Planning for the next major FreeBSD update, I decided I should update the old BIOS first, Lenovo are very good at releasing updates to BIOS/UEFI long after the product has ceased being available.
Suffice to say a quick check of https://pcsupport.leveno.com/gb/en and pumping in the Model No (or device serial no) detailed a list of updates for my hardware a good 5 years newer than the original BIOS that shipped with this box.
However is its non-Windows all the usual update tools where irrelevant. Litterally had to dust down my DVD/CD recordable drive and download the BIOS ISO and burn to CD. A quick dabble to change the boot order and re-enable the original DVD drive and I was finally able to flash the BIOS. All very slow compared to in-windows updates on my other devices.
No major great improvements, but better support for any more modern hardware I might chuck inside like SSD’s in the future.
