10 ASUS A7V User’s Manual2. FEATURESPerformance2. FEATURES2.1.2 Special Features• ACPI Ready: Advanced Configuration and Power Interface (ACPI) providesmore Energy Saving Features for operating systems that support OS Direct PowerManagement (OSPM) functionality. With these features implemented in the OS,PCs can be ready around the clock, yet satisfy all the energy saving standards.To fully utilize the benefits of ACPI, an ACPI-supported OS, such as Windows98 must be used.• Easy Installation: Incorporates BIOS that supports autodetection of hard diskdrives, PS/2 mouse, and Plug and Play devices to make the setup of hard diskdrives, expansion cards, and other devices virtually automatic.• Suspend and Go: Suspend-to-RAM (STR) provides maximum power savingsas an alternative to leaving the computer ON and QuickStart™ so that you donot have to wait for a long time for system bootup.• New Compliancy: Both the BIOS and hardware levels of this motherboard meetthe stringent requirements for PC 99 certification The new PC 99 requirementsfor systems and components are based on the following high-level goals: Sup-port for Plug and Play compatibility and power management for configuringand managing all system components, and 32-bit device drivers and installationprocedures for Windows95/98/NT .

(See 4.4.2: I/O Device Configuration in BIOS setup).2.1.4 Performance Features• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-ter busses to the memory and processor.• High-Speed Data Transfer Interface: This motherboard features the Promise®Ultra DMA/100 Chip IDE controller chipset that supports UltraDMA/100 and datatransfer rates to 100MB/s. UltraDMA/100 is backward compatible with DMA/66, DMA/33, and DMA and with existing DMA devices and systems so there isno need to upgrade current EIDE/IDE drives and host systems. (UltraDMA/66and UltraDMA/100 require a 40-pin 80-conductor cable to be enabled.)• VCM/SDRAM Optimized Performance: This motherboard supports a new gen-eration memory, NEC’s 64Mb Virtual Channel Memory (VCM) Synchronous Dy-namic Random Access Memory (SDRAM), which is compatible with the industry
