Resetting the CMOS Clock RAM for Valdocs This technical information is provided by Epson Systems Product Support Group. While it should prove useful to you we cannot guarantee that it will hold true in every instance. The Valdocs system stores certain crucial information in CMOS Clock memory which is kept accurate by a NiCad battery when the computer is turned off. But if the NiCad battery is not properly charged, the data that is in the CMOS Clock memory may become corrupted or even lost. If this should happen, the Valdocs software will very likely malfunction. By using the following procedure you will cause Valdocs to reinitialize all its data in the CMOS Clock memory and thereby make Valdocs operate correctly again. This procedure assumes that you know how to get into and out of Zapple. If you do not know how to get into Zapple, use the instructions in either paper titled "Zapple Access from Valdocs 1.1x, Hardware Method", "Zapple Access from Valdocs 1.1x, Software Method", or "Zapple Access from Valdocs 2". When entering the Zapple commands in steps 2 and 3, it is not significant whether the letters are in upper or lower case. What is important for both of the Zapple commands is that the second character entered is the letter "oh" (o) and the last character entered is the digit "zero" (0). If at any time the command is entered incorrectly, Zapple will display an asterisk. If that happens, simply re-enter the command again correctly. 1. Get into Zapple. 2. At the Zapple prompt enter the following: co3e,0 3. Now enter: co3f,0 4. Get out of Zapple. 5. Press the reset button. The reset button is located on the front of the computer below the right disk drive. 6. When the screen displays a message about initializing cold start defaults press RETURN. 1 87.7.15 7. Valdocs will now load like it normally does, however, you will have to go through the Valdocs setup, since all SETUP values have been changed to their default values. Now that you have reset all the CMOS Clock values, please leave your QX computer plugged in and turned on for at least 24 hours to insure that the NiCad battery will become fully charged. 2 87.7.15
