Intel Server Board N440BX

Intel Server Board N440BX ... require the board's 82440BX chipset, which supports their 100MHz system bus speed--an increase of 50% over the older system bus speed of 66MHz. Upgrading to an 82440BX system isn't just a matter of utilizing faster CPU's; data flow is sped up between the processor and each component in the system.

The N440BX board contains four 168-pin gold-plated SDRAM DIMM sockets which support up to 512MB unbuffered or 1GB registered PC/100 100MHz SDRAM. Accepted memory module sizes are 32MB, 64MB, 128MB and 256MB (registered). Either 72-bit ECC or 64-bit non-ECC 3.3v memory is supported. Five expansion slots are available on the board: three dedicated PCI slots, one dedicated ISA slot, and one PCI/ISA shared slot. The Intel PCI/ISA/IDE Xcelerator (PIIX4E) supports up to four IDE devices, DMA controllers, two fast IDE interfaces, a multi-function PCI-to-ISA bridge, power management logic, and a real-time clock. The National Semiconductor Super I/O controller integrates the standard I/O functions such as floppy drive interface, two Asynch serial ports, and keyboard and mouse controllers. Many important server components are integrated onto the board, including Intel's EtherExpress Pro+ 10/100MB network adapter, a Symbios Logic Dual Channel 40 MB/sec Ultra-Wide SCSI controller, and a Cirrus Logic graphics controller with 2MB of SGRAM. The N440BX motherboard has a Server-AT form factor, measuring 12in. x 13in., and fits in most ATX 2.0 compliant tower chassis.
