Maybe you shouldn't call it BIOS? I thought this was a BIOS mod.

How to make my OS compatible with BiOS.

The OS Installer program should write two new lines in boot list file (boot.lst).
Should write in the first line the system name and in the second line the location of OS bootloader (file that launch OS)

Example:

Craft OS 1.4
/rom/programs/shell
Another OS
/AOSBOOT

Tips
  • The os script should be saved in a folder.
  • Only save in main folder the bootloader file.
  • Startup file is used by BiOS. (Use another file name to bootloader)

BiOS are much simpler and occupies less than AxBoot. Wait for new Versions.
