It does two things. 1) Using a modified version of rdev.c, we can set the startup video mode of an image. No more recompiling if you want to change modes. Example: vidmode /dev/fd0 1 Here, vidmode is just a link to the new rdev.c pgm enclosed. 2) Set the ramdisk size to nonzero to boot up using a ramdisk. Loading starts from the 512K mark. Like so: ramsize /dev/fd0 620 Following are the patches, Let me know of any problems.
