Write-protecting a diskette
A diskette can be write-protected by sliding a small tab towards
the edge of the diskette to expose the little hole beneath it
(see diagram). With the tab in this position, you can read, copy
or print files from the diskette, but you cannot create, rename
or delete any files.
PROTECTED
UNPROTECTED
The BIOS Setup utility can disable the diskette drive, or make
it read-only.
Using the BIOS Setup utility
What is BIOS?
BIOS (pronounced “bye-oss”) stands for basic input/output
system. The BIOS operates at the boundary between the
computer’s hardware (the system processor, memory, diskette
and hard disk drives, and so on) and its software (the operating
system and applications), and effectively mediates between the
two. The BIOS is permanently encoded in an area of read-only
memory (ROM), although it can be modified if necessary by an
authorized maintainer.
What is BIOS Setup?
BIOS Setup is a utility programmed into the computer’s BIOS
ROM. Its main purpose is to allow you to view and alter your
computer’s configuration. BIOS Setup is also used to configure
the on-board security system.
