Trying to run FreeDOS off CF Card on 286 homebrew system --- Question about bootloader and drive geometry information

• kernel

  5 725 8.6 C

  FreeDOS kernel - implements the core MS-DOS/PC-DOS (R) compatible operating system. It is derived from Pat Villani's DOS-C kernel and released under the GPL v2 or later. Please see http://www.freedos.org/ for more details about the FreeDOS (TM) Project. (by FDOS)

  

Looking at https://github.com/FDOS/kernel/blob/master/boot/boot.asm, I see %define statements for this type of information, but I'm not sure how these memory locations are normally populated with proper values. Is this something that Sys does when preparing the CF card? Or should the BIOS populate this information when loading the boot loader?

• format

  1 15 0.0 C

  Disk formatting program -- creates FAT file systems and lowlevel-formats floppy disks. (by FDOS)

  

YouTube user '@pvc' mentioned that this information is populated as part of the format utility. I am currently reviewing the source code for FreeDOS format. I am also reading through the Microsoft Extensible Firmware Initiative File System Specification (fatgen103).
