Mine was officially an Apple Service part and not retail, it came with NOS 1.11 I do not know about the 100…

I have an Apple Newton that I got for free. Judging by pictures, it must be either an OMP or a 100. How can I tell which one it really is? It's kind of a neat little thing and I…

Exactly. The G4 put a lot of power for a little money on the table. Traditionally that kind of CPU performance was only found with "The Big Boys". You know them as SGI, Sun and I…

I have read that the temperature sensor is actually part of the processor daughter card.

Yeah. Crazy feds. But at least we've got a chance for some improvement coming up in the next couple months. On topic, what other systems marketed at regular consumers ever had thi…

I own a Sawtooth but like almeath I don't have the original 8.6 install CD. Could someone who has the Mac OS ROM 2.5.1 file please make it available for download so that other Saw…

As far as I know the power manager (PM) circuit is built into the motherboard. It can be reset as above, and for reference here is the offical Apple guide on the subject: http://su…

When you say PM card, do you mean a replaceable card?

Try holding the reset button for 15-20 seconds, then let it go. If that fails, unplug the AC and remove any batteries, leave the system like that for an hour or so and then plug t…

Plugged a known working power adapter into the 1400c. Pushed the on key and nothing. Pushed the reset button at rear and the light at the top of the screen comes on. Nothing else …

Multiprocessing on the PowerPC 7xx-series chips was difficult because, like the 603 they were based on, they lacked the proper cache coherency protocols and the like to support pro…

I've wanted one of those ever since I first saw them reviewed in MacAddict magazine so many years ago. If I had the opportunity to pick one of them up, I'd do it in a flash if the …

I have seen that behavior ... I can't remember where. /wracking brain --David

The only fixable cause of that symptom is a display cable problem. The flex cable is not infrequently to blame. If squeezing somewhere on the edge of the lid around the display mak…
