APM Does Not Function with NDIS 2 Adapter Driver (127872)
The information in this article applies to:
This article was previously published under Q127872 SYMPTOMS
After you install Windows 95 on a computer that supports Advanced Power
Management (APM), the APM features in Windows 95 do not work.
CAUSE
This behavior occurs if you are using a real-mode (NDIS 2) network adapter
driver in Windows 95.
RESOLUTION
If one is available, use a protected-mode (NDIS 3.1) driver for the network
card. To determine whether a protected-mode driver is available for the
network card, follow these steps:
- Use the right mouse button to click the Network Neighborhood icon and
then click Properties on the menu that appears.
- In the "The following network components are installed" box, click
the network card installed in your computer.
- Click the Properties button. If there is an "Enhanced mode (32-bit
and 16-bit) NDIS driver" option on the Driver Type tab, there is an
NDIS 3.1 driver for the network card. If this option does not exist
on the Driver Type tab, contact the manufacturer of the card to
determine whether updated drivers exist.
MORE INFORMATION
Windows 95 rejects all APM requests if an NDIS 2 network card driver is
installed. Windows 95 does this because the network mapping file (NDIS.VXD)
cannot know in what state the real-mode driver would resume upon resumption
of power.
