Try Peters suggestion of reading the flash after an erase and see what is there.<br>
<br>
If it is erased, read back after you have tried to write and compare.<br>
<br>
See what is or is not happening.<br>

Hi all..<br>
I have worked with PM49fl00x.diff patch ,its worked fine<br>
and i got the output as below<br>
<br>
The PM49fl00x can work in LPC and FWH modes. Do you know which<br>
mode is being used?<br>
What mainboard did you test this in?<br>
<br>
Now i am working on SST49LF004B 33-4C-NHE<br>
0710022-CA with the<br>
motherboard K8Upgrade-VM800<br>
The flashrom detect flash device on this<br>
board, But the erasing and writting operation is not happening<br>
properly<br>
hier flashrom output : <br>
Is this the board by ASRock?<br>
<br>
