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.
Clear ESCD
This item allows you to clear ESCD. Available options are Disabled an d
Enabled. Default value is Disabled.
Resources Controlled By
When selecting Auto(ESCD), BIOS will automatically config ure all the boot
and PnP (Plug & Play) compatible devices and assig ns system resources like
IRQ 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 config ure the system by yourself, select Manaul.

IRQ Resources
This item is adjustable only when Resources Controlled By is set to
Manual. Press <Enter> and you will enter the sub-menu of this item. The
item lists IRQ resources and allows you to set each IRQ a type depending on
the type of device using the IRQ. Setting s: PCI/ISA PnP and Legacy ISA.
PCI/VGA Palette Snoop
PCI VGA palette is the set of colors currently used by the video device.
Some special VGA cards may not show colors correctly and need to look
into the video device' s VGA palette to determine what colors are in use.
Then you have to turn on the palette " snoop" , permitting the palette
reg isters of both VGA devices to be identical. The setting must be set to
Enabled if any non-standard VGA adapter card, such as MPEG card,
installed in the system requires VGA palette snooping .
?
Note: IRQ (Interrupt Request) lines are system resources allocated
to I/O devices. When an I/O device needs to gain attention of the
operating system, it signals this by causing an IRQ to occur. After
receiving the signal, when the operating system is ready, the
system will interrupt itself and perform the service required by the
I/O device.
