BIOS/Flash Setting & Programming

  Programming BIOS chips with this enhanced programmer is easy, as long as the correct chip type ID and right jumper are selected. Here is an example to show you how to program a N82802AB from Intel845 mother board(3.3V):

Note: when programming N82802AB chips, only 12V programming voltage is needed. So, to prevent the chips from being damaged by hi-voltage, please enable the Safety Protection Jumper.

1, select chip type and software setting

 now you can see the following settings:

 DIP position: OFF,ON,ON,OFF,ON,ON,OFF,ON,OFF,ON,OFF,ON

  Relevant parameters are listed below the Chip  Select  Button. Normaly, these parameters do not need to be adjusted, just use the default value.
Size&checksum:  shows chip's capacity and data buffer's checksum.
Shift&pattem adress: shows chip's address line to be used and highest address bit.
tWP/WC: shows programming  pulse width and delay time.

2. check chip's position

  For BIOS chip,such as N82802AB, the program will prompt the user to acquire a FWH/LPC adaptor. This enhanced Willem programmer has a built-in FWH/LPC socket, thus no extra adapter is needed.

Please make sure the pin one position on the FWH/LPC adapter.

 

3, read from chip

After selection of the chip, we can click the "Read" button. All data will be read into the buffer.

4, Programming

  Insert the chip, then click "Open file" to load your data file into the buffer of the software. Then click "Programm Chip" button.  Note,  some chips  need to be erased before writing.
 .

5, copy a chip:
  1), Select the chip type and then put in the original chip. 

  2), "read" the data into buffer.

   3), Put in the target chip and then click "Programm Chip".

Note: the chip may be damaged if wrong chip type selected or chip inserted in wrong direction in socket.
 The following parameter is for advanced user only.

R/C delay time: programming pulse delay. If your computer is too fast, you may need to increase the delay.

Skip Write 0xFF: Enable this setting will skip the 0xFF when programming.
Fast Programming: For a fast programming mode if it is enabled.
Printer Port:  LPT1(0X378), printer port selected.
Offset: setting programming start offset affress.
Check Type: You can select the way to check  either 32 bit CRC or 16 bit add.


Note:

1, some chips need to be erased before being programmed. Such as SST39SF020.

2  Always put the chip in the programmer as the last step.

3, Do not interrupt the programming procedure. Press the "Stop" button if needed.
