Problem

Symptoms: When the customer is loading large documents or printing, the screen locks and a message "3C523.Wait_SCB: SCB Command Not Clear" comes up. The customer must then reboot. The problem happens randomly, but it can be duplicated consistently with the /R option. It cannot be duplicated with /NE, so it seems to be related to expanded memory. The customer has an IBM expanded memory drivers: XMAEM.SYS and XMA2EMS.SYS. He is using the Novell version 2.15. Solutions: The customer had his expanded memory page frame set up so that it was conflicting with his network card. He had a 3Com 3c523 Etherlink card, and that was the base for the generation of the message. Basically, the tester found the conflict by looking at his CONFIG.SYS file and then looking at what came up when he executed IPX.COM. When IPX is run, it displays the network card's current settings.
