Slow Performance with 16-Bit PC Card Network Adapter (277710)


The information in this article applies to:

  • Microsoft Windows CE Platform Builder 2.11
  • Microsoft Windows CE Platform Builder 2.12
This article was previously published under Q277710

SYMPTOMS

Network performance is slower than expected when you use a 16-bit PC Card network adater, because the adapter receives an 8-bit (instead of a 16-bit) input/output (I/O) window.

CAUSE

The Network Driver Interface Specification (NDIS) PC Card code does not check to determine whether a network adapter supports 16-bit I/O access, resulting in suboptimal performance for these adapters

RESOLUTION

A supported software update is now available from Microsoft as Windows CE 2.11 Core OS QFE 30. To resolve this problem immediately, click the following article number for information about obtaining Windows CE Platform Builder and core operating system software updates:
