> Disk drivers could be provided by BIOS/UEFI They can, but I don't want direct access to a disk driver. I don't want to care about the hardware, or even what file system is in use. I want to write a log file to this folder on this disk. Once the BIOS/UEFI starts providing that level of abstraction, how is it different than an operating system? Having an operating system means there is a lot less code I have to write, because all the nitty gritty details of networking, talking to hardware, and all that other stuff is already taken care of for me. Someone else already invented the wheel so I don't have to.
