You did not specify which/what version of FreeBSD CD-ROM you were attempting this with. IIRC way back then bootable CDs used a floppy-emulation mechanism. If the hardware and its' BIOS is that old a modern day boot CD won't work as it is not emulating a floppy disk any longer. Your best bet would be to locate a FreeBSD version 4.7 disk and try that. A long time ago there used to be included 2 floppy images that could be written out to floppy disks, thus creating bootable floppies. In lieu of not being able to boot from CD-ROM if there is a 1.44MB floppy drive in the box you may be able to boot off the floppies. I'm a little rusty with dim memories, but essentially you want to boot into single user mode. I think it used to be you'd break into the loader by hitting the space bar during the the little "twirlie" period when a '/' is spinning in the upper left corner of your screen. You would need some basic familiarity with vi such as how to do a basic edit and then save the file. Essentially what vipw does is open the password file using vi as the editor. You could then null out the root password by replacing the crypto string in the second field with a * character. When you save the file using vi commands and exit you will see a message about the password database being updated. This is actually a FAQ: http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/admin.html#FORGOT-ROOT-PW Note the instructions for mounting / read-write, and the mount -a. The vipw lives in /usr/sbin, so /usr needs to be mounted in order to use it. -Mike _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
