[Lalitha V.N.]

Hi......

Thanks for your reply........

We have tried like this,we have copied original BIOS(PM49FL004) content in
the filename feb6 and tried to flash on

SST49LF004B flashrom chip  and then we followed this steps .....

 root at turtle10 ~]# /usr/sbin/flashrom -E

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).

 [root at turtle10 ~]# /usr/sbin/flashrom -w feb6

Calibrating delay loop... OK.

No LinuxBIOS table found.

Found chipset "VT8237", enabling flash write... OK.

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

Verifying flash... FAILED!

Still  we are unable to flash , please guide us  which procedure should
follow and is it necessary

for us to change the flashrom chip? otherwise is it required to change the
code in flashrom utility....?

if it is require please guide where we need to change.. such that flash can
happen..

Lalitha.
