BootX is a graphical bootloader developed by Benjamin Herrenschmidt, which runs as an application or an extension to Mac OS 8 and 9 that allows Old World Apple computers to dualboot Linux. It uses code derived from quik, a replacement boot loader for PCI-based Old World Apple computers using Open Firmware.
BootX requires a Linux kernel and compressed ramdisk image to be available in the Mac's system folder. It will then automatically choose which partition becomes the root partition.
