What does it do instead of bonging?

Try reseating the memory.  Try running on only one stick of known-good memory.

Any kernel panics?

If you can get it to boot at all, peruse the system.log for error messages.

Rosetta supports Carbon applications.  This is an API that supports

Good catch, thanks!

Rosetta does not support the pre-Carbon environments.  And the later 
vers of Rosetta apparently supported some G4 and Altivec instructions 
(but not the G5 specific ones).

Not exactly true.

Intel System. Some of the software is "universal" (meaning contains

The ppc-to-x86 code translator, Rosetta, is installed by default in 
x86 Tiger, giving it the ability to run ppc-only (non Universal) apps.


Rosetta requires apps that use use at least a G3 processor & Cocoa.

Rosetta does NOT support:
* Applications built for Mac OS 8 or 9 (that was Classic's job).
* Code written specifically for AltiVec
* Code that inserts preferences in the System Preferences pane

* Kernel extensions
* Bundled Java applications or Java applications with JNI libraries.


Leopard 10.5


Same Rosetta.


32-bit only.


No.  The x86 Leopard build includes both a 32-bit and a 64-bit 
kernel.  It can only boot into the 64-bit kernel, however, if the 
hardware supports it (Core 2 or better) and all the kernel extensions 
are 64-bit.


Above the kernel, both 64-bit and 32-bit frameworks and apps can run. 
"mixed mode".



Snow Leopard 10.6


Snow Leopard contains many more 64-bit components, but is not yet 64-bit pure.

Rosetta is now an optional install.


Lion 10.7 - Intel-only 64-bit-only architecture.


The kernel and all Apple-supplied kernel extensions are 64-bit.

Frameworks and apps can run in either 32-bit or 64-bit mode.

Rosetta won't run, so no more ppc apps.  Beyond Jobs' deep seated 
desire to fark those of us who are no longer good Revenue Units to 
Apple, this does make some sense -- Lion is 64-bit and G3 is 32-bit.

Re: More on adding an HD

So, if I get it correctly...
the Mac boots/runs fine from this HD?

> I plugged in the WD HD and the computer does nothing.
... But it can't recognize the WD HD?

It could be a problem of Master/Slave assignment.
On each ATA/IDE bus (the bus where the HD and optical drives are connected),
you can have one Master (or only) drive, and - optionally - a Slave drive.
If you have two Masters or two Slaves, the computer gets confused and the
HDs work bad (or don't work at all).

To select which is which, you use tiny jumpers connecting pins (the pins are
usually eight, arranged in two rows).

> The iMac HD has a pin connecting the last two pins
> vertically. Should the drive I am trying to run as a slave be pinned also?
The pin configuration is not the same for every HD: each brand can use a
different scheme.
Usually there's an explanatory drawing on the disk label, showing the
possible setups. Sometime this drawing is missing, though.
If you can't find the drawing, you can Google the drive model and "master
slave": you'll probably find some page with instructions.

When there is no jumper, usually the drive is assumed as single (only) or
Master. If you want to connect only the WD, you can try using it without
jumpers.

> It came with none. Also, is that something I could get at RadioShack?
If you need jumpers, and you can't find them on old HDs or PC parts (like
motherboards), I think you can find them in RadioShack, or
electronic/computer shops.

MDD Can not find Boot Disk

2011-07-02 Thread gifutiger
Greetings,

I've given up researching this problem and hopping one of you may have
some suggestions.

I recently acquired a MDD: Hardware Overview:

  Model Name:   Power Mac G4
  Model Identifier: PowerMac3,6
  Processor Name:   PowerPC G4  (3.3)
  Processor Speed:  1.25 GHz
  Number Of CPUs:   2
  L2 Cache (per CPU):   256 KB
  L3 Cache (per CPU):   1 MB
  Memory:   2 GB
  Bus Speed:167 MHz
  Boot ROM Version: 4.4.8f2
  Serial Number (system):
  Sales Order Number:
  Hardware UUID:--1000-8000-000393AE8678

and my problem is that if I preform a PRAM reset at boot time I get
the blank screen with the disk symbol and a ? (question mark)

This is true even if I have a "OS X 10.5 DVD" in the DVD Drive.
It's an over kill but I also have four (4) disks in the platform, 2
ea. IDE and 2 ea. SATA. The SATA drives are connected through a ACARD,
6280M which appears to the system as a SCSI interface.

All of the disks have a good system folder and can be use to boot the
MDD.
There are three (3) disk with OS X 10.5.X, one (1) disk with OS X
10.3.X and one (1) disk with OS 9.2.X.

Yes, if I remove all of the disks except one, the IDE (OS X 10.5.X)
which is located in the first disk position, the position where apple
puts the first disk when they sell you the platform the problem still
occurs.

When this problem occurs (my own doing) the only way out that I've
found to correct this situation  is to do a force shut-down, i.e. hold
down the power button until the system shuts down.

Upon re-powering the platform if I don't hold the "C" key, telling the
Boot ROM that I want to boot from the DVD I'm right back into the trap
of no Boot Disk found.

However holding down the "C" key the MDD will boot into the OS X 10.5
DVD "Commercial Version" at which time I can go the "Select Startup
Disk" and restart into any of my disk,

ABAIK the Boot ROM Version 4.4.8f2 is the latest version for this
platform, however it might have problems, so if anyone has knowledge
of how to redo the Boot ROM I'm willing to give it a try.

I have a disk with OS 9.2 installed so I could boot from that disk and
redo Boot ROM update, but I'm thinking that the install program will
see Version 4.4.8f2 and refuse to install.

Also if anyone knows the direct link to Apple to get the Boot ROM
please give it to me.

Cheers
