Mactron...Can you ask iMac600 to post the Modified ROM taken from the OS9General.dmg ?I think he did great work there, but dome newbies may be a little scared doing file Hex Edits...why re-invent the wheel if he can provide the modified ROM file.We can repackage and make a "Beta Test OS 9 General" for testing on unsupported models (that are close in hardware spec. to approved models)
well... I'm gonna try to contact iMac600 ...but I'm not optimistic about him posting the Modified ROM.In 68kMLA are extremely banned any kind of software sharing.Long time ago I've posted there a small app that I wrote by myself, and they were more worried about the license of the libraries I'd used than gimme to me the thanks for sharing my two months work. Thankfully everything was OK...
NONE OF THE G4 POWERMACS WITH A 7447A/B CPU CAN BOOT OS9 NATIVELY!
I heard from another user that Mac OS ROM can indeed affect drivers. I have yet to experience this myself. Albeit he claimed to have used a newer rom and from what I've gathered that 10.2.1 is the latest?
Yes, but this is more a Firmware restriction than a Mac Os 9/ Mac Os ROM problem. The 7447 and 7448 upgrades usually patch the Firmware not Mac Os 9/ Mac Os ROM to properly work.
Well, as promised here are the MacOS ROMs I have edited so far accordingly to 68KMLA instructions, I hope we now have enough material to experiment with :-)
Your files were destroyed by a zip compressor.
Would you mind trying to modify the 9.1.1 ROM? I can provide it for you if you need it. It's the one that comes with the CD I've used.
... only case I am aware of is the notorious set of modified ATI extensions that enable the use of Radeon 9250 cards under OS9, otherwise the GPU acceleration would not been enabled since the card ID is not recognized by OEM and retail drivers.

- Open the bundle by right-clicking (or control-clicking) on the PMG4FirmwareUpdate.app file inside /Applications/Utilities and choosing "Show Package Contents."- Navigate to Contents/Resources and drag the "Firmware" file to the root of your startup disk.- Make note of the partition number of your startup disk-- this is important for the next steps. On a freshly-formatted drive with OS 9 drivers, the first visible partition is 9, which in my case meant my second visible partition with OS X installed was partition number 10.- Reboot the Mac and hold down Command-Option-O-F to boot to Open Firmware.- Enter the following two commands, substituting your partition number after the "hd:" load hd:10,Firmware go- With luck, the white Open Firmware prompt will disappear and you'll soon see an OS 9-style progress bar at the bottom of the screen as the Boot ROM is being flashed.- After the Mac automatically restarts, install OS 9 using the special version for the MDD FW400 (OS9General.dmg). The OS 9 System Folder should be visible and selectable using the Startup Disk preference pane.- Enjoy.
-the success of the g5 booting os9 had nothing ABSOLUTELY nothing to do with a "mac so rom" file..so all this talk of rom file.. and installation medias.. + custer cds.. is all wasted time + effort
...Give me a Mac Os 9 ROM with support for the G5 motherboard components and the Firmware/Open Firmware tricks will be a little walk in the park on a sunny day .... LOL
For example, in a discussion on the apple support forums I found a Sawtooth owner who had a corrupt boot rom who wanted to reflash it with a fresh copy of the firmware. He stated that Sonnet sent him a utility he called the G4 ROM Utility that had the ability to both save a copy of the boot rom and reflash it -- (https://68kmla.org/forums/index.php?/topic/5527-macos-86-on-sawtooth-g4/page-2)
There is a utility called PM G4 ROM UTILITY (the guys from SONNET sent it to me) what can read out & write a G4 firmware. https://discussions.apple.com/thread/536041?start=0&tstart=0
we are used to [command] [values] [switches]and this language's structure, as illusrtated in the above quote...is set up like this: [values] [command]totally backward http://macos9lives.com/smforum/index.php?topic=762.msg4676#msg4676
I know people with OS9-compatible iLamps. If software can be provided I'm sure I can get them to do firmware dumps.
Like me? I'll have a look at it if someone can provide the software needed.
Wait? What? What's new? I've got a non-os9 compatible imac. I can hack OS9 into it but without proper sound and graphics support.

this is because u dont have the proper firmware on it yet!!!!!! i really believe that we can solve this though.

When shipped, these models were configured with MacOS X 10.2.3 pre-installed and neither can boot into earlier versions of the MacOS. Each can run MacOS 9 applications within the "Classic Environment" provided by MacOS X 10.4.11 and earlier, however.
cloaked alien: i think it migth be worthwhile to find the imac g4 restore cds that have 10.2.3 on them.. and then try the mac os rom trick again.
Edit: It's the Mac OS ROM from OS 9 that's the file you mod. It's version should not be confused with the OS version. Where should we find that on the OS X cd? ^^I THINK I hunted down the restore CD from the supported G4 iLamp and had the OS 9 rom modified.
ok!!!!ive located the "mac os x install cd" for the imac g4 800mhz .. presumably the "x only" model..downloading now and i will open the sucker up and try to find the mac os rom hidden deep within if it even includes the os9 system folder.. did they stop including os9 in 2003?
I'm not following this thread. But, you are trying to boot a iMac G4 800 in Mac os 9?

what im talking about is a utility that allows u to save the original firmware for doing just such a patch....it reads the firmware + saves it to a file... enabling the user to be able to restore their original firmware in the event thatthe cpu is uninstalled.this is the utility to be used to take the mac os 9 bootable firmware from os9 bootable version of the imac g4 product lineto be able to attempt to take this firmware + write it to the 800mhz X only imac g4 (which has the same motherboard as the other 9 booting lowend models of imac g4)and.. for someone brave enough.. to try this on the models that followed that had a significantly different motherboard (at a risk) to gain os9 bootability.newertech + powerlogic + sonnet are all said to have these types of "rom saving" utilities to facilitate patching + unpatching for 3rd party cputhe software packages that came with these 3rd party cpus is where someone needs to look to find this or possibly a download from a web backup of their sites.
The Apple iMac G4/800 - X Only (15 inch Flat Panel) is te easiest to boot into Mac Os 9 again ... LOL
