Just got myself this new MDD FW800 Dual 1.25 today, however having put the HD of my old MDD Dual 867 in (10.2.6), I can't get it to boot off it...That boot HD was previously working just fine in that MDD Dual 867 and prior to that on the QS G4/800, where I essentially first installed OS X on...Any ideas on what's happening here? I've heard that that's a common issue with some of the new Duals, any way to rectify this without installing a new OS X?

Just a FYI I already reset the PRAM 3 times...The weird thing about this situation is that within the Startup Disk option of the Preference pane, using a 10.2.3 on another HD I can select the original HD (10.2.6) as a boot volume, however upon restart it automatically reverts itself back to the 10.2.3 HD...Pressing option at boot time also reveals just the 10.2.3 HD as a boot volume, no sign of the 10.2.6 HD...

I've tried all the possible combinations (a.k.a leaving the 10.2.6 HD on the ATA66 channel alone, leaving it on the ATA100 channel alone etc)...no go..

Make sure you have the jumpers on the HD set to let the bus chose weather or not it's a master or slave drive.

It might have something to do with the fact that the dual-867s were still System 9 bootable and the new dual-1.25GHz is not. I'm not sure how that is actually implemented but it may be something that the 1.25 needs to boot is not installed on your old drive.

The jumpers should be set to cable select, but they would have been that way in the 867 as well.

I'm not surprised... the new machine has different/newer firmware than the old one. What happened to the drive that came *in* the new machine? Boot off that, and use the old one as a data disk. You won't be able to have the old drive boot the new machine -- the drivers aren't the same.

FYI: I have 10.2.3 retail CDs, and my new PowerMac 1.25ghz won't boot from them because the software restore DVD is a newer version.
