5-18     Chapter 5:  BIOS Setup configuration
Plug and Play OS
When this parameter is set to Yes, BIOS initializes only Plug 
and Play boot devices, then the Plug and Play operating 
system takes care of the other devices. When set to No, 
BIOS initializes all Plug and Play boot and non-boot devices. 
Set this parameter to Yes if you are using the Windows 95 
operating system. Set it to No if you run any other operating 
system. The default setting is Yes.
Reset resource assignments
Set this parameter to Yes to avoid IRQ conflicts when 
installing non-Plug and Play cards. This clears all resource 
assignments and allows BIOS to reassign resources to all 
installed Plug and Play devices the next time the system 
boots. After clearing the resource data, the parameter resets 
to the default setting No.
Before you install non-Plug and Play cards, set this 
parameter to Yes, exit Setup and turn off the computer. Then 
refer to “Installing ISA cards” on page 7-5 for instructions on 
installing non-Plug and Play adapter cards.
Using other configuration utilities
You can use Setup to view or change configuration settings 
for most of your factory-installed hardware. If you install new 
hardware, however, you might need to use other 
configuration utilities.
Windows 95 includes a Device Manager utility to help you 
view or change the system resources used by the hardware 
installed in your computer. See the section “Using the 
Windows 95 Device Manager” on page 6-4.
When you purchase new hardware to install in your Aptiva 
computer, a configuration utility or new drivers may come 
with the new hardware. See the documentation that comes 
with the new hardware for instructions.
