Set User Password
When the item "Set User Password" is highlighted, hit the key. When
prompted, type the user's password in the dialogue box to set or to change the
user's password, which allows access to the system at boot-up.
Fixed Disk Boot Sector
This setting may offer some protection against viruses when set to Write Protect,
which protects the boot sector on the hard drive from having a virus written to it.
The other option is Normal.
Password on Boot
If set to Enabled, a password is required for a user to enter the system at system
boot. The options are Enabled (password required) and Disabled (password not
required).
