Halt should trigger the halt trap, which on an Alpha means putting you into the boot monitor. For the PC, it means putting you in a state where you can hit "DEL" to get the setup, or "CTRL-A" to get into the Adaptec BIOS configuration, etc.. It's not FreeBSD's fault that (most) PC hardware is too stupid to have a boot-ROM that lets you configure things before triggering the boot loader, unless you overrice the default behaviour with keystrokes while it's pounding away at things. Also, I think the correct flag is "-x", not "-p", from a historical (Sony NeWS, NeXTStep, and A/UX, et. al.).
