assistance with updating my bios

[Elia Yehuda]

Hi all,

I'm trying to play with coreboot to flash my bios on my PC, with no success.
here are the computer hardware information followed by the commands I'm
trying to execute.

<INFO BEGIN>

$ flashrom -f -r -c M50FW016 mydump
Calibrating delay loop... OK.
No coreboot table found.
Found chipset "Intel ICH", enabling flash write... OK.
No EEPROM/flash device found.
Force read (-f -r -c) requested, forcing chip probe success:
Found chip "ST M50FW016" (2048 KB) at physical address 0xffe00000.
Force reading flash...done

$ flashrom -f -w -c M50FW016 mydump
Calibrating delay loop... OK.
No coreboot table found.
Found chipset "Intel ICH", enabling flash write... OK.
No EEPROM/flash device found.

I'd appreciate any assistance as all this flashing stuff is new to me.
Basically what i'm trying to accomplish is having my linux system running as
the payload, but i'm stuck with even re-writing the same bios-dump i've just
read from the bios... I'll post any further information required to diagnose
this further.

thanks in advance,
Elia Yehuda.

It is a bad sign if you had to force the chip type for the read operation.

Force write can't work because the strategy for access is unknown.

Can you run
flashrom -V
and report the results to this list?

We may need to change the chipset/board enable sequence for your board.

Can you try the following flashrom patch? It should find the chip and
allow you to read it. Erase and write will NOT work and may crash.

Attached if gmail mangles the inline patch.

Add support for the ST M50FW002 chip to flashrom. Identification only,
erase/write are not implemented.
