IMPORTANT: If you are planning to run an alternate operating system (e.g., OS/2 or UNIX), you will need to configure the system using the Compaq Diagnostics diskette, which can be obtained from Compaq (see Chapter 3). Failure to configure the system can result in loss of data and reduced hard drive capacity.
Page 50: Preparing The Computer
2.3.1 Preparing the Computer If you encounter an error condition, complete the following steps before starting problem isolation procedures: 1. Ensure proper ventilation. The computer should have a 3-inch (7.6-cm) clearance at the back of the system unit. 2. Turn off the computer and peripheral devices. CAUTION: Always ensure that the power is off before disconnecting or reconnecting the mouse, keyboard, or any other peripheral devices.
