3.4 BIOS
The BIOS on the MI7VGA 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 AGP Slot
The AGP (Accelerated Graphics Port) slot supports AGP compliant
VGA cards to achieve rich 3D and video graphics display. AGP is a
platform bus specification that enables 3D graphics capabilities
including support for z-buffering, alpha blending and faster texture
mapping.
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 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.
