About

A x86-bootloader for danrlOS using Disk Address Packets for boot-media access. BIOS Interrupt 0x13 with register AH set to 0x42 allows extended reading of sectors from a drive. This method allows a bootloader to load data from a drive without calculating head and track numbers. Moreover, it is possible to boot a kernel that resides at the end of a large drive. Unfortunately, most bootloaders still use the old and limited method Interrupt 0x13 with AH set to 0x02.
