Update bios from Linux on HP Elitebook 840 G3

gistfile1.txt

!!! WARNING Selecting wrong /dev/sdX might wipe your main harddrive !!!
!!! These are only notes, not a step by step !!!

Download BIOS from HP's page, find your correct bios files via serialnumber
# sudo dmidecode |grep -A 4 "HP EliteBook"

Download the service pack spXXXXX.exe

# apt-get install wine-stable
# wine spXXXXX.exe

Follow the installer instructions, pretty much the : next next accept next ok dance...

Grab an old USB stick you can wipe, insert it and find out what /dev/sdbXXX it attaches as. (dmesg is your friend)


!! WARNINGS: THIS WILL ERASE sdX, BE SURE ITS THE USB STICK !!

# sudo dd if=/dev/zero of=/dev/sdX bs=1M count=10
# sudo cfdisk /dev/sdX
Create a dos partition table and one partition, W95 Fat32 LBA.
Write changes to disk and exit cfdisk

# sudo mkfs.vfat -n HP_TOOLS /dev/sdX1
# sudo mount /dev/sdX1 /mnt
# cd /mnt && mkdir -p Hewlett-Packard/BIOS/New

BIOS filename and spXXXXX may vary...
# sudo cp /home/$YOURUSERNAME/.wine/drive_c/SWSetup/sp90206/N75_0133.bin /mnt/Hewlett-Packard/BIOS/New/
# sync 
# sudo umount /mnt

And maybe remove wine + deps
# sudo apt-get remove wine-stable && apt-get autoremove

Reboot machine, press F10 during boot to enter BIOS, update from local media
Note that boot from USB must be enabled or the BIOS/UEFI will fail to find the firmware file.

infelizmente não funciona no modelo HP Pavillion 2100 Series, nem no windows, nem no linux
