Updating linux lenovo
It may or may not work for you, even if the BIOS Update (Bootable CD) iso-image has the same structure.It is not clear what is the root of the problem, but in some cases PC-DOS, used by Lenovo, hangs when booted via cat /etc/grub.d/20_bios_update #!Note: On UEFI systems, the procedure below does not work, since memdisk is not UEFI compatible.In this case, just 'dd if=of=/dev/sdb' the extracted image (e.g., bios.img) to an usb drive (e.g., sdb) and try booting from it.A quick look at the BIOS Update (Bootable CD) iso-image shows that its , i.e. Therefore non of the methods discussed in BIOS_Upgrade/X_Series would work.
Quick check shows that in some cases it has the same structure as above, i.e. However, common sense tells that it is not a good idea to read the firmware from the same very harddrive whose firmware we are updating.Use the following command to update the archive:sudo update-initramfs -u The update-initramfs program reads all the files in /etc/modprobe.d and all the module names in /etc/modules while compressing the image.You must restart your computer to load the modules.For example, blacklist the open-source wl wireless module by adding the following line to the file:blacklist wl To find out which modules you need to blacklist, you must search the Ubuntu website for the hardware component you're trying to get working (link in Resources).Open the file /etc/modules in Gedit to add the names of modules you want to load at startup.Be careful not to change # the 'exec tail' line above.menuentry "BIOS Update" Disclaimer : it is certainly possible to the grub "memdisk.mod" but documentation was scarce and this way is working fine.Place one module name per line as in the following example:snd-usb-audio b43legacy fuse This step is only necessary if Ubuntu doesn't automatically detect your hardware at startup.Update initramfs to add the changes to the startup archive.If you have an optical drive of some kind (internal, or built into the docking station, or an external USB drive) you can burn the iso-image and proceed with the BIOS update.In case if you don't have any optical drive things get a little tricky.
