Comments on Writing Boot Sector Code

It may work with UEFI if it's set to compatibility mode.

That's correct. UEFI firmware will execute a PE image (the same format that Windows executables use) on a FAT32 file system, and can access UEFI services to execute a kernel.
The UEFI firmware may support a CSM (compatibility support module) that can boot a legacy BIOS loader.

This is a great introduction to writing boot sector code! Really brings back memories. So awesome.

Boot sector programming has always seemed like one of the cooler ways to play with writing lower level code, but am I wrong to assume it won't work on systems with UEFI?
