DAVICOM DM9PCI NDIS 2 Driver Installation Guide for WFW 3.11

Microsoft introduced WFW 3.11 as a 32-bit architecture which uses NDIS 3
as its network device driver. Figure 1. depicts the WFW 3.11 system
architecture when NDIS 3 MAC driver is used.

The NDIS 2 drivers are real-mode drivers, and reside in the MS-DOS
conventional memory. If we intend to use real-mode driver in 32-bit
WFW 3.11 environment, 2 additional drivers are needed. The NDIS2SUP.386
is the NDIS 2 to NDIS 3 mapping support layer and the NDIS2HLP.SYS driver
is the real-mode stub for the NDIS2SUP.386 VxD and assist in the binding
process between real-mode NDIS 2 network adapter drivers and NDIS 2 protocols.
Figure 2. shows this configuration.

* Install NDIS 2 MAC driver in the Windows for Workgroup 3.11 Environment

1. Install WFW 3.11 network componets first
2. Add DM9PCI NDIS 2 MAC driver to adapter list.
3. Modify CONFIG.SYS manually and make sure that the following lines appear

      DEVICE=C:\WFW311\IFSHLP.SYS
      DEVICE=C:\WFW311\PROTMAN.DOS /I:C:\WFW311
      DEVICE=C:\WFW311\DM9PCI.DOS
      DEVICE=C:\WFW311\NDISHLP.SYS
