General Hardware Discussions / Re: What impact would a bad IDE cable have?
« Last post by GaryN on Today at 02:29:08 PM »
Without knowing which accelerator we're talking about, it's difficult or impossible to offer any better advice.
I will note that most, if not all 3rd-party CPU's require an extension to be loaded in ≤OS 9 that is not required in OSX.
That could explain the boot-from-optical issues if that System does not contain the Extension.
The next question is of course, why are you booting from disc? When you install an OS on the HDD, you then get to adjust and modify it to run it's best on your machine… but you already know that.

More info will produce better results.

I submit that THIS is by far the most likely culprit for symptoms of "freezes & intermittent boot failures".
I understand (and sympathize) that you would really rather it be a simple bad cable, but realistically…

When I bought this machine, I realized it might have any number of possible hardware issues. Given I bought it with the accelerator installed, I don't really have a previous state to compare it to. The previous owner - who primarily ran OSX on it - said it was very stable for them. It also seems quite stable under OSX, with no random freezes that I've experienced, and I've left it up and running for days. I only get random freezes when it is booted into OS9. Boot failures have - more often than not - occurred when I was trying to boot from optical media.

As an alternative to problematic machines like G5s and OS X only video drivers, has anyone looked in to hacking the OS X Classic Environment to be more full featured?

I know in Rhapsody, the Blue Box environment booted up full screen and had full Finder. I wonder if there's a way to recreate that behavior in later OS X releases? If so, in theory we could have a small OS X environment boot up on the machine and then auto launch in to full screen classic.

I'm not even sure where to start with exploring this, but wanted to share in case anyone has tried something similar.

All I can remember is that Apple removed booting from PCMCIA/Cardbus starting with the Lombard, so OF might be missing a driver for the Cardbus hardware. The Lombard is the first New World notebook, so OF got an upgrade from what went before and the boot process changed from using  OF/Toolbox to just OF.

That does indeed highly suggest that OF never had a cardbus driver.

Can we take a look at the OF device tree for the laptop?

Mac CPU Upgrades / Re: QS 733 to 867

yes, you can swap those processor cards. i think you could also use the 2002 ones, it is the same connector and bus speed.

for certain applications it makes a huge difference.

wait a moment until someone might have to correct me before you plug it in.

i DO have a 733 with a 867 card from my recent leftover-components-assembly, but i cant remember if i already booted it.

I've been trying to track down what's causing the random system freezes & intermittent boot failures on my accelerated G4 DA,

There was an old story, sometimes told in cartoon form where Joe sees Ed across the street looking around under a streetlight.
He yells, "Whacha doin', Ed?" Ed says, "Looking for my wallet. I dropped it over there"
Joe says, "If you dropped it over here, why are you looking over there?"
Ed says, "The light's better over here."

Mr. Sax,

Perhaps you somehow did not see or did not read my reply to your previous inquiry re: Galaxy.
