Are you absolutely certain that the chip is an SST49LF004? You aren't
using a BIOS Savior with a switch in the wrong position? I know this
sounds a little odd, but here's the deal: the flash chip vendor and
model that flashrom is reporting aren't anywhere near what they should
be for that chip. So, either you have a different chip, or else the
board is somehow masking the chip ID, and reporting a false one. It
could be that the board is somehow disabling access to its own flash
chip, and instead copying the BIOS contents to ram (although the more I
think about it, the more far-fetched and maybe even impossible that
sounds). Do you have a floppy drive that you can use uniflash to try to
flash, or at least identify, this chip?

Yes I tried it on ASRock motherboard and it is detecting. I am not using BIOS Savior,  instead I am removing the Pm49FL004 chip and inserting the SST49LF004A/B chip in the Bios socket and after that using flashrom utility to do further operations.
