3.4 BIOS
The BIOS on the MI5VP4 motherboard provides the standard BIOS
functions plus the following additional features:
1. ISA Plug and Play (PnP) Extension
Unlike PCI cards that are Plug and Play, ISA cards require setting
jumpers to resolve hardware conflicts. To make a computer system
PnP, an ISA PnP standard is established and supported by new
operating systems, such as Windows 95. Under Windows 95, the
motherboard BIOS must have an ISA PnP extension to support new
ISA PnP cards.
2. Power Management
The power management feature provides power savings by slowing
down the CPU clock, turning off the monitor screen and stopping the
HDD spindle motor. The BIOS fully conforms to ACPI (Advanced
Configuration and Power Interface) specification.
3.5 Onboard VGA
The Apollo MVP4 Graphics Controller is a highly integrated display
control device that incorporates a 64-bit 3D/2D graphic engine and video
accelerator with advanced DVD video capability. It provides a flexible
and high performance solution for graphics and video playback
acceleration for various color depth and resolution modes. It supports a
full AGP implementation that include direct access of the system memory
by the 3D engine to provide increased texture memory.
3.6 Hardware Monitoring
The VIA VT82C686A chip has a built-in hardware status monitoring
function that monitor several hardware parameters including power
supply voltages, fan speeds, and temperatures, which are very important
for a high-end computer system to work stable and properly. This
function is used together with System Monitor utility or the optional Intel
LANDesk Client Manager utility.
3.7 Onboard Multi-I/O
The multi-I/O function is built in the VIA VT82C686A chip supports a
keyboard controller, two serial ports, one parallel port, one floppy
controller and one IrDA port. The serial ports are 16550 UART
compatible. The parallel port features high-speed EPP/ECP mode. The
floppy controller supports up to 2.88MB format.
