Hi, > Modified files: > sys/boot/i386/boot0 Makefile boot0.s > Log: > The new and improved boot0, v1.1. This version adds the following: > - Autodetection and support of the BIOS EDD extensions to work around the > 1024 cylinder limit on all but really ancient BIOS's. > - To work around some BIOS's which break when EDD is used with older drives, > we only attempt to use EDD if the cylinder is > 1023. > - Since this new code required more space than we had left, expand boot0 to > 2 sectors (1024 bytes) in length. > - Add support for boot0 being multiple sectors using predefined constants. > If boot0 needs to be extended in the future, all that is required is > bumping the NUM_SECTORS constant. > - Now that we have more room to work with, add a few more fs type > descriptions while making others more verbose. Any chance that this could be MFC'd ? If not are there any good reason to not use the new boot0 stuff with FreeBSD 4-Stable (apart from taking care of not rebuilding boot0cfg, libdisk and boot0 with subsequent buildworlds) ? Patrick.
