Acer V55LA-2 Manuals

&KDSWHU  System Board System Board 1-1 The V55LA-2 is a high-performance system board with a 64-bit architecture. It supports the Intel P54C and P55C CPUs running at 75/90/100/120/133/150/166/200 MHz. It also supports Cyrix M1/M2 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. The board incorporates a Sound Blaster Pro-compatible audio subsystem that consists of CD-audio, WaveTable, and fax/modem line-in interfaces. A standard 1-MB video DRAM comes onboard and is upgradable up to 2 MB. 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 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.
