Hi, I have fooled myself. The proc file indeed just gives some status output. And I didn't open it in a text editor...
On http://www.pixelbeat.org/docs/bios/ it is written: "Note you may need to sudo modprobe nvram to make this device available on your linux system, and you can confirm the driver is loaded by the presence of the /proc/driver/nvram file which represents some legacy CMOS parameters." ... "one can copy the settings with the dd if=/dev/nvram of=nvram.saved command. If your other machines have exactly the same BIOS settings then it's trivial to copy them to the other machines with the dd of=/dev/nvram if=nvram.saved command." To read out the nvram just do this with the /dev/nvram file (not /proc/driver/nvram !): michael@ideapad:~/nvram$ sudo modprobe nvram michael@ideapad:~/nvram$ sudo cat /dev/nvram > nvram michael@ideapad:~/nvram$ ll total 4 -rw-r--r-- 1 michael michael 114 2012-10-16 20:47 nvram michael@ideapad:~/nvram$ less nvram "nvram" may be a binary file. See it anyway? michael@ideapad:~/nvram$ hexdump -C nvram 00000000 00 00 00 42 00 a2 03 79 02 00 fc 00 00 74 24 60 |...B...y.....t$`| 00000010 6e 23 20 42 98 47 12 20 30 04 c5 91 7e f9 03 e0 |n# B.G. 0...~...| 00000020 09 3e 00 fc 20 cc cf f9 01 00 00 06 ea e3 30 00 |.>.. .........0.| 00000030 00 60 3b f9 05 94 28 80 ca 06 0a 00 00 00 00 00 |.`;...(.........| 00000040 40 db 16 00 78 0a 92 ff ff 1f b0 00 07 f4 01 06 |@...x...........| 00000050 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 00000060 00 00 db 80 10 00 00 00 00 00 00 00 00 00 00 00 |................| * 00000070 Looks better. ** Attachment removed: "nvram image of my laptop (BIOS version 2ACN21WW) after WLAN has been enabled using the workaround" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/577114/+attachment/3207111/+files/nvram-2ACN21WW-2012-06-28-wlan-working-after-workaround.nvram -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/577114 Title: Wireless and Bluetooth switch does not work correctly on lenovo ideapad s10-3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/577114/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
