The V12LC is a high-performance Pentium PCI-based system board
that supports the 64-bit Pentium microprocessor running at
75/90/100/120/133/150 MHz and has a 16-KB internal write-back
cache. It utilizes the Peripheral Component Interconnect (PCI) local
bus architecture. The PCI local bus 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.
The system board features a slot for the PCI/ISA slot board and two
PCI enhanced IDE interfaces with a zero-wait state 11 MB per second
transfer rate and support up to four IDE devices. It has buffered serial
ports that reduce the number of interrupts to avoid slowing other
system activities. With the optional ECP/EPP function, the parallel
port transfers data at a fast 2 MB to 10 MB.
The system board has two DRAM banks composed of four 72-pin
sockets that support both single- and double-density SIMMs for a
maximum memory of 128 MB.
