Hello all ............
we are working on the coreboot project .....
[root@turtle9 flashrom]# flashrom
Calibrating delay loop... OK.
No LinuxBIOS table found.
Found chipset "VT8237", enabling flash write... OK.
generic_spi_command called, but no SPI chipset detected
Pm49FL004 found at physical address 0xfff80000.
Flash part is Pm49FL004 (512 KB).
No operations were specified.
Reading the original Bios content in to the file jan14:
[root@turtle9 flashrom]# flashrom -r jan14
Calibrating delay loop... OK.
No LinuxBIOS table found.
Found chipset "VT8237", enabling flash write... OK.
generic_spi_command called, but no SPI chipset detected
Pm49FL004 found at physical address 0xfff80000.
Flash part is Pm49FL004 (512 KB).
Reading Flash...done
[root@turtle9 flashrom]# flashrom -v jan14
Calibrating delay loop... OK.
No LinuxBIOS table found.
Found chipset "VT8237", enabling flash write... OK.
generic_spi_command called, but no SPI chipset detected
Pm49FL004 found at physical address 0xfff80000.
Flash part is Pm49FL004 (512 KB).
Flash image seems to be a legacy BIOS. Disabling checks.
Verifying flash... VERIFIED.
***Then we removed the original Bios chip and inserted the new flashrom SST49LF004B and tried to flash(write)
the content present in the filename jan14 ,but finally we got the result as bellow ........
Writing on to the new Bios chip (SST49LF004B):
[root@turtle9 flashrom]# flashrom -w jan14
Calibrating delay loop... OK.
No LinuxBIOS table found.
Found chipset "VT8237", enabling flash write... OK.
generic_spi_command called, but no SPI chipset detected
SST49LF004A/B found at physical address 0xfff80000.
Flash part is SST49LF004A/B (512 KB).
Flash image seems to be a legacy BIOS. Disabling checks.
Programming page: 0007 at address: 0x00070000
Then we varified .....
Calibrating delay loop... ok No LinuxBIOS table found. Found chipset "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 - FAILEDSo we tried to change the flashrom utility code..so first we downloaded coreboot code
