Please try this:<br><br>flashrom -E<br>dd if=/dev/zero of=zero.bin bs=1024 count=512<br>flashrom -v zero.bin<br><br>This should tell if the erase or write is where the problem is. Probably the write, but better to know for sure. Also, please do a "reply all" to your mailing's last response on the list, it helps to keep threads organized.<br>

Hi......<br><br>Thanks for your reply........<br><br>We have tried like this,we have copied original BIOS(PM49FL004) content in the filename feb6 and tried to flash on <br><br>SST49LF004B flashrom chip and then we followed this steps .....<br>

<br>if it is require please guide where we need to change.. such that flash can happen.. <br><br><br>with regards,<br><font color="#888888">Lalitha.<br><br>
