Allows the use of 500 to 850MHz processors in Intel’s socket 370 (FC-PGA) package. The Pentium III 600, 700, and 850 MHz processors will have extended MEMORY longevity through Intel’s ACPP program. Higher speeds will be validated on this Up to 1GB using 100MHz SDRAM product when available. Call for current speed support. ECC Support PCI BUS PCI BUS The LBC8940 provides support for up to 4 - 32 bit PCI cards at 33MHz. Each of 33MHz - 32 bits these slots can be bus masters. The LBC8940 can fit into any PICMG designed backplane. BIOS DTI Enhanced PHOENIX BIOS, Plug-n-Play compliant ISA BUS The LBC8940 provides an interface to the ISA bus with DTI’s enhanced buffering to PCI Dual Channel IDE reduce loading issues that can occur with high slot count backplanes. EIDE support, DMA 33 ATA, bootable CD-ROM SYSTEM MONITOR PCI SCSI The LBC8940 includes DTI’s standard system monitor which provides SymBIOS SYM53C1010 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 fan/switch monitoring through eight inputs, a built-in two-stage watchdog timer, alarming DUAL PCI ETHERNET mechanisms for failure reporting, a dedicated serial port for remote communication 10/100 Base-T using Intel’s 82559 through a modem or a CPU-to-CPU connection, and a general purpose scratch pad area. AGP VIDEO with FLAT PANEL SUPPORT C&T 69030 with 4MB video memory AGP VIDEO The LBC8940 uses the C&T 69030 to provide enhanced graphics performance and USB flat panel support. Four megabytes of synchronous graphics memory is built into the UHCI compatible host controller with two ports 69030. FLASH DISK ETHERNET ISA Solid State Hard Drive up to 72MB The LBC8940 supports two auto-negotiating 10/100 Base-T connections, and full duplex operation which allows data rates to reach 20Mbps and 200Mbps. KEYBOARD/MOUSE PORTS External PS/2 keyboard and mouse connections. SCSI The LBC8940 provides a high performance Low Voltage Differential Ultra-II SCSI PHYSICAL interface allowing data transfers to reach 160 MB/s using the SymBIOS 4.2” x 13.3” SYM53C1010 LVD SCSI controller. A second independent SCSI channel supports older fast SCSI devices.
