Try inhibiting as many modules from loading as possible (boot single user if you have to), booting, then moving /boot/kernel out of the way (its a directory), then rebuild & reinstall the kernel again. Also move /modules out of the way since those aren't usable anymore. Is the NVidia module being used? -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
