8 AI5VP/AI5VPB User’s Manual
3.4 BIOS
The BIOS on the AI5VP/AI5VPB motherboard provides the standard
BIOS functions plus the following additional features:
1. DMI (Desktop Management Interface)
The motherboard supports DMI to enable computer system management in
an enterprise.
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 VPX 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 VPX supports Ultra DMA/33, a new
“synchronous DMA” protocol.
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.
