Target Disk Mode: mess up

Ohenri · Aug 29th, 2003, 12:25 PM

Messed my TiBook up. Was in TDM with the Pismo and the Pismo hung up (Ti was the target). Was not asleep, was on - with a black screen. I was running hella late as I had a plane to catch so after not getting any response for over 15 mins, just disconnected. Yep. Bad move... but I had my fingers crossed. Once too many, my Ti will no longer start up. Tells me to restart, and will not restart holding C either.

Any ideas? Will likely bring this in...

H!

Are you running Mac OS 9 or Mac OS X?

If running Mac OS X, hold down command + s at boot and see if you can run fsck. Also, try booting up from a Mac OSX boot disk and run disk utility or some other third party application. Probably just the volume structures are messed up.

If OS 9, try the same thing, except the first part.

Try zapping the pram "option + command + p + r" at boot time. Wait for the boing, hold the key sequence down for a consecutive 2 boings (3 in total)

Try zapping the open firmware. "option + command + o + f" at boot up. Upon grey screen, type in reset-all, hit return and the machine will begin to reboot.

If you say it doesn't boot up from a CD when holding down the "c" key, what happens if you hold down the option key at boot time and go into the blue open firmware startup disk window? Can you then select the CD to boot from? Keep in mind you may have to hit the refresh button on the screen to get the CD to show up.

Finally, if all others don't work, remove the keyboard, and in the top right hand corner on your Tibook you will finda little reset button. That's the Power Management Unit (PMU). Hit the button once, wait for 5 seconds and then power on your machine and see what happens. Some of your preferences may have been blown away by resetting the PMU but not many. Most likely the date and time may be screwed up on it...

Hope these help...

This is the exact thing that I was doing that fried my IDE controller chip on my previous iBook's logic board. If all you get is a flashing folder or an inability to boot try this tip.

Find a friend that has a firewire harddrive. Install a universal OS 9 system folder onto it. (It's in the installer, under options or custom installation). Then try turning on the TiBook. If it boots from the external hd and nothing else you've probably got a fried chip.

Hope you get it working again.
