[SeaBIOS] Use SeaBIOS as UEFI CSM

[Paul Menzel]

Dear SeaBIOS folks,

Colleagues from another institute have the problem, that the PC vendors 
started to remove the CSM (legacy BIOS) option from their UEFI firmware. 
A lot of organizations still use the CSM (legcacy BIOS) option to deploy 
their systems.

I’d like to recommend SeaBIOS to them, but I only found instruction for 
doing that with OVMF [1].

Do you know of a how-to for UEFI firmware, which is shipped on hardware? 
 From that iPXE should be started.

Kind regards,

Paul
