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.
