User`s guide

If you select Supervisor for this option (the default setting),
you can access the diskette drives only if you enter the
Supervisor password when you start your system. If you start
the system with a User password, you see an error message
when you try to access the diskette drive. If you select User
for the Diskette access option, you can access the
diskette drives whether you enter the Supervisor or User
password when you start the system.
Note
To use passwords for diskette drive access, you must enable
the Password on boot option. If you select a password
level for Diskette access, but leave the Password
on boot option disabled, you see an error message
whenever you try to access your diskette drive.
You can also protect your system by selecting Write
protect for the Fixed disk boot sector option.
When this option is enabled, the system displays an error
message when a program tries to write to the boot sector of
your hard disk drive. The boot sector is where computer
viruses typically cause damage. To use a program designed to
write to the boot sector (such as the Format command), you
must select Normal (the default setting) for the Fixed
disk boot sector option.
