Flashrom programm allow to save existing BIOS, but don't want to write new one.
The original programm behavior, AFUDOS.EXE, exactly the same, it get the file from bios,
but don't want to write to bios.

Obtained bios files exactly the same, independently, wheter one was obtained with the help of flashrom or AFUDOS.EXE

And both slightly differs with the BIOS downloaded from the ASUS site with the same number, 804.

flashrom -V
dmidecode -t bios
flashrom  --programmer internal -w M2NX1004.ROM

Thank you, best regards

Calibrating delay loop... OK.
Found chipset "NVIDIA MCP61". Enabling flash write... This chipset is not really supported yet. Guesswork...
Please send the output of "flashrom -V" to flashrom at flashrom.org with
your board name: flashrom -V as the subject to help us finish support for your
chipset. Thanks.
OK.
Found SST flash chip "SST49LF040B" (512 kB, LPC) 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 0x0000000c! Expected=0xff, Read=0x08, failed byte count from 0x00000000-0x00000fff: 0xf92
ERASE FAILED!
Reading current flash chip contents... done. ERASE FAILED at 0x0000000c! Expected=0xff, Read=0x08, failed byte count from 0x00000000-0x0000ffff: 0xfe27
ERASE FAILED!
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!
