The Pentium III 600MHz processor will have extended MEMORY longevity through Intel’s ACPP program. Higher speeds will be validated on Up to 2G (2048MB) using RDRAM this product when available. Call for current speed support. MEMORY ORGANIZATION PCI BUS 2 Rambus Channels with 2 RIMMS per channel The LBC8926 provides support for up to 4 - 64 bit PCI cards at 33MHz. Each of these slots can be bus masters. The LBC8926 will also support 32 bit PCI PCI BUS SPEED devices and can fit into any PICMG designed backplane with or without 64 bit 33 or 66MHz - 32 or 64 bits support. BIOS ISA BUS DTI Enhanced PHOENIX BIOS, Plug-n-Play compliant The LBC8926 provides an interface to the ISA bus with DTI’s enhanced PCI IDE buffering to reduce loading issues that can occur with high slot count EIDE support, Ultra 66/33 ATA, bootable CD-ROM backplanes. SYSTEM MONITOR PCI SCSI The LBC8926 includes DTI’s standard system monitor which provides SymBIOS SYM53C896 SCSI environmental monitoring of all system temperatures and voltages Independent Ultra 2 and Fast SCSI Channels (CPU, System, Ambient, and Remote). The system monitor also features DUAL PCI ETHERNET fan/switch monitoring through eight inputs, a built-in two-stage watchdog 10/100 Base-T using Intel’s 82559ER timer, alarming mechanisms for failure reporting, a dedicated serial port for remote communication through a modem or a CPU-to-CPU connection, and a AGP VIDEO with FLAT PANEL SUPPORT general purpose scratch pad area. C&T 69030 with 4MB video memory AGP VIDEO USB The LBC8926 uses the C&T 69000 to provide enhanced 3D graphics UHCI compatible host controller with one port performance and flat panel support. Two megabytes of synchronous graphics memory is built into the 69000. KEYBOARD/MOUSE PORTS PS/2 and /AT internal connectors use determined by jumper setting. ETHERNET The LBC8926 supports two fully auto-negotiating 10/100 Base-T connections, PHYSICAL and full duplex operation which allows data rates to reach 20Mbps and 4.2” x 13.3” 200Mbps. HUMIDITY SCSI 0% - 95% Non-condensing The LBC8926 provides a high performance Low Voltage Differential Ultra-II POWER SCSI interface allowing data transfers to reach 80 MB/s using the SymBIOS TBD SYM53C896 LVD SCSI controller. A second independent SCSI channel supports older fast SCSI devices. www.dtims.com Rev. 1.2 1.800.443.2667 September 2, 2004 All trademarks and tradenames are the property of their respective owners.
