As a result,the E2200 Series Bus Mastering adapter is given incorrect information from system memory, causing it tofunction improperly. Symptoms of this problem include sporadic packet transmission, and lost networkconnection.To correct this problem, enter the System Setup Utility, and disable CPU Standby Mode. Entering theSystem Setup Utility will vary from system to system depending on the vendor. Note that the CPUStandby Mode setting is the only thing that needs to be changed!1.2 RECONFIGURATION AND DIAGNOSTICSIf you wish to change the E2200 Series adapter’s configuration using the QuickSet Utility, or if you wish torun the Cabletron Diagnostic Program: you must make sure that no E22XX drivers are loaded.
