Mac OS 9 booting on: Mac mini G4 (Detailed Posts)

<< < (2/311) > >>

Custos:
Just got a 1.25GHz model. There has got to be some way of getting it to boot os9.  :-\

4 Models with 7447a proc.

http://www.everymac.com/systems/apple/mac_mini/specs/mac_mini_g4_1.5.html

The first 3 have 32 and the last 64 Mb of RAM in the same ATI 9200 that is the last ATI (at least the PCI one) that has Mac OS 9 drivers.

As MacTron said, it should need some open firmware commands to allow those 7447a proc. run in 9.

Is the northbridge, MPX, MaxBuss chipset the same than on MDD/iMac G4?

The northbridge/chipset in the mac mini is the same that was used in the G4 iBook and All but the last revision of the G4 PowerBooks.
It's the Intrepid chip.

Hello everyone, forum newbie here.

I just recently bought a G4 mini because of the work you guys are doing here.   :)  It's the 1.33Ghz model, with the original restore discs (10.4.2).  I'm willing to assist in testing things on my mini as I have time.

Very selfless -- thank you!

These are some instructions that a person with an Ethernet-connected unsupported machine can follow to produce an embarrassment of debug output.

Download and burn the "Unsupported G4" image from here: http://macos9lives.com/smforum/index.php?topic=2143.0. I have instructed one user, by private message, to use an image that was probably not going to work. My apologies to that user.

Start the test machine with cmd-opt-O-F held down, until you reach the Open Firmware prompt. Choose an IP address that is on your local network but preferably outside your router's DHCP assignment range. The address 192.168.0.255 is a safe bet, and I will use it in this example. Enter the Open Firmware command (including the oddly-placed spaces):

--- Code: ---" enet:telnet,192.168.0.255" io
--- End code ---

On a separate OS X or Linux machine, open a terminal and Telnet into the test machine with this command:

--- Code: ---telnet 192.168.0.255
--- End code ---

Then, enter these commands into your terminal:

--- Code: ---dev /
.properties
5303ffff encode-int " AAPL,debug" property
boot cd:,\\tbxi
--- End code ---

And post the output! (Or use a pastebin-like service if you think it's too long for the forum.)
