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 or stored on your hard
disk.
Note:
This switch does not affect the ability to read information from a diskette.
Before you begin:
Ÿ
Read “Safety information” on page vii and “Handling static-sensitive
devices” on page 57.
Ÿ
Turn off the computer and all other connected devices.
Ÿ
Disconnect all power cords and external cables attached to the
computer, and then remove the computer cover (see “Removing the
cover” on page 59).
1. Locate the small rocker switch on the system board. See “Identifying
parts on the system board” on page 65. It might be helpful to use a
small screwdriver or ballpoint pen 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.
Working with memory
You can add memory to your computer to increase system performance.
Your computer has two connectors for installing memory modules that
provide up to a maximum of 512 MB of system SDRAM.
Your computer uses dual inline memory modules (DIMMs). The
IBM-installed DIMMs that come with your computer are unbuffered,
synchronous dynamic random access memory (SDRAM).
When installing or replacing DIMMs, the following rules apply:
Ÿ
Fill each system memory connector sequentially, starting at DIMM 0.
Ÿ
Use only 3.3 V, 133 MHz, unbuffered, SDRAM DIMMs.
