Asus P8P67 LE works, successfully wrote and verified - flashrom

9 May 2013


      Hello, I checked your wiki matrix, and I'm not sure i quite understand
where it says "NO (42)" what exactly means.
I have this motherboard, which is a B2. there is a B3 next to it in
your hardware table with a green "OK" (P8P67 PRO). I went ahead and
tried flashing anyway and it worked!, It could write and verify back
an old bios (1104) downloaded from Asus page.
This board was nearly bricked by the writing of a B3 bios which made
all sort of trouble to it, after several attempts (wouldn't post) i
managed to boot linux and went with flashrom.
Note 42 has this written: "Probing works (Winbond W25Q32, 4096 kB,
SPI), but parts of the flash are problematic: descriptor is r/o
(conforming to ICH reqs), ME region is locked." But this is wrong,
flashrom identified chip MX25L3205 like the other 2 previous models. I
have no idea what this ME and ICH business is to deserve a red NO, but
it worked with mine.
Asus page happily mentions "Pre-B3 revision motherboard users can also
download and use the new B3 revision BIOS, drivers and utilities."

That is absolutely wrong!, Pre B3 users can't use any B3 BIOS image!.
In my case, the bios got all sensor values wrong, and it wanted to
shutdown as it thought the processor was over/under temp, voltage etc,
i managed to turn off all power setting things i could to be able to
post, and the bios would often freeze requiring moving the clear
jumper before even wanting to turn the power on again many times.
I also learned something about Asus: while their BIOS EZ Flash tool
happily allows upgrading to this dangerous B3 bios in a B2 board, it
won't let you flash back to the older working version, genius move...
I used flashrom 0.9.5.2+r1517-1 from the Ubuntu repository.
flashrom v0.9.5.2-r1517 on Linux 3.5.0-28-generic (x86_64), built with
libpci 3.1.8, GCC 4.6.3, little endian
flashrom is free software, get the source code at http://www.flashrom.org
Calibrating delay loop... OK.
Found chipset "Intel P67". Enabling flash write... OK.
Found Macronix flash chip "MX25L3205" (4096 kB, SPI) at physical
address 0xffc00000.
