Pci 1130 Features - Acer Extensa 900 Series Maintenance Manual

8-, 16-, and 32-bit cards using full 32-bit PCI cycles for maximum performance.
Independent 32-bit write buffers allow fast-posted writes to improve system-bus
utilization.
An advanced CMOS process is used to achieve low system-power consumption while
operating at PCI clock rates up to 33 MHz. Several low-power modes allow the host
power-management system to further reduce power consumption.
