Aliases for kernel image, its functionality and options.

tomem


  Loads kernel and whole image in yaboot, then starts system normally. After booting, CDROM will not be needed anymore. Requires 128Mb or more of ram. Should work with cdroms not connected to pmac-ide too.

fromcd


  Loads kernel and initrd, starts system. In initrd searches for cdrom, mounts it and mounts image from it. CDROM will be needed (and locked), because image is not copied to memory. Should run with 32Mb of RAM. Only popular IDE/SCSI controllers are supported.

tomempost


  Like 'fromcd' loads kernel and initrd, starts system. In initrd searches for cdrom, mounts it, and then, copies image to memory and mounts it from there. Umounts CDROM so drive can be used. Requires 128Mb of ram. Only popular IDE/SCSI controllers are supported. This option should run faster than 'tomem' if you have DMA switched on, try adding ide1=ata66 or something similar (check ide help).

memtest


  Loads kernel and initrd. Searches for cdrom and mounts image as root (/) read-only, umounts initrd and flushes ramdisk. Starts memtester with all memory minus 3Mb and reduces amount by 0.5Mb until memtester will not be killed.
