INSTALLATION

3.Return the keyboard to its normal position on top of the keyboard support posts.

The card is now ready to be tested.

Testing The Card

1.Attach the video cable from your monitor to the //c. Attach the external power supply cable to the //c. Turn on the monitor. If you did not insert the backup copy of the Utility side of the MultiRam disk into the internal disk drive, do so now.

2.Turn on the //c. BE CAREFUl! DO NOT TOUCH ANYTHING INTERNALLY IN THE //C

OR YOU MAY RECEIVE AN ELECTRICAL SHOCK.

3.Check the boot action. After the disk drive stops, you should see a menu appear on screen if the card is seated correctly.

If instead you see a blank screen or lines or blocks of inverse characters on screen, then you have probably not correctly inserted the card. If you see a blank screen, first check your monitor to be certain it is on and then check to see that the video cable is properly connected.

If the monitor is correctly set—up and the screen remains blank or if lines or blocks are on screen, turn off the computer and disconnect the power cable. Place the keyboard back on top of the disk drive and check the card.

Try rocking the card further into the motherboard sockets. Also check the CPU and MMU components and the RAM chips. If the pins of these components sees to be inserted correctly no pins out of the socket or bent under the socket — press down on them to be certain good contact is being made. Check to be certain that the notches of the RAM chips face the top of the card and the notches of the CPU and MMU face to the left toward the RAM chips.

Test the card again. Try the preceeding steps again if you do not succeed. If you cannot get the card to work after repeated attempts, contact your dealer or Checkmate Technology for assistance.

4.Assuming a normal boot did occur, select the RAM teat diagnostic from the Utility menu. Refer to Chapter 3 for detailed information on how to use the RAM test and what to do if RAM does not test good.

If RAM on the card tests good, you are now ready to reassemble the //c. Turn off the computer and remove the external power supply cable and the video cable from the back of the //c.
