2.1.2 Specifications–Optional Components
The following onboard components are optional at the time of purchase:
• Onboard Audio: C-Media Audio Chip CMI8738 supporting the latest PCI 6
channel and HRTF 3D Audio sound circuitry. A software package helps setup
the multi-channel PC sound system.
• Promise
®
chip: Available on the TUSL2, the Promise IDE controller
chip supports the ATA-100 protocol and Ultra DMA/100 data transfer speeds.
The chip also delivers reliable redundancy and stable performance to RAID
levels 0 or 1. Data “striping,” or RAID 0, improves speed performance as
I/Otasks are spread between two hard disk drives. Data “mirroring,” or RAID 1,
improves system fault tolerance as the protocol optimizes two identical hard
disks to write data to each other.
2.1.3 Performance
• UltraPerformance: Onboard IDE Bus Master controller with two connectors that
support four IDE devices in two channels. Supports UltraDMA/100, UltraDMA/
66, UltraDMA/33 (IDE DMA Mode 2), PIO Modes 3 & 4, and supports Enhanced
IDE devices:DVD-ROM, CD-ROM, CD-R/RW, LS-120, and Tape Backup drives.
• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter buses to memory and processor.
• SDRAM Optimized Performance: This motherboard supports PC133-com-
pliant Synchronous Dynamic Random Access Memory (SDRAM), which increases
the data transfer rate to 1066MB/s max.
• ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple-
mented on all ASUS smart series motherboards. ACPI provides more Energy
Saving Features for operating systems (OS) supporting OS Direct Power Man-
agement (OSPM). With these features implemented in the OS, PCs can be ready
around the clock, yet satisfy all the energy saving standards. To gain all the
benefits, an ACPI-supported OS, such as Windows 98/2000/ME is required.
• Suspend and Go: Suspend-to-RAM (STR) provides maximum power savings
as an alternative to leaving the computer ON and QuickStart™ so that you do
not have to wait for a long time for system bootup.
• New Compliancy: Both the BIOS and hardware levels of the motherboard meet
the stringent requirements for PC 99 certification. The new PC 99 requirements
for systems and components are based on high-level goals: support for Plug and
Play compatibility and power management for managing all system compo-
nents, and 32-bit device drivers and installation procedures for Windows 95/98/
NT. Color-coded connectors and descriptive icons make identification easy.
