“Display Adapter.” Notice that selecting the type of diskette drive is not an option. The T3300SL automatically deter- mines what type of internal diskette drive is installed. Also, you don’t have to run the SETUP function to use an external 5.25-inch diskette drive.
Follow these steps to set all the SETUP options to their default settings. Press Home. This instructs the program to reset all the options to their default settings. The program calculates how much base and extended memory your T3300SL has based on whether or not you have an expansion memory card installed.
The SETUP screen is divided into functionally-related groups. This section describes each group and the available options. MEMORY This group of options displays the configuration of the memory installed in the T3300SL. Certain options allow you to configure the memory you install in the T3300SL. TOTAL This field displays the total amount of memory installed which is automatically calculated by the computer.
Page 100
Hard RAM. HARD RAM Use this option to create a Hard RAM disk in the T3300SL’s memory. To configure the Hard RAM, you can choose the size of the Hard RAM in 512KB increments. The amount of memory you can allocate for the Hard RAM depends on the size of the extended memory installed in the T3300SL.
Page 101
This option displays the size and type of hard disk installed in the T3300SL. POWER ON PASSWORD This option allows you to enable or disable the password required for the T3300SL to power on and allow access to the C prompt.

For example, if you enter a password consisting of four characters, the display is shown as: Password = **** NOTE: If you press Enter before entering the password, Not Registered will appear on the display.
Page 103
HOW TO ENABLE THE PASSWORD. MAKING A PASSWORD SERVICE DISK The T3300SL provides a special feature that uses the Password Service Disk to unlock the password. To create the Password Service Disk, prepare a formatted 3.5-inch 2DD floppy disk (any data on the disk will be erased) and follow the steps below.
Page 104
NOTE: You can assign a COM level only once. For example, the Serial Port and Card Modem options cannot both be assigned to COM1. CARD MODEM POWER If a card modem is installed in the T3300SL, this option appears. It assigns power to the modem. Supplies power to the card modem.
Page 105

General This chapter explains how to disassemble and assemble the T3300SL to replace the Field Replace- able Units (FRUs). It is not always necessary to remove all the FRUs in order to replace one. The chart below is a guide to which FRUs need to be removed so you can replace the one that is causing the T3300SL to operate abnormally.
Review the procedures in this section and familiarize yourself with the steps required to disas- semble and assemble the T3300SL. Begin each procedure by removing the AC adapter and the battery pack as instructed in Section 4.2, Battery Pack, and remember the following points: Do not disassemble the T3300SL unless it is operating abnormally.
4.1.3 Reassembly Procedures After you have disassembled the T3300SL and fixed or replaced the FRU, you will need to reas- semble the T3300SL. While assembling the T3300SL remember the following general points: Take your time and make sure you follow the reassembly instructions closely.
Proper use of ESD devices will increase the success rate of your repairs and lower the cost of damaged or destroyed parts and FRUs. The following equipment is necessary to disassemble and reassemble the T3300SL: One 2mm Phillips-head screwdriver to remove and replace screws...
Battery Pack The battery pack is always the first FRU you should remove when you disassemble the T3300SL. This is done as a safety precaution so you do not get an electric shock as you are disassembling or reassembling the computer.
Make sure the arrow on the battery pack is pointing up. Then align the battery pack with the battery pack slot in the T3300SL. Slide the battery pack into the battery slot until it is flush with the side of the T3300SL case (Figure 4-2).
Optional Memory and Card Modem 4.3.1 Removing the Optional Memory Card and Card Modem Turn off the power to the T3300SL. Disconnect the AC adapter and all external cables connected to the T3300SL. Remove the battery pack as instructed in Section 4.2.
