12/22   Any tips for bringing a machine back to life after some sort of
        ACPI-related badness?  It's new Dell, FreeBSD-5.2RC1, and I tried
        acpiconf -s 3.  It shut down and now I can't even get the thing to
        POST-- no vid display, no beeping, just the power light on and the
        disk light blinking.  I know/knew the risks of running -CURRENT, just
        looking for any advice as to how to reset the mobo.  TIA.
        \_ How do you know that your motherboard or your cpu didn't fry?  Rip
           the mobo out and install a spare. If it exhibits the same problem
           chances are it's the CPU (potentially it could be memory, but if it
           was you'd see the POST beeping at you about bad memory).  If it is
           indeed a screwed up ACPI (I've never seen this happen) then you can
           try ripping out the clock battery, waiting for two minutes, and
           sticking it back in. BIOS should revert to factory setting. If you
           can get the manual to your mobo then there should be a jumper short
           you can do to reset the BIOS, which is the "correct" way of doing
           things since you may or may not be able to do the clock battery
           thing. (Although I haven't seen an encased NVRAM with builtin batt
           for some years).  Keep in mind that ripping out the clock battery
           doesn't guarentee the BIOS settings will reset, the BIOS may have a
           large capacitor associated with it to keep it alive for some time (on
           the order of minutes/hours). It could also store stuff in flash, then
           you're SOL until you dig up the manual for the proper jumper
           settings.
           \_ If it's a new dell, it should have a service tag (series of
              letters and numbers) you can enter in on the Dell website and get
              to the page of drivers/manuals, etc.
        \_ Ah but, did you know the risks of running FreeBSD?
        \_ There may be a jumper to reset the CMOS.  I had to do it on an
           Abit BH6 recently when I didn't know the BIOS password.  Look
           on the circuit board for something resembling this.
