I have performed many upgrades without a hitch. However, the PMON ext2fs access code is fragile, and may not load the bootblocks correctly if the boot block image gets put in a too-trick-for-retarded-code location. Of course, when this happens, PMON will happily tell you it has loaded the binary, but actually loaded garbage from different sectors than those the binary is installed in. Did I mention how high quality that PMON code is? My best advice would be to backup your system and reinstall. If this is not an option, you *might* (as in, ought to) be lucky if you ``newfs_ext2fs wd0i'' and copy /usr/mdec/boot to the root of the ext2fs filesystem (boot bsd.rd from the network; newfs_ext2fs is on the installation media filesystem, but /usr/mdec/boot isn't, you'll need to copy it from either the network or your BSD filesystem, which you can mount from bsd.rd) Miod
