This will generate an SMI when you attempt to set bit 0. There will be SMM code that will reset bit 0 if you have not performed the correct handshake beforehand. This is a protection mechanism to prevent unauthorised modification of the BIOS. Andrew

Fwd: BIOS Write Enable bit problem.
by Rich Futyma 09 Feb '13

09 Feb '13

Guys, Does anyone know why bit 0 in the BIOS Control register cannot be set using Intel® X79 Express Chipset. This is what I get when running: flashrom -r /tmp/bios.rom -p internal or flashrom -w xx.rom -p internal *Warning: Setting Bios Control at 0xdc from 0x2a to 0x0b on X79 failed.* *New value is 0x2a.* The read command completes and I get the correct data, but subsequently when I try to erase and program my flash (./flashrom -w xx.rom -p internal:ich_spi_force=yes) I get FCERR (on the first sector erase) which implies that the BIOS is write protected.

If it was really deleted/erased or a bad image was flashed, then you have to reprogram the chip either with a flash chip programmer. One way is to find a motherboard where the chip fits and reprogram it there by hot swapping it. If that is not possible ask around in your local hacker community or find a shop which does it. > Please, I will be looking forward for your comments. I wish you good luck with recovery! You should also join the #flashrom IRC channel on irc.freenode.net. Thanks, Paul [1] http://flashrom.org/Supported_hardware

The above command, 'flashrom -r', will not erase a flash chip. Have your friend either power cycle his machine or remove the mainboard battery (CMOS reset) with mains disconnected. Given the fact that the parameter '-p internal' was not used, he was using an old version of flashrom, version 0.9.3 or older. > > Please, I will be looking forward for your comments. > Thanks in advance. > > H. > > _______________________________________________ > flashrom mailing list > flashrom(a)flashrom.org > http://www.flashrom.org/mailman/listinfo/flashrom

Hello guys, I have subscribed to this mailing list looking for some help about the use of the flashrom tool. The problem is this: A friend of mine who has just started using Linux, was testing some tools and not reading carefully their corresponding manuals, he executed this command: flashrom -r and this seems to have erased the BIOS of his PC. This is my guess because he just told me by phone that not even the video signal was working. His motherboard is an ASUS P5GC. Is it possible to recover the BIOS back to the previous state?? Please, I will be looking forward for your comments. Thanks in advance. H.

That's one of the other things my patches fix :) The image you supply with -v/-r/-w is always used to present a mapping of the whole chip. The layout information is only used to select the address range inside that mapping. So for vanilla flashrom you have to create an 8MB file and fill the first 4MB with the content you want and continue as you have done. With my patches one can add an image name to any -i parameter (e.g. -i main:main.img) which is then mapped to the corresponding offset. IIRC one has still to supply a whole image with the correct size, but if the needed ranges are also present as "-i images" then it would not be used at all. Similar for the read operations: it would create a whole image with a lot of 0xFFs outside the selected regions and smaller/exact files for the "-i images". Maybe I have some time at the weekend to integrate the patches. I think there is consensus that we want them in and they have been tested by a number of people, so i think it should not break too much :) -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

It does so to be able to skip blocks that have the wanted content already and to be able to tell you if anything has changed in the case of an error (not so important on external programmes, but very interesting for people writing their live BIOSes and seeing errors). Usually reading does take way less time than erasing/writing or might even speed up the whole process. ATM there is no way to disable this behavior but we plan to do so and IIRC a part of the mentioned patch set is a first step into that direction. > The other problems are: > - That most of flashrom seems to be limited to 2^24 address bits. > (this is relatively easy to fix) We will see about that :) We are of course aware that this is needed quite soon.

The flag is there to fix exactly this :) See also http://patchwork.coreboot.org/patch/3757/ Not many chips need this and so we never moved into this direction... do you really need it? > I've also found that flashrom doesn't always do what I expect, and I'm not > sure if this is > by design or not. for instance, if I want to erase my entire flash chip, > it ends up calling > the sector erase on each sector, not by doing a chip-erase? Are these > types of things > written down anywhere? We try to erase the smallest possible blocks first (in order of the eraser array of the chip definition(s) in flashchips.c. This potentially allows to skip writing of block as explained above. It is of course rather useless for the -E/--erase operation, but the code is shared and no one complained yet IIRC (or sent a patch). Most of these details are not documented I think, but some are (in the manpage). Patches for the manpage are welcomed. Everyone is invited to edit the wiki too :) -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

The SST25VF040B was added before the new naming scheme was implemented.

That chips has a identical chip ID = 0x2537. if if will be MX25.64...(F) that i think it's don't readable. -- With best regards Nikolay Nikolaev С Уважением Николаев Николай
