What I would also try, is, if you can still go into Open Firmware. Hold Cmd-
Opt-O-F pressed when you hear the chime, until you see the Open Firmware
screen (which will tell you, that you can now let go of the keys you should
still be holding at this point).
If you can use your keyboard normally there, the computer should be fine.
Try commands like:
devalias
cd /
ls
.properties
To continue booting, type:
mac-boot
To boot a CD-ROM, type:
boot cd:
After hitting enter, you can then quickly hold the Opt key if you want to get
the boot menu to choose where to boot from.

How do you figure?
So you can run Applejack?
And you can start-up in single user mode?

After trying if Open Firmware still works for me, I'd zap the PRAM: Hold Cmd-
Opt-P-R at the chime. I normally do this at least twice (keep the keys pressed
until you hear the third chime, then let go).
This /could/ solve the problem, but I'm not very sure of it.
> Could this hang cause any possible problems with the HDD?
Yes. Could be your hard drive, or the installation on it.
But then you shouldn't have these problems when booting form CD.
To be absolutely sure I'd remove the HDD and boot from CD. If that works, you
propably have a broken HDD.
