You could try opening the firmware update's executable as an archive (they are often SFX - self-extracting ZIP archives), extract its contents to a FAT-formatted USB pen drive, reboot the laptop with the pen drive attached and enter the BIOS firmware flash utility (often the F7 key). If you found a firmware update from 2014, your laptop may not be so old it can't update from a USB stick. :) On 16/09/2020 22:50, Rocky Hotas wrote:
This is a very old laptop. I just found a 2014 firmware update (which I'm almost sure had not been installed), but it's only available for Windows, so, having only NetBSD, I couldn't install it.
