[flashrom] A8M2N-LA flash fail fail

[Márton Miklós]

Hello all,

I have just tried to flash my BIOS using the flashrom, and I have ran 
into the following situation:

lucifer at lucifer-desktop:~/Letöltések/flashrom-0.9.4$ sudo ./flashrom -w 
/tmp/sp35111/3.10
flashrom v0.9.4-r1395 on Linux 2.6.35-28-generic (i686), built with 
libpci 3.1.7, GCC 4.4.5, little endian
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Found chipset "NVIDIA MCP51".
This chipset is marked as untested. If you are using an up-to-date version
of flashrom please email a report to flashrom at flashrom.org including a
verbose (-V) log. Thank you!
Enabling flash write... OK.
This chipset supports the following protocols: Non-SPI.
Found PMC flash chip "Pm49FL004" (512 kB, LPC, FWH) at physical address 
0xfff80000.
Flash image seems to be a legacy BIOS. Disabling coreboot-related checks.
Reading old flash chip contents... done.
Erasing and writing flash chip... ERASE FAILED at 0x00000000! 
Expected=0xff, Read=0x23, failed byte count from 0x00000000-0x00000fff: 
0xfec
ERASE FAILED!
Reading current flash chip contents... done. ERASE FAILED at 0x00000000! 
Expected=0xff, Read=0x23, failed byte count from 0x00000000-0x0000ffff: 
0xfef9

FAILED!
Uh oh. Erase/write failed. Checking if anything changed.
Good. It seems nothing was changed.
Writing to the flash chip apparently didn't do anything.
This means we have to add special support for your board, programmer or 
flash chip.
Please report this on IRC at irc.freenode.net (channel #flashrom) or
mail flashrom at flashrom.org!

You may now reboot or simply leave the machine running.

I have tried the latest revision (1402) but it did not works too.
Let me know if I should provide any additional information.
