The V56LA is a high-performance system board with a 64-bit
architecture. It supports the Intel P54C and P55C CPUs running at
Cyrix/IBM and AMD K5/K6 CPUs.
The system board utilizes the
Peripheral Component Interconnect (PCI) local bus architecture that
peripherals to match the speed of the microprocessor with its 120 MB
or 132 MB per second transfer rate in burst mode.
A 1-MB or 2-MB SGRAM comes mounted onboard.
banks composed of four 72-pin sockets come with the board to
support single- and double-density SIMMs for a maximum system
memory of 128 MB.
The SIMM sockets accommodate both the
standard page mode and extended data output (EDO) type SIMMs.
The board supports a 256-KB or 512-KB pipeline burst second-level
The system board includes a 188-pin connector for the slot board that
contains the PCI and ISA bus slots. The two onboard PCI-enhanced
IDE interfaces with a zero-wait state and 16.6 MB per second transfer
rate support up to four IDE devices. Onboard I/O interfaces comprise
of two UART 16550 serial ports, a parallel port with ECP/EPP feature,
and PS/2 keyboard and mouse ports.
As added enhancements, the board also incorporates a Sound Blaster
Pro-compatible audio subsystem plus plug-and-play (PnP), power
management, and software shutdown features.
