The V56LA is a high-performance system board with a 64-bit
architecture. It supports the Intel P54C and P55C CPUs running at
100/120/133/150/166/200
MHz. It also supports 6x86/6x86L
Cyrix/IBM and AMD K5/K6 CPUs. The system board utilizes the
Peripheral Component Interconnect (PCI) local bus architecture that
maximizes the system performance by enabling high-speed
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. Two DRAM
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
cache.
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.
