Re: Trouble rebooting Tyan Thunder K7 (S2462UNG)

Sorry that I did not explain myself better the first time.
The other OSes on this machine _do_ initialize a
cold boot. Here is how they _all_ reboot: screen
immediately goes black, hd light comes on as
memory is ECC checked, hd light goes off and BIOS
post screen comes up (monitor is now on again),
Adaptec SCSISelect screen comes up, BIOS issues
single beep and boots into GRUB. This is the way
that _all_ versions of linux reboot with _all_ reboot
parameters: screen hangs (but still has text on it, ie.
the reboot messages) for at least 15-30 seconds,
screen then goes blank, hd light comes on but _not_
for ecc check (during ecc check nothing is accessed
except for memory) instead the system goes straight
into SCSISelect once the screen goes blank and the
hd light comes on (this is evident because during
normal boot SCSISelect is the stage at which the hd
light is on and each SCSI device is accessed in
order), once SCSISelect has polled every id on the
system it tries to hand back off to the BIOS which
was apparently never initialized correctly during a
Linux reboot since it issues a very weird series of
eight or so BIOS beeps and then just sits there, the
ecc memory is never polled, the BIOS post screen
never comes up, the monitor never goes active
again, the system is just hung at a black screen until
I hard reboot it. Other OSes _do_ perform a reboot
in which ecc memory is polled however, so that
does not seem to be the problem here. Thanks for
any more help anyone can offer.
