I noticed on the last collection done during the 2007 collection season that the MISI high speed D/A computers were having random data drop issues. After a couple of days of searching out the problem (trying various software changes, os slimming, scheduler hacking) it turns out that the BIOS on each box wasn't clocking the processor at the maximum possible frequency for the installed processor (Pentium 4 2.4Ghz) It doesn't appear that the BIOS batteries are dead as the real time clock is still keeping time - something caused the processor configuration to return back to it's defaults. Upon fixing the clocking frequencies MISI returned back to normal operational behavior. Since there isn't an easy way to tell if the clocking frequency is right during flight configuration I'm implementing a check in the misicontroller code to make sure that we're running up to speed, the check will report back to the cadence computer if the values have reset themselves again.
