Microprocessor

– The VMIVME-7740 brings the Intel Pentium III processor to VMEbus.

The VMIVME-7740 introduces the Intel Pentium III processor to the VMEbus with processor speeds up to 850 MHz. the Pentium III processor has 32-bit addressing and a 64-bit data bus.

Its superscalar architecture allows three instructions per clock cycle. Dynamic branch prediction units, separate instruction and data caches, and MMX™ technology also increase processor performance.

The Pentium III processor also offers a 256 Kbyte Advanced Transfer Cache (on-chip, full-speed L2 cache) with dual independent bus architecture dcs-sis.com for high bandwidth and performance.

This L2 cache is clocked at the same frequency as the processor, which improves performance.

Memory

– The VMIVME-7740 accepts a 144-pin SDRAM SODIMM with a maximum memory capacity of 512 Mbyte.

The maximum memory capacity is 512 Mbyte. on-board DRAM is dual-ported to the VME bus.

BIOS

– The system and video BIOS is provided by reprogrammable flash memory.

Super VGA Controller

– High Resolution

The VMIVME-7740 supports high-resolution graphics and multimedia-quality video through the Chips & Technology AGP graphics adapter.

The adapter is complemented by 4 Mbyte of internal high-bandwidth 64-bit data interface synchronous DRAM.

The graphics adapter supports screen resolutions up to 1.600 x 1.200 x 64.000 colors (single view mode).

Ethernet Controller – The VMIVME-7740 supports Ethernet LAN through dual Intel 82559 Ethernet controllers.

Supports 10BaseT and 100BaseTX options through two RJ45 connectors. Remote LAN booting is supported.

Remote Ethernet Booting – The VMIVME-7740 utilizes Lanworks Technologies, Inc. BootWare to provide the ability to remotely boot the VMIVME-7740 using NetWare, TCP/IP, or RPL network protocols.

BootWare Features:

– Support for NetWare, TCP/IP, RPL network protocols

– Unrivaled boot sector virus protection

– Detailed boot configuration screens

– Comprehensive diagnostic capabilities

– Option to disable local boot

– Dual boot option allows user to select either network or local boot

Serial Ports – The VMIVME-7740 has two 16550-compatible serial ports on the front panel. The serial channel has a 16-byte FIFO and supports baud rates up to 56 kilobytes per second.

56 kilobytes per second. Two micro-DB9 to standard DB-9 adapters (VMIC P/N 360-010050-001) are required.

Keyboard and Mouse Interface – The VMIVME-7740 is equipped with a PS/2 combo keyboard and mouse interface. A Y adapter cable is included.

Flash Memory – The VMIVME-7740 provides up to 192 Mbytes of IDE CompactFlash flash memory, accessible through the auxiliary IDE port.The VMIVME-7740 BIOS includes an option to allow the board to boot from flash memory.

16-Bit Timers – The VMIVME-7740 provides the user with three 82C54-compatible 16-bit timers (in addition to the system timer). These timers are mapped to I/O space and are fully programmable by software.

Watchdog Timer – The VMIVME-7740 provides a software programmable watchdog timer.

The watchdog timer is enabled under software control. Once the watchdog timer is enabled, the on-board software must access the timer within the specified timer period or a timeout will occur. A user jumper allows the timeout to cause a reset.

Independent of the jumper, software can enable a watchdog timeout to cause a non-maskable interrupt (NMI) or VMEbus SYSFAIL.
