I really need to write a short tutorial on how to do password recovery with flashrom if you can still boot the machine (i.e. only a BIOS setting screen password) or if you can open the machine and access the flash chip.

[PATCH] Compile fixes, update README
by Carl-Daniel Hailfinger 08 Oct '10

08 Oct '10

I wanted to tag 0.9.3, but then I noticed that compilation was broken in a few cases, and the README had insufficient information. Fix that. In detail: CONFIG_BITBANG_SPI was not selected if CONFIG_NICINTEL_SPI was on by default. Wiki output was missing all flash chips if CONFIG_INTERNAL was not selected. ft2232_spi used possibly negative indices in the toupper() function/array. Software requirements on non-Linux/FreeBSD/OpenBSD operating systems were missing. Non-x86 compilation does not work with the default programmer set, so list the make parameters which result in a working build.

[PATCH] Note to add the board/device name to the subject when contacting the ML.
by Paul Menzel 08 Oct '10

08 Oct '10

A lot of messages sent to flashrom(a)flashrom.org just have »flashrom -V« as the subject rendering it in my opinion unusable. Adding the board/device name to the subject would help a lot when skimming over the messages by the subject line or searching the messages just using the subject line. • I did not add that note to outputs saying to report a bug to the mailing list. • I do not know if the subject line can be created automatically in those message, so users just have to copy and paste them. • I am not a native speaker, so I do not know if using plain »subject« instead of »subject line« would be enough and if the propositions I used are correct.

Update the man page to have correct info for the upcoming release. If you know of any features which are not mentioned in the man page, please tell me. If you know any major contributors who were forgotten, please tell me. If you find any bugs, please tell me. Should we mention all contributors with more than one patch? Should we restrict the author list to those who have substantial amounts of code in flashrom? Do we have to ask people if adding their email address to the manpage is OK?

Hi flashrom devs, flashrom suggested to send you a report if PROBE READ EREASE & WRITE work. so here it is Board: http://www.pcengines.ch/alix1d.htm $ sudo flashrom -w ALIX0.BIN flashrom v0.9.2-runknown on Linux 2.6.31-ARCH (i586), built with libpci 3.1.4, GCC 4.4.1, little endian flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop... OK. No coreboot table found. Found chipset "AMD CS5536", enabling flash write... OK. WARNING: unexpected second chipset match: "AMD CS5536" ignoring, please report lspci and board URL to flashrom(a)flashrom.org! This chipset supports the following protocols: Non-SPI. Found chip "Winbond W39V040(F)C" (512 KB, LPC) at physical address 0xfff80000. === This flash part has status UNTESTED for operations: PROBE READ ERASE WRITE The test status of this chip may have been updated in the latest development version of flashrom. If you are running the latest development version, please email a report to flashrom(a)flashrom.org if any of the above operations work correctly for you with this flash part. Please include the flashrom output with the additional -V option for all operations you tested (-V, -Vr, -Vw, -VE), and mention which mainboard or programmer you tested. Thanks for your help! === Flash image seems to be a legacy BIOS. Disabling checks. Writing flash chip... Erasing flash chip... SUCCESS. Programming page: DONE!ss: 0x0007f000 COMPLETE. Verifying flash... VERIFIED. see the attached files for the output of flashrom -V and flashrom -Vr regards, roughl
