Thank you for the URL.
coreboot is not even mentioned. Searching for »source« or »closed« did
not turn anything up either, so I guess having access to the source code
is not mentioned as an essential way of protection.
I guess you guys (adding flashrom to CC) will have more comments. Will
you post them in your answers? Maybe we can contact the authors of this
this is admittedly a little off-topic but I with all the BIOS-experts here,
I hope there might be somebody who knows about this:
Is there any way to modify the daylight savings time bit (see
of the "realtime" clock of a i386 machine running linux?
"nvramtool" won't touch the 1st 14 bytes of the CMOS. I tried changing
"hwclock" but this uses the kernel rtc driver which obviously also does
not allow to change the DST setting.
(This is of course useless for Linux - I need it in connection with
problems involving some well-known system from Redmond ...)
Sorry if this has been gone through before but...
I've been put off by the various problems I've read about updating the BIOS on
my XW9400 motherboard to support quad core processors. There seem to be various
problems ( mac addresses going awol ) and things that need to be done (
connecting jumpers etc. ) which have made me think it isn't worth it.
But - I've decided I want to give it a go...
My understanding is that I need to short out a jumper on the board - I think I
know which points I have to bridge - but does anyone have a picture - just to
make me feel sure I'm not going to blow the entire board up :-/
I have the latest version of flashrom - the process I think I need to go through
is ... I've used
sudo flashrom -r biosbackup.rom -m hp:xw9400
to copy the current image.
I'm assuming I have to use
sudo flashrom -m hp:xw9400 -w 7D6_0403.bin
to flash it with the 4.03 image off the HP web site. I'm assuming that with the
write enable, this will update the boot block - but will this also remove the
MAC addresses - or is that some other problem people have had?
Thanks for any help.
I didnt want to mix this randomness into my patch mail, so I'm sending two.
I set up a simple web page for serving all the files related to this little
project of mine: http://urjaman.dyndns.info/usbavrprog/ .
You might be able to see that there is a reason for why I dont normally do
web design stuff ;), but it gets this stuff out.
(FYI: This webserver is going to be down starting 2011/05/21, hopefully
ending before end of 2011/06.)
Also, I've written code for it and for flashrom to support SPI protocol over
serprog, so I will be sending a patch to flashrom next.

Please post the full log (possibly with --verbose)
Also, does the image in flash match what you previously read from the
chip? In that case it's most likely that the flash is write protected
I am a Software Engineer from Raytheon Anschütz Germany and wanted to use
flashrom to update the bios of our embedded bord form emerson.
Unfortuneately s.th. must have gone wrong. First write of the bios was
fine but after reboot I got a crisis report that the two flash banks are
corrupt. I could boot from thumb drive anyway and wanted to write the
backup copy but got the following error message:
Erase failed at 0x00000010! Expected=0xff, Read=0x5a, failed byte count
from 0x00000000 - 0x0000ffff: 0xd092.
