Help! Pismo booting to command line?

[MacMagus]

'First thing to try is a simple PRAM zap.

Hold down ++P+R on startup and wait for 3 chimes.

Then see if it boots normally.

If it doesn't then try booting with an install CD and run the Disk Utility to repair the disk.

If the Disk Utility finds nothing wrong or repairs something and you still can't boot then an Archive and Install might be in order.

If it finds something wrong and can't fix it then we can talk about other solutions.

BTW: It shouldn't be locking up all that often. You've got another problem to take care of once you get it booting.
