Sometime after recently upgrading a Toshiba P4 Laptop from UURollup-v11-w20130323 stable to UURollup-v11-d20130902, I began to notice excessively long bootup times, approximately 3-5 times longer than average.
At the time, I was preoccupied with other system configurations and held off on any further troubleshooting. Today, during a visit to safe mode, I watched the drivers load, noticing the system began to hang immediately after agp440.sys, attempting to load two files which looked nothing like drivers.....shown below:
A quick search confirmed that neither of these two files existed on my system partition. Going a step further, I ran searches for all system files, containing these names, including registry without a single hit. WTF!
A broader search in all partitions, on both the Laptop and Desktop, returned hits for only drvmain.sdb, located in XP system partitions under \WINDOWS\AppPatch\, \WINDOWS\system32\dllcache\ and various XP installation sources.
Online sources indicated this problem is usually associated with XP or Server 2003 compatibility files and tables used by the OS during driver loading. My identical error is best described in the following Server blog:
Is this a code issue, a file import failure, or just another Microsoft moment?
