CMD PCI-0646U Accessed in Compatibility Mode in OSR2 (170324)
The information in this article applies to:
- Microsoft Windows 95 OEM Service Release 2
- Microsoft Windows 95 OEM Service Release 2.1
This article was previously published under Q170324 SYMPTOMS
When you use an IDE controller based on the CMD PCI-0646U chip set in
Windows 95 OEM Service Release 2 or 2.1 (OSR2), the controller is not
recognized, protected-mode drivers are not loaded, and the controller
is accessed in Compatibility (BIOS) mode.
CAUSE
The CMD PCI-0646U chip set uses some control registers in a different
manner from earlier models of CMD controllers. The Windows PCI driver
accesses these registers in a way that causes it not to recognize this
controller.
RESOLUTIONSTATUS
This problem no longer occurs in Windows 98. To resolve this problem, install the current version of Windows. For information about the current version of Windows, visit http://www.microsoft.com/windows.
