I'm stumped. <br><br>

I have the EXACT same problem.<br><br>Did you find a fix?<br><br>

Yeah I did. First disconnect any peripheral devices - including all USB devices (obviously, leave the keyboard & mouse plugged in, but that's all).<br><br>Then open up the case and if you have a slave HD, disconnect that - to do this, just remove the ribbon cable, there's no need to disconnect the drive's power.<br><br>Then disconnect the main HD - to do this, again just remove the ribbon cable, there's no need to disconnect the drive's power.<br><br>Then startup the machine from an OS9 CD. If it boots OK (as mine did), reconnect the main HD and try it again. My G4 was OK from here on in, so if this doesn't work for you, I don't think I can help.<br><br>Good luck!<br><br>

Ditto. No Boot OS 9.<br>Mirror Door, Dual 867, OS 10.3, will not boot from OS9.2.2 on CD or HD. Two internal drives; 60GB Seagate Ultra ATA IV & 160GB Maxtor. Eventually got OS9.2.2 installed on Maxtor. Will not boot from it or a CD (Superdrive DVR-106). Removed PCI cards (Sweet Multiport, SCSI, ATI Rage) and disconnected both HDs, still will not start from CD in 9. Dang.<br><br><br>

Was it the 9.2.2 CD that came with the machine?<br><br>

No, I have been trying to use a copy of a PowerBook G4 install disc. I bought the machine used with a retail boxed 10.3. I just noticed that according to the "build label" that this MDD was sold with OSX installed. I was told at MacOSX.com that the Mirror Drive Door machines will not boot from 9. I'm not so sure as I believe it was marketed as the last dual boot machine, and it is not listed on the "Only start in X list" here: http://docs.info.apple.com/article.html?artnum=86209.<br><br>After reading your question I tried from a Norton Utilities 8 disc, (has both 10 & 9) and it started in 9.2 "version OSZ1-9.2.2" perhaps there is hope yet, and my problem is the correct install disc.<br><br>Thanks,<br>Mark<br><br><br><br>

If the MDD has three Firewire ports it won't boot to 9.<br><br>The MDD didn't come with a 9.2.2 install disk, you have to restore from the original CD's to get the correct System Folder. The 9.2.2 on it is a special one for the MDD, it needs it to to be fully functional.<br><br>Or do a find for an invisible folder called .images on the first or second MDD restore CD and look for the OS 9 General disk image in it. Copy it to the HD. It's not an installer, it has the 9.2.2 System Folder and a few other parts on it.<br><br><br>

Thanks for the info. We have two Firewire ports. I may have a source for a correct CD. I have no original disks with this machine, only a retail 10.3.<br>Mark<br><br>

I have a very similar problem. My G4 quicksilver 2002 will boot into OS x fine, however, I am unable to boot into OS 9.2.2 even with the disk. I am almost positive that this is the disk that came with the computer to begin with, and looking at the charts it seems as though the 9.2.2 should work with this particular computer. I have tried zapping the pram and even tried to do a clean install and the computer keeps getting stuck on that annoying grey screen. Any other help would be greatly appreciated.<br><br>

Do you have a part number for the CD set on your Quicksilver? <br>It may not be bootable, some Restore and Install CDs are bootable, and others are not. Here is a link that may be usefull:<br>http://docs.info.apple.com/article.html?artnum=106294#m9<br><br>I have read the PowerMac G4 Software CD (for the MDD at least) is Apple P/N: 691-4078/4103/3548/3600-A, & disc 1 is labeled 691-4078-A, & disc 2-4, labeled 2Z691-4103-A <br><br>Mark<br>(still working toward for a dual boot, dual 867)<br><br><br><br><br>
