(K)e(R)(N)e(L) (L)(O)(A)(D)er v1.0.1f

Resources:

• Interrupt 0x10 AH=0x0E
• Interrupt 0x13 AH=0x02

How to compile:

• Whenever you change the config (first lines of krnlload.asm) you'll have to re-compile
• To re-compile you will need nasm installed how to install it on debian based distros:
  • root privileges required
    sudo apt install make
make debian-setup
• How to install it on arch based distros:
  • root privileges required
    pacman -S make
make arch-setup
    
    
• To compile you need to run this command:
  make compile

And just like that krnlload is compiled!

How to use:

• Place your kernel in the same directory you have krnlload.bin
• Note that the kernel must be compiled to a binary
• To use krnlload you'll have to get your kernel binary name it however you want but you have to remember that in this example it is showed as kernel.bin
cat krnlload.bin kernel.bin > output.bin
  This outputs a binary that is ready to use

It's not working:

• If KRNLload is not working try these things:
• Go into the first lines of krnlload.asm and change KERNEL_START_SECTOR to 0x02 (Like this: %define KERNEL_START_SECTOR 0x02)
• Go into the first lines of krnlload.asm and change SECTORS_TO_READ to a big number, the number depends on how big you're kernel is we assume that you know about sectors since you are making an operating system (Like this: %define SECTORS_TO_READ 32)

Versioning scheme:

• Let's breakdown this:

  KRNLload v1.0.0d
• KRNLload is the name of the bootloader
• v1.0.0 is the version
• d is the dev channel

• Now this:

  KRNLload v1.0.0f
• KRNLload is the name of the bootloader
• v1.0.0 is the version
• f is the final release channel
