now what?

ps i also have a 10.2.3 update disk but stalled whilst running teh installer as well.

any suggestion on cause, workaround, how to correct?

Is the date on the machine correct? If not it may have a flat PRAM battery.

DiskWarrior gave a "keys out of order" error? Did it manage to fix the disk?

Try booting in verbose mode by holding down command-v while rebooting. This may reveal a message about what's going wrong. Also try shift booting (rebooting with the shift key held down). If this works then you know it's some kernel extension causing the problem.

Have fun,
Shay
