View Full Version : sick g4 450dp, wont boot

02-22-2001, 07:37 AM
system wont recognize any of the internal drives. on startup, the old flashing question mark keeps flashing for 10 mins plus until i turn the machine off. I have tried the restore cd in the dvd rom, a system folder on a zip, both at the same time, holding the c key down.....any suggestions? seems to me that the ide bus is shot.

Try disconnecting all drives except the CD and then try to startup.

tried that, the drive light comes on for a second and then goes out. repeats this process every minute or so. but no startup

I would pull all devices, inspect the jumpers, and reinstall them one at a time.

hopefully a jumper fell off....or your Mac was misconfigured at some point.

what started all this?

1. could not load cds that friends g4 400 could load
2. tried to boot os9 from cd, but there was some conflict
3. decided to try and change system folder by dragging new folder from os 9 cd to HD, change the name of the old system folder and boot from the new folder
4. THE END. blinking question mark for days

Your step 3 is certainly not the way to get a fresh system folder. I'd say your HD needs to be reinitialized.

If you can't boot from the OS CD with ALL other drives disconnected as we advised earlier, then you must have a hardware problem.

Man, why don't you give that info in you initial post??
The System Folder on the OS CD is an abbreviated version missing many of the resources you need to run a full system off a hard drive in the computer. You need to get a proper system back on that hard drive.

you need to find the CD that came with your Mac, or buy a new OS9.1 CD-ROM from Apple, so you can boot off that. Once that's done, throw away the system folder you dragged onto the drive, and do a clean-install of MacOS 9.1.

it might be a good idea to tell us which Mac you own.

model. g4 450 dp

a compusa guy gave me an 9.04 os restore cd but that didn't work. is this any different than 9.1 regular version?

02-25-2001, 07:37 PM
probably. Your Mac may require resources which are not present on the restore CD.

a 9.1 system CD should boot all current Macs, and all legacy Macs compatible with OS9.1.

The restore cd are machine specific. Do you know what machine he pulled it from?

Find the cd that came with your machine and boot off that and do a clean install.
