WordPerfect® 5.1 for DOS

Problem

Symptoms: The customer's computer locks when he tries to enter WP with QEMM 5.0 running on the Novell network. If the customer unloads QEMM, it is possible to enter WP. Startup options do not help (/NC/NK, /32, etc.) The QEMM card and the Novell network card share memory in high conventional memory. The QEMM page frame is set to same setting as the network card setting to share memory. Solutions: The network and the expanded memory manager (EMM) cannot share the same memory. The network requires 16K of contiguous memory region; the EMM page frame requires 64K contiguous memory region; it is not possible for these two programs to share the same memory location -- in fact, they can't even overlap. If they share or overlap memory regions, the computer is sure to lock. How/Why: When WordPerfect is trying to talk to the expanded memory through the page frame and the network card is trying to send/receive information, the two collide and cause either lockups, network disconnection, and many other different combinations. If you exclude the network card, the memory manager usually will work around that region that the network card is using.
