®
and AMD
K5/K6 processor. The mainboard also supports four 32-bit PCI
(Peripheral Component Interconnect) Local Bus standard slots.
®
The mainboard uses the highly integrated Intel
83430TX chipset to support
the PCI/ISA and Green standards, and to provide the Host/PCI bridge. The
®
Intel
82430TX chipset integrates all system control functions such as ACPI
(Advanced Configuration and Power Interface). The ACPI provides more
Energy Saving Features for the OSPM(OS Direct Power Management)
®
function. The Intel
82430TX chipset also improves the IDE transfer rate by
supporting Ultra DMA/33 IDE that transfer data at the rate of 33MB/s.
The mainboard also supports the LM78 and LM75 Hardware Monitor
Controller which are optional functions. The LM78 function includes: CPU
chassis/power fan control, CPU temperature detect and protect, system
voltage detect and chassis intrusion detect. The LM75 function includes:
CPU overheat warning.
