This is the non-verbose version? I had trouble parsing that message flood on the first attempt. May I suggest an alternative wording? WARNING: Flash Descriptor region is not fully accessible. WARNING: Management Engine region is not fully accessible. WARNING: PR0: 0x007d0000-0x01ffffff is read-only. Please send a verbose log to flashrom(a)flashrom.org if this board is not listed on http://flashrom.org/Supported_hardware#Supported_mainboards yet. Writes have been disabled. You can force writing with the ich_ignore_locks programmer option, but it will most likely brick your mainboard. The idea of my wording is to postpone the explanatory message until all "not accessible"/"read-only" messages have been printed. The complaint about Intel belongs to the man page or to intel_mysteries.txt (if you choose the latter, just mention intel_mysteries.txt at the relevant location in the man page). For the override case, just print the message above and additionally "You have been warned. We will not support you if write/erase bricks your mainboard. Proceeding anyway because user specified ich_ignore_locks." or something similar. > Signed-off-by: Stefan Tauner <stefan.tauner(a)student.tuwien.ac.at> > --- > flashrom.8 | 15 ++++++++++ > ichspi.c | 90 +++++++++++++++++++++++++++++++++++++++++++++++------------ > 2 files changed, 86 insertions(+), 19 deletions(-) > > diff --git a/flashrom.8 b/flashrom.8 > index 2f23cb8..0ca4fdb 100644 > --- a/flashrom.8 > +++ b/flashrom.8 > @@ -315,6 +315,21 @@ important opcodes are inaccessible due to lockdown; or if more than one flash > chip is attached).

Re: [flashrom] [PATCH] Warn of one-time programmable (OTP) memory
by Carl-Daniel Hailfinger 16 Feb '12

16 Feb '12

Hi Stefan, I have waited very long to comment on this patch, but I simply don't have a good answer for it. I do think that OTP/security memory is outside the scope of flashrom because it behaves totally different (and testing could easily kill a dozen chips during inital implementation, and a few chips each time someone wants to retest). Now if something is outside the scope of flashrom, should flashrom care at all? Some flash chips have GPI pins (GPIO without output) and those are readable with commands very similar to those used by flashrom. Should we tell the user about that feature as well? We had such requests in the past, and I was not really happy about them. Am 14.08.2011 05:36 schrieb Stefan Tauner: > Some flash chips contain OTP memory that we cannot read or write (yet).

I've seen datasheets for flash chips with the following features: - OTP memory, fully readable, fully writable once in one block (no partial writes) - OTP memory, fully readable, fully writable once per byte (partial writes work just fine) - OTP memory, fully readable, fully writable once per 2^n-byte block - OTP memory, fully readable, only half of it writable, the other half is programmed at the factory - OTP memory, fully readable, completely pre-written at the factory (so it's rather ROM than OTP) - Hidden OTP memory which can only be read if you know the correct security ID which is part of the OTP - (The complete flash chip behaves like OTP (well, like ROM) once a specific write-once status register is set)... not relevant here And then you have the problem that multiple chip generations often share the same device ID, so probing can't differentiate between a chip with OTP and one without unless you're extremely lucky. Do we want FEATURE_OTP and FEATURE_MAYBE_OTP? Do we warn if a chip has a readonly serial number? That means the chip can't be cloned. People who care about OTP for clonability reasons probably care about other readonly contents as well. OTOH, other people who don't use the OTP at all (for them, OTP is just an accidental feature of a cheap flash chip) don't want to be bothered by yet another line of output from flashrom which has no relevancy for them. > The manpage is extended to describe the backgrounds a bit.

To be honest, trac is something I never got along with. Even if I'm logged in there is no way for me to read the email address of the person who opened the bug, so communication is pretty difficult. I'm all for checking all old trac tickets, closing what can be closed, and moving all other tickets in some way or another to the mailing list. However, we should mention that it's OK to report bugs via IRC as well as long as the reporter mentions a way to contact hi/her (i.e. email address). Removing the trac reference and adding the IRC reference should be a separate patch, though, which is Acked-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006(a)gmx.net> One comment about the man page formatting: This part of the patch may conflict with the other man page formatting patch you sent.

[commit] r1493 - trunk
by repository service 16 Feb '12

16 Feb '12

Author: stefanct Date: Thu Feb 16 00:40:23 2012 New Revision: 1493 URL: http://flashrom.org/trac/flashrom/changeset/1493 Log: Warn of one-time programmable (OTP) memory Some flash chips contain OTP memory that we cannot read or write (yet). This prohibits us from cloning them, hence warn the user if we detect it. Not all variations of the tagged chips contain OTP memory. They are often only enabled on request or have there own ordering numbers. There is usually no way to distinguish them. Because this is a supposedly seldomly used feature the warning is shown in with dbg verbosity. The manpage is extended to describe the backgrounds a bit. This patch is based on the idea and code of Daniel Lenski.

Re: [flashrom] successful BIOS flash report

Hello Stefan. Thanks for your reply. Much appreciated. As requested, please find below the output of actual writing of the BIOS and below that the output of "flashrom -V". The link to the mainboard: http://www.asus.com/Motherboards/Intel_Socket_775/P5KV/ The link to the mainboard manual: http://dlcdnet.asus.com/pub/ASUS/mb/socket775/P5K-V/e3269_p5k-v_manual.zip I don't know the exact revision of the board. The board was purchased in Oct 2007. Kind regards.

Op 15-2-2012 16:23, Stefan Tauner schreef: > Also, rephrase the documention related to laptops completely to make it > less redundant and more informative. > Document the laptop=this_is_not_a_laptop internal programmer parameter Whatever happened to flashrom's semi-dependency on DMIDECODE? I thought flashrom implemented its own dmi-calls since 0.9.4, but trying Idwer's DOS-port (rev1452) and not having DMIDECOD.EXE (yep, 8.3 naming, sorry) all I end up with in VMware/FreeDOS is a "hey can't identify anything, so this must be a laptop..if not, please override". Overriding still produces the same 'please override' output followed by a message that you're overriding, and continues. Ofcourse no single emulation platform seems to have a flashrom anyway, so stuff happily aborts. I guess flashrom could at least continue to try reading without needing an override. Erasing and writing ofcourse do require overrides if anything is uncertain in advance.
