P87C52SBAA IS NOT GETTING DOWLOADED FROM THE BUFFER OF TOPMAX II PROGRAMMER. SHOWING ERROR "PROGRAM ERROR, CHIP ADDRESS 0000000h data 00h, checksum 0000000h, data 02h. At first we loaded from another P87C52 programmed microcontroller which has A12Dh. But the buffer is not getting copied and showing the above error. Please advice us so that we can copy the data and use the microcontroller properly. Regards, Arup Roy

I personally would give it a try ;-)
Since you can't do anything with it now, it wo'n't get worse anyway.

You would be surpised how many problems can be solved by logical thinking and acting without fear for failure.

tosrisri hello,

If you have a VISTA DVD, please insert it, and use the BIOS to boot through your CD.
Then, when the VISTA installation comes up, press repair. Restart, and try again. Please report back.

CHECKSUM CANNOT MOVE COMPUTER FROM A BLUE SCREEN


In order to understand what a checksum error is, it is important to first learn what a checksum is. A checksum is a redundancy check during a computer's start up process, which makes sure that the computer's data is intact and unhampered. The data is scanned and tested for accuracy, either based on how well it relates to data elsewhere or based on previous data that was stored on the same computer. Essentially, all of the bits of data in a particular document or file are added up and a number or hash is created. This number or hash can then be compared to the number or hash generated from the same file on another person's computer or at a previous time on the same computer.
When does a Checksum Error Occur?

Although a checksum error can occur at any time while a computer is comparing data, it is most commonly present during a computer's startup procedure. During a computer's start up processes, the BIOS settings, which are stored in a CMOS memory chip, are computed and then checked against the previous value. If the computed values do not match exactly, the computer warns the user with a checksum error message that the data may have been changed or corrupted between start up cycles. All BIOS programs present a different error and therefore will either continue with booting or refuse to boot until the problem is corrected.

Depending on the type and the severity of the error generated, there may be one of a variety of ways to rectify the issue. The most common cause of a checksum error during the startup process is a faulty battery that is not providing sufficient power to the motherboard when the computer is off. However, motherboard malfunctions and viruses can also contribute to checksum errors.
Other Types of Checksum Errors

Another type of checksum error may occur with any program at any time. It is usual for many programs to now provide checksum information when that program is downloaded. Using a checksum program or MD5 hash checker, a user can quickly compare the checksum of a downloaded program with the checksum that the software developer provides. This is a common way to make sure that users are downloading the proper program and that no data was corrupted during the download process. Checksum errors originating from download errors can easily be corrected by re-downloading the problematic program.

How to programme an eprom


There are three special "Enable" pins on the EEPROM: CE (Chip Enable), OE (Output Enable), and WE (Write Enable). CE simply activates the chip (if CE is not enabled, the EEPROM will do nothing). OE makes the chip output a byte, and WE makes the chip program a byte into itself. When you are programming an EEPROM, you want to keep CE enabled the whole time, so tie CE low. (Because all three of these Enable signals are active-low; At least, they are on the 2865.) You also want to keep OE disabled the entire time, because you are not having the EEPROM output any bytes; Rather, you are programming bytes into it, so leave OE disabled: If it is active-low, tie it high to disable it. That leaves WE; Leave WE disabled for now.

The next thing you need to do is turn your EEPROM on. Connect its power pins to a power supply. (For the 2865 chip, that would be pins 14 and 28.)

The biggest step is to actually program the byte. First, configure the EEPROM's address and data buses to indicate the byte you would like to store, and the address you want to store it in. For example, to store the value 80 in the very first byte of the EEPROM (which is address 0), you'd tie all the address bus pins low (which means logical zero), so the address is set to 0. Then you'd set the data bus pins to the binary representation of 80, which is 01010000. Remember that bit numbers are read from right to left, not from left to right, so in this example, the first four data bus pins should be 0. (The second data bus pin should NOT be 1; Only the fifth and seventh will be 1.)

Once you have set up the address and data buses, the only thing left to do is cycle the WE pin to actually write the byte. Send WE low for a moment (assuming it is active-low), then put it high again. If the EEPROM is working properly, you have now stored your byte, and you can later examine it with OE. On the 2865 (and many other EEPROMs), there is a READY/BUSY pin, which is an output from the EEPROM which indicates when the chip has finished writing to itself and is ready to accept more input

3 bleeps when i boot up acer aspire 9300


This means that your graphics chip is pootched. Since the graphics card is usually fixed to the motherboard the only way to repair is to take it in for service. Since the service may be ½ the cost of a new laptop it may be best to just purchase a new one.

Make sure you fixed the HDD properly..In some cases you need to push a little harder. See if any pins had been bent, if so straighten it, without breaking it.

Blue patch


you didn't state how many hours are on the unit, but I'm guessing close to 3,000 hours, that is when most brands have LCD panel failures, due to the heat over time the coating on the lcd panels burns off, the panels start to burn up, and it gets worse with time, and you notice it more when you put a fresh bright lamp in. if it is low hours then you could have a bad lamp, that casts a bad tint, but it sounds like fried LcD panels, a sure way to tell, is put up a white back-ground screen and see if you see discolored "BLOB" in the center of the screen.
keeping the filters clean, and the projector cool is the best way to prevent this.

ERROR MESSAGE: "Checksum error."


The Checksum error usually indicates a data transmission issue. This may be due to a loose connection, bad wiring, electrical interference (cross-talk), a physical problem with the device itself, or a conflict caused by another software program. * Make sure that the cable attaching the camera to the computer is secure at both ends. * Close down all of the computer's other applications before attempting to download. 1. Press the CTRL, ALT and DELETE keys simultaneously. This will bring up the Close Program Window. 2. Highlight the program that you want to close and select END TASK. The Close Program window closes only one program at a time, so you will have to repeat these steps for each program that you want to close. NOTE: The SYSTRAY and EXPLORER programs should be allowed to run. Do not select End Task for these programs. You will also want to leave any necessary programs running, such as those controlling a wireless mouse or keyboard.
