The 20 in the first two examples tell you which chip in the bank that is which bit in the 8 bit data byte is failing Look at Figure 4 1 the fourth chip from the top of each memory bank is numbered 20 An error code of 4020 or 40000 20 means that the fourth chip the chip numbered 20 in Figure 4 1 from the top of the fourth memory bank in the PC is failing If you have a PC with 256 KB Banks 0 through 3 installed on its system board Bank 4 would be the first bank on the SixPakPlus board The 201 in the error message indicates that there is a probiem in memory Once you determine which chip you believe is causing the problem replace it with a spare chip and see if the error is corrected you can tell that the error is corrected when you reboot your PC and it does not display an error message If no spare chip is available try exchanging the suspect chip with another one in the same bank which is not failing If the error then moves to the new socket you definitely have a bad chip If the 4 11 Advanced Configuration error persists at the original socket you may have a problem with the board contact your dealer for assistance If you get an error message such as 40000 S 201 it tells you that you have a memory problem in Bank 4 in your PC the S simply means that the falling chip is somewhere in the system unit that is somewhere in your computer The best way to isolate the problem chip is to swap eac
