Copland

[mrintel]

I guess D11E4 only works on the 1st generation of Power Macs, cause that's all I've ever seen it work on successfully.

Well, I guess I need to get a 6100. Can't wait...!

Anyone else got it to work on their macs?

[protocol7]

I wonder would it work on a 5400? That's the only Mac I have close enough and I don't think I've ever tried it.

with Drive Setup 1.0.4 or later).

For builds up to and including DR1, the installer is set to
ensure you have System 7.5 or later on a hard disk 250MB or greater.

Monitors connected to either built-in video or a
card set to 256 colors (8-bit) or Thousands (16-bit).

there is also D7E1 build (Maxwell) ... didn't tried it yet

•  *** Very Important *** Copy your scarecrow disk image to another volume, the scarecrow volume will get corrupted over the course of a few test runs.

•  *** Very Important *** If you get a message like 'core resources: assertion failed,' replace your finder due to its corrupted resource fork.

• Make disk first aid a startup item, and repair it every time you boot into the conventional system.

[protocol7]

D7E1 needs another PowerMac connected as a debugger. D11E4 didn't which is why you're more likely to see it running.

Chances are some unsupported macs might be able to boot Copland, but I think the problem for me is the 5400 uses IDE for the internal drive.

The readme from the D7E1 build (Maxwell) sounds scary. I was expecting for the next line to say you should keep a fire extinguisher next to your Computer at all times when using this build.

On Taligent to quote Aaron Hillegass from the Big Nerd Ranch:

Once upon a time, there was a company called Taligent. Taligent was created by IBM and Apple to develop a set of tools and libraries like Cocoa. About the time Taligent reached the peak of its mindshare, I met one of its engineers at a trade show. I asked him to create a simple application for me: A window would appear with a button, and when the button was clicked, the words "Hello, World!" would appear in the text field. The engineer created a project and started subclassing madly: subclassing the window and the button and the event handler. Then he started generating code: dozens of lines to get the button and the text field on to the window. After 45 minutes, I had to leave. The app still did not work. That day, I knew that the company was doomed. A couple of years later, Taligent quietly closed its doors forever.

The Secrets of Pink, Taligent and Copland

[mrintel]

As far as the documentation goes, D7E1 / Maxwell only works on the 1st gen Power Macs, and I have yet to see any working demos of it.

[protocol7]

Ok, I tried to install Copland, and everything went fine, until the kernel tried to initialize. Then the debugger gave this error...

Access Fault

Kernel: Dispatcher: No kernel stacks available!


Does anybody have any idea as to what I'm doing wrong, if anything at all?

I also encountered this trying to install onto a 7500. It seems to have a RAM ceiling. I had 96MB installed. Dropping it down to 32MB fixed this and it booted fine.

[mrintel]

Hmm...    
...I'm going to try that on friday. If it works, I will be forever indebted to you...

[protocol7]

Did you have any success? It worked for me on the 7500. Wasn't very stable though.

[mrintel]

Oh...I'm so sorry I didn't reply much earlier. I've been quite busy lately, but I did find time to remove some RAM and it did indeed work. But, the kernal kept crashing on me, so I always had to have a 2nd mac plugged in through a serial port to tell the kernal to continue. Again, sorry it took me so long to respond. I completely forgot about it.  :oops:

[protocol7]

One thing I did find was that if I had the debugger attached when installing, I had to keep it attached if I wanted D11E4 to boot. But if I installed without having a debugger attached, it would boot fine without it. But even with the debugger attached it's not particularly stable. Just fun to be able to see it up and running.

[mrintel]

True. And I was looking through some old documentation I have, and I noticed that different models of macs had different maximum memory ammounts. I'm trying to see if I still have that paper.

[protocol7]

Yup the "DDK 0.4 Read Me First!" file lists the configs D11E4 was tested under:

Code Select Expand

6100/66MHz/24MB          7100/80MHz/40MB          8100/110MHz/24MB
6100/60MHz/48MB          7100/80MHz/24MB          8100/100MHz/24MB
6100/60MHz/16MB          7100/80MHz/16MB          8100/80MHz/24MB
                        7100/66MHz/24MB

7200/90MHz/16MB          8500/120MHz/40MB         9500/132MHz/32MB
7200/75MHz/24MB          8500/120MHz/24MB         9500/132MHz/24MB
                                                 9500/120MHz/24MB
7500/100MHz/32MB                                  9500/120MHz/16MB
7500/100MHz/24MB
7500/100MHz/16MB
In my case it was a 7500 with 32MB RAM and a 150MHz 604 upgrade.

Actually that's something else to remember: Copland apparently won't work on a 604e or 604ev, only a vanilla 604.
