The AcerPower 4100 system board is a high-performance all-in-one system board with LPX
form factor. It supports the Intel Pentium II processors with speeds ranging from 233 MHz
to 450 MHz. The Pentium II comes in a card design with 256- or 512-KB second-level cache
already integrated.
The system board has three 168-pin DIMM (Double In-line Memory Module) sockets that
accept PC-66 or PC-100 DIMMs with 16-, 32-, 64- and 128-MB capacities, with or without
ECC (Error Correction Coding) feature. The system memory is upgradable to 384 MB.
The board also incorporates a 3-D video controller with AGP (Accelerated Graphics Port), 4-
MB SGRAM (Synchronous Graphics Random Access Memory), a 3-D ISA audio controller, a
10/100Base-TX Ethernet controller, and an AOL (Alert-on LAN) chip.
Onboard I/O (input/output) interfaces are comprised of a UART (Universal Asynchronous
Receiver-Transmitter) 16C550 serial port, a parallel port with SPP (Standard Parallel
Port)/ECP (Extended Capabilities Port)/EPP (Enhanced Parallel Port), and PS/2 keyboard
and mouse ports. Two USB (Universal Serial Bus) interfaces, one VGA (Video Graphics
Accelerator) port, and one audio connector for AIO board are also added to the system design
to enable it to support multimedia functions. For expansion, the board comes with one riser
card that supports three PCI and four ISA (shared) slots.
Special features such as ACPI (Advanced Configuration and Power Management Interface)
support, PnP (Plug-and-Play) support, APM (Advanced Power Management), Wireless
Communication, Hardware Monitoring, Modem Ring-in, Wake-on LAN (Local Area
Network), and Alert-on LAN functions are also supported. These functions are individually
discussed in this chapter.
The system is fully compatible with MS-DOS V6.X, OS/2, SCO UNIX, Windows NT, and
Windows 95/98 operating systems.
