• UltraPerformance: Onboard Ultra160/Ultra2 (depending on model) dual chan-
nel SCSI controller with two connectors that support 30 Ultra160/Ultra2 SCSI
devices in two channels.
• Dual Speeds: CPU frequency can operate at either 133MHz or 100MHz de-
pending on the CPU installed.
• High-Speed Data Transfer Interface: SCSI transfers using Ultra160/Ultra2
(depending on model) dual channel SCSI controller can handle rates up to 160MB/
s or 80MB/s. Ultra160/Ultra2 is backward compatible with slower SCSI de-
vices so that older SCSI devices are not wasted. (Ultra160/Ultra2 SCSI cables
have twisted pairs compared to flat ribbon cables used in older SCSI standards.)
• Advanced 64-bit PCI: Maximizes IO bandwidth for the next generation of 64-
bit PCI cards, supports up to (2) full 64-bit 66/33MHz PCI busses, and supports
up to (5) 32-bit 33MHz PCI busses.
• Full Peer-to-Peer Support: Allows full peer-to-peer transactions between PCI
busses and increases options for intelligent IO and Server Management cards.
• SDRAM Optimized Performance: This motherboard supports PC133 “regis-
tered” Synchronous Dynamic Random Access Memory (SDRAM), which increases
the data transfer rate to 1064MB/s max
• ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple-
mented on all smart series motherboards ???. ACPI provides more Energy
Saving Features for future operating systems (OS) supporting OS Direct Power
Management (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 Windows
98, must be used.
• New Compliancy: Both the BIOS and hardware levels of the motherboard meet
the stringent requirements for SDG2.0 certification. The new SDG2.0 require-
ments for systems and components are based on the following high-level goals:
support for Plug and Play compatibility and power management for configuring
and managing all system components, and 32-bit device drivers and installation
procedures for Windows NT/2000. Color-coded connectors and descriptive icons
make identification easy as required by PC99.
