PnP/PCI Configurations
PNP OS Installed
When set to YES, BIOS will only initialize the PnP cards used for booting
(VGA, IDE, SCSI). The rest of the cards will be initialized by the PnP operat-
®
ing system like Windows
98. When set to NO, BIOS will initialize all the
PnP cards. So, select Yes if the operating system is Plug & Play aware.
Reset Configuration Data
The ESCD (Extended System Configuration Data) is a method that the BIOS
uses to store resource information for both PNP and non PNP devices in a
bit string format. When Enabled, the system will rebuild ESCD and you will
see the message "ESCD Update Successfully" on boot up.
Resources Controlled By
When selecting Auto(ESCD), BIOS will automatically configure all the boot
and PnP (Plug & Play) compatible devices and assigns system resources like
IRQs to these devices. However, this feature means absolutely nothing
unless you are using a Plug and Play operating system such as Windows
98. If you want to configure the system by yourself, select Manaul.
IRQ/DMA Resources
The items are adjustable only when Resources Controlled By is set to
3-26
