2. ISA Plug and Play (PnP) Extension
Unlike PCI cards which 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 OSes, such as
Windows 95. Under Windows 95, the motherboard BIOS must have ISA
PnP extension to support the new ISA PnP cards.
3. 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.
3.5 Onboard PCI EIDE
The PCI EIDE controller is part of the MVP3 chipset. It supports PIO
mode 3/4 and bus mastering . The peak transfer rate of PIO mode 3/4 can
be as high as 17MB/sec. Using HDDs that support bus mastering, the
peak transfer rate can reach 22MB/sec. There are two IDE connectors,
primary IDE and secondary IDE. With two devices per connector, up to
four IDE drives are supported. The MVP3 also supports Ultra DMA/33,
a new “synchronous DMA” protocol for faster data transfers.
3.6 Onboard Multi-I/O
The onboard multi-I/O chip, Winbond W83877, supports two 16550
UART-compatible serial ports, one high speed EPP/ECP parallel port
and one floppy controller. The floppy controller supports 2.88MB
format. The I/O port addresses of the serial and parallel ports are
programmable via BIOS set-up.
3.7 Onboard CPU Temperature Sensor
The AD22105 IC on the motherboard is a temperature sensor for the
CPU. When the CPU temperature exceeds threshold value, the CPU
slows down automatically to allow it to cool down to a safe level.
