Re: [flashrom] [coreboot] BIOS Protection Guidelines from NIST

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 article too. Thanks, Paul

Set DST bit in RTC clock?
by Peter Daum 17 May '11

17 May '11

Hi, 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 http://www.plasma-online.de/textual/download/misc/cmos_registers.html) 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 ...) Any ideas? Regards, Peter

XW9400 upgrade
by Nigel R 16 May '11

16 May '11

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. Nigel

My USB+AVR-based flasher (w/ serprog protocol fw) gets spi support and a little webpage
by Urja Rannikko 15 May '11

15 May '11

Hi, 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. -- Urja Rannikko aka urjaman

In that case it's most likely that the flash is write protected Stefan

Erase faild
by Marco Runge 12 May '11

Hi, 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. We are using the following board: http://www.emersonnetworkpower.com/en-US/Products/EmbeddedComputing/Compact… Chipset: Intel Ibex Peak Found chipset: Atmel AT25DF641 8192Kb SPI at 0xff800000 I hope you can help Best regards Marco Runge Marco Runge Software Engineer EDA BAD Raytheon Anschuetz GmbH +49 431 3019 646 office +49 431 3019 291 fax Marco_Runge(a)raykiel.com Zeyestrasse 16 - 24 D-24106 Kiel Germany www.raytheon-anschuetz.com Raytheon Anschuetz GmbH Sitz der Gesellschaft: Kiel Registergericht: Amtsgericht Kiel HRB 4086 Geschaeftsfuehrer: Dr. Lueder Hogrefe Vorsitzender des Aufsichtsrats: Patrick K.
