Title:  Workstation Shell Interrupt and Memory Conflict with IBM EGA Card

We have discovered two potential conflicts between workstation shells and
IBM Enhanced Graphics Adapter (EGA) cards installed in workstations.  The
conflicts apply to the following software releases:

     Advanced NetWare 68 V2.0
     Advanced NetWare 86 V2.0
     Advanced NetWare 286 V2.0
     Advanced NetWare 286A V2.0
     Advanced NetWare 68 V2.0a
     Advanced NetWare 86 V2.0a
     Advanced NetWare 286 V2.0a
     Advanced NetWare 286A V2.0a
     Advanced NetWare 68 V2.01
     SFT NetWare 286 V2.0a
     SFT NetWare 286A V2.0a
     Advanced NetWare 286 V1.02
     Advanced NetWare 286A V1.02

POTENTIAL INTERRUPT CONFLICT -- The potential for conflict is due to the
fact that the workstation shell may use IRQ 2 (depending on the LAN
hardware) and the EGA software is also configurable to IRQ 2.

POTENTIAL MEMORY CONFLICT -- The potential for conflict is due to the fact
that the workstation shell sets up a memory buffer at D000:0 for some
network types and the EGA card can also allocate memory at D000:0.

The potential conflicts apply to the following networks:
