Failed to initialize HAL - No internet, cd or usb

[Alex Mandel]

So I was trying to configure a scanner and I used synaptic to install 
usbmgr.

This unistalled hal, gonme-volume-manager, hotplug etc. (Didn't quite 
realize what I was doing)

So I go to boot up the machine to work on it today and I get a "Failed 
to initialize HAL" with a haywire usb mouse, no ethernet and no cdrom.

How do I undo the damage, I know I need to reinstall HAL etc. but I 
can't access the cd or the internet to get the package.

Help,
Alex
