The information in this article applies to:
- Microsoft Windows 95 OEM Service Release, versions 2, 2.1
-------------------------------------------------------------------------------
SYMPTOMS
========
Devices behind a PCI-to-PCI bridge on a P6-based computer will be disabled. The
devices appear in Device Manager with either an exclamation point in a yellow
circle or a red "X," indicating a problem with the device.
CAUSE
=====
OEM Service Release 2 (OSR2) does not support the configuration of devices
behind PCI-to-PCI bridges on P6-based computers. The BIOS in P6-based computers
is required to configure the resources for devices behind the bridge.
MORE INFORMATION
================
OSR2 can configure devices behind PCI-to-PCI bridges in protected mode on
Pentium- or 80486-compatible x86 processor-based computers (processors prior to
the P6). Therefore, it is possible to access devices behind the PCI-to-PCI
bridge without BIOS support for resource configuration. Accessing the devices in
real mode is not possible without the support of the BIOS.
NOTE: The retail release of Windows 95 (version 950) does not support the
configuration of devices behind PCI-to-PCI bridges, requiring the BIOS to
configure all devices behind PCI-to-PCI bridges.
