This is just a small collection of transformers that I’m currently using - or that I’ve looked into - and their relevant characteristics (note that relevant characteristics means relevant to me, this is not a general statement).

Booting FreeBSD on the Lenovo X260 (and similar ThinkPads): Legacy Pitfalls and the EFI Fix

Booting FreeBSD on older ThinkPads can be trickier than expected. When moving a GPT-partitioned, ZFS-encrypted SSD from an older HP laptop to a Lenovo X260, the system refused to start in legacy BIOS mode - even with all the usual boot hacks applied. Hours of troubleshooting revealed that the common lenovofix MBR trick wasn’t enough. The solution turned out to be switching over to UEFI boot with a small EFI system partition. This short guide shows the exact steps - from reorganizing partitions to installing the FreeBSD bootloader - and points out small adjustments like Wi-Fi interface renaming. If you’re trying to get FreeBSD running smoothly on an X260 or similar ThinkPad, this walkthrough may save you time and frustration.
