The mapping between BIOS drives and FreeBSD drivers/unit numbers is non-obvious -- in particular in your case. The Zip drive is BIOS ID 0x84. The possible guesses for 0x84 are: sd0 (with four wd's installed) sd1 (with three wd's and one lower ID sd installed) sd2 (with two wd's and two lower ID sd's installed) sd3 (with one wd and three lower ID sd's installed) sd4 (with no wd's and four lower ID sd's installed) So now guess about the chance the bootstrap might have assumed your configuration right. :) You can however use the most recent bootstrap which allows the distinction between BIOS ID (to load the kernel from) and BSD driver/unit (to mount the root device on). Since you can load the bootstrap from a floppy, getting the boot floppy image from the May SNAP might help you. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
