I recently purchased a used Lenovo Thinkstation E32 computer. I always update the BIOS when I get a new machine — here is how to do it using a bootable USB stick. No Windows required.
First we need the BIOS update ISO, then we are going to use
geteltorito to extract the bootable image and write it onto a USB stick.
geteltorito on Arch Linux:
$ yay -S geteltorito
Extracting the bootable image:
$ geteltorito.pl -o thinkstation-e32.img fbj9dfusa.iso Booting catalog starts at sector: 18 Manufacturer of CD: FBJTDFA Image architecture: x86 Boot media type is: harddisk El Torito image starts at sector 304 and has 32130 sector(s) of 512 Bytes Image has been written to file "thinkstation-e32.img".
Writing the image onto the USB stick:
$ sudo dd if=thinkstation-e32.img of=/dev/sdb status=progress 9232896 bytes (9.2 MB, 8.8 MiB) copied, 1 s, 9.2 MB/s 32130+0 records in 32130+0 records out 16450560 bytes (16 MB, 16 MiB) copied, 4.24189 s, 3.9 MB/s
Sync disk cache, just to be safe. This makes sure that all write operations to the USB stick is complete.
Now we just need to boot from the USB stick we just created, press F12 to enter the boot menu on the Lenovo machine.
- This also worked for HP Z4 G4 BIOS update — using the
- And will probably work for a lot of similar applications.
