Booting a CD / Special password protection

[Volker Augustin]

Hello, I have 2 questions:
1. Is there a way to use GRUB to boot a bootable CD?
2. Is it possible to specify in the menu.lst a password for each menu entry 
that is asked for AFTER the entry is selected? for example if the first line 
for a menu entry is "password abcd" grub should ask the user for  password and 
redisplay the menu if a wrong password is given. optionally the password should 
not be stored in the clear but only the hash of the password.
