Hi..
We are having two BIOS i.e, PM49FL004( motherboard's BIOS) and empty flashrom
SST49LF004B ..
We are trying to flash the content of PM49FL004 to SST49LF004B flashrom
according to your suggestion we have done ..we are getting output as bellow..
[root@localhost ~]# flashrom -E
Calibrating delay loop... OK.
No coreboot table found.
Found chipset "VIA VT8237", enabling flash write... OK.
SST49LF004A/B found at physical address 0xfff80000.
Flash part is SST49LF004A/B (512 KB).

Flash image seems to be a legacy BIOS. Disabling checks.

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

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