Setting the diskette write-protect switch
The diskette write-protect switch controls whether you can write
information to a diskette using a diskette drive. The ability to prevent
writing to a diskette is particularly useful if you are concerned about the
security of information that can be obtained through a network.
Note:
This switch does not affect the ability to read information from a diskette.
Before you begin:
Ÿ
Read “Safety information” on page ix and “Handling
static-sensitive devices” on page 61.
Ÿ
Turn off the computer and all other connected devices.
Ÿ
Disconnect all cables attached to the computer and remove the
computer cover (see “Removing the cover — tower model” on
page 68 or “Removing the cover — desktop model” on page 64).
1. Locate the small rocker switch on the system board. See the label
inside the computer or “Identifying parts on the system board” on
page 74. It might be helpful to use a small screwdriver to set the
switch.
2. Set the switch as follows:
Ÿ
For read-only diskette operation, set switch 1 to the ON position.
Write-protect is now enabled.
Ÿ
For normal diskette operation, set switch 1 to the OFF position.
Write-protect is now disabled.
