Biostar M7VIW [27/31] M7viw bios setup

M7VIW BIOS Setup

ESCD will update only when the new configuration varies from the last one. If the Enabled

option is chosen, the system is forced to update ESCDs and then is automatically set to the

“Disabled” mode.

The above settings will be shown on the screen only if “Manual” is chosen for the resources

controlled by function.

Legacy is the term, which signifies that a resource is assigned to the ISA Bus and provides

non-PnP ISA add-on cards. PCI / ISA PnP signifies that a resource is assigned to the PCI

Bus or provides for ISA PnP add-on cards and peripherals.

The Choices: Disabled (default), Enabled.

Resources Controlled By

By Choosing “Auto(ESCD)” (default), the system BIOS will detect the system resources

and automatically assign the relative IRQ and DMA channel for each peripheral.By

Choosing “Manual”, the user will need to assign IRQ & DMA for add-on cards. Be sure

that there are no IRQ/DMA and I/O port conflicts.

IRQ Resources

This submenu will allow you to assign each system interrupt a type, depending on the type

of device using the interrupt. When you press the “Press Enter” tag, you will be directed to

a submenu that will allow you to configure the system interrupts. This is only

configurable when “Resources Controlled By” is set to “Manual”.

PCI / VGA Palette Snoop

Choose Disabled or Enabled. Some graphic controllers which are not VGA compatible

take the output from a VGA controller and map it to their display as a way to provide boot

information and VGA compatibility.

However, the color information coming from the VGA controller is drawn from the palette

table inside the VGA controller to generate the proper colors, and the graphic controller

needs to know what is in the palette of the VGA controller. To do this, the non-VGA

graphic controller watches for the Write access to the VGA palette and registers the snoop

data. In PCI based systems, where the VGA controller is on the PCI bus and a non-VGA

graphic controller is on an ISA bus, the Write Access to the palette will not show up on the
