Simple and fast bootloader

How to compile

  • First run compile script, by running ./compile. Compile script will create boot_fin.img and LINKSCND.BTT images. boot_fin.img is meant to be writen to storage device using dd command: dd if=boot_fin.img of="storage_device" bs=512 count=1
  • After that storage device will contain one FAT12/16 partition that needs to be mounted, and LINKSCND.BTT transfered to it.

Bootloader stages:

  • LinksBoot first stage (boot_fin.img) - Contains basic segment setup code and FAT fs and disk driver for second stage bootloader loading.
  • LinksBoot second stage (LINKSCND.BTT) - Contains full FAT and disk driver, GDT, IDT and A20 setup code, and code to load kernel
