The FreeBSD BMs don't behave that way. /boot/mbr just boots the active partition and doesn't change it. The other is described in the "boot0cfg" manpage. > In theory, this should work and be the equivalent of choosing F4, right?: > > boot: 0:ad(0,4,a)/kernel > > BIOS drive 0, ata drive 0, slice 4, partition a, 5.x default boot of /kernel > > Alas, it only bells at me and gives me the same suggested syntax. Wrong; it's not the equivalent. Hitting F4 causes the bootstrap on "s4" to run. This normally starts /boot/loader but in some cases produces your "boot:" prompt. The handbook shows it in a "boot2 Screenshot". I'm unsure why you can't get the "boot:" prompter to transfer you to another slice. Maybe it requires that you pass the kernel some options. You might have better luck asking it to start /boot/loader which provides more gizmos for changing defaults, etc. > Does anyone know the syntax to perform the boot-to-cd from the boot manager feat? Not I. And you're likely to confuse people if you use "boot manager" like that. FreeBSD docs call it the "stage-two bootstrap" or something similar (even though it is seldom the second stage of the bootstrap process).
