Boot sector programming has always seemed like ln 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?
- leo89 7y agoIt may work with UEFI if it's set to compatibility mode.
- frutiger 7y agoThat'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. EDIT: as pointed out by a sibling comment, the UEFI firmware may support a CSM (compatibility support module) that can boot a legacy BIOS loader.
