Set User Password
When the item "Set User Password" is highlighted, hit the <Enter> 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).
