10 TI5VG Pentium VP3 ATX Motherboard User’s Manual
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 VP3 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 VP3 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 Optional Hardware Monitoring Device (LM78)
The LM78 is a data acquisition system for the hardware monitoring of the
PC and is used to monitor power supply voltages, temperatures and fan
speeds. It has an on-chip temperature sensor and also features Chassis
Intrusion Input. The LM78 is compatible with the optional LDCM
(LANDesk

Client Manager) software from Intel.
