I did some work to fix this back in 2019, but the patches were never merged: https://www.gulbra.net/freebsd-bhyve/ > 2. Instead of using uefi-csm, can bhyve boot SeaBIOS? I've tried -l > bootrom,/tmp/seabios/out/bios.bin but I'm not sure that is working. The problem is that you will need an emulated video card with its own Video BIOS, unless you pass through a real video device. My patches will give you that, but the code is non-trivial and has not been touched in almost five years. It would take some work to bring it up to date with the current baseline. I have been lingering on this list in the hope that someone with commit privileges would take an interest in BIOS booting and VGA graphics, but I guess most people only need UEFI nowadays. /Henrik
