jetway PA78VM5 spi flashing

[Qing Pei Wang]

hi all,
    Recently i found that the mainboard which i used(Jetway PA78VM-H-LF) is
not stable, most of the spi flashing caused data error.
the data writing is ok, but the bios data does not as the same  as the
original. the SPI FLASH is Winbond W25X80A
In the other hand, the board can not boot correctly, i am wondering if it's
because of the CPU. Olsen, have you ever met this problem?

Is the flash chip flashed onboard using flashrom, or externally by
another system?

If onboard, what chip is SPI bus master on the board? Is it the SB700
or some LPC->SPI bridge?

Same problem both with SF100 and onboard flashing?

That could mean that the flash chip is bad.

I tried another board, it's ok...
it may because of the flashchip.
