Just on this topic there was an interesting article today on my favourite mac news feed:

http://www.newsnow.co.uk/newsfeed/?name=Apple+Macintosh

It talks of the merits of the G5 over the intel macs for this sort of problem. Worth a read.

Intel v. PowerPC: Was the Old Way Better?

It does take a lot to kill a PowerPC Mac to the point that it won't boot. There's enough info in hardware ROM (about 1MB's worth) to boot the thing. The rest is in software. Mac users went for decades blissfully unaware of PCs' BIOS hell. You could always boot the Mac in FireWire (or SCSI) target disc mode.

Intel's EFI is better than BIOS, but it still can't compete with PowerPC Macs' hardware ROM.

Okay guys - I'm uncertain of what I should do next.

Both Master and Slave Drives show a happy colourful GUI, and both will boot from a Mac OS X 10.4 Installer Disc... however - when both were brought back from the dead, both displayed a really crummy GUI - see here by what I mean about crummy:



and this is the same GUI I was presented with, on the Slave drive when the whole PMG5 began to screw up... but it's not happening anymore... so I'm not certain what to do.

Do I... reinstall EVERYTHING from scratch, which will take a few days, only to find it slowly screws up again... or do I... "what"?

TTPro and Disk Warrior showed no errors, (even when nothing worked) and S.M.A.R.T. Status passed on both. ¿

What about try on the Apple forums.

I had some success with some of my Apple programs that didn't work.

Queries can be answered by Apple techs.

They really guided me through well.

I'm betting you have screwed hardware somewhere.

What I'll do Curra - is slowly build everything up again - it was a graphics work station - so I'll install Adobe CS 2 and Scanner / Printer Drivers etc - as there were little fuck-ups in the past, before I started this no boot thread.

Here were the anomalies via software:

  • 3D Perspective Effect in Photoshop never exactly rendered what it showed in its preview.
  • Tilt Tool in Illustrator never tilted objects the way I'd set them after I let go of the mouse.
  • Extensis Suitcase X1 never remained hidden on start-up, even though it was ticked in Account items to be hidden on Start-up.
  • Extensis Suitcase X1 claimed certain fonts had no Post Script Out-Line, even though they worked fine on my other Macs.
  • iPhoto always demanded I rebuild my Library on the basis it was too full, yet there were only 800 images there.
  • SilverFast Scanning Software always showed the outlines of former cropped images, and there was no way to delete them.


If I see these things beginning to happen again... I'll know something is horribly amiss with either the drives or the logic board.
