3.4 BIOS
The BIOS on the TI5VGA 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 VT82686A 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 VT82686A also supports UDMA33
and UDMA66, a new “synchronous DMA” protocol for faster data
transfers.
3.6 Onboard Multi-I/O
The multi-I/O is integrated in the VIA chipset that 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.
