5.1
CPU
Intel
Pentium
Processor with MMX
Technology on 0.25 Micron (HL-PBGA-
package) 266 MHz.
5.2
Chipset
The
cool
MONSTER/S
board operates with the Pentium chipset Ali Aladdin V AGPset, which consists
of the M1541 (north bridge) and M1543C-B1 (south bridge). Older versions of this board may as
well be equipped with the M1542 (north bridge) and the M1543C-A1 (south bridge). The chipset
provides the following features:
North Bridge M1541
Pipelined-burst SRAM/Memory cache
SDRAM DRAMs
Synchronous/pseudo synchronous 3.3V/5V tolerance PCI interface
Enhanced power management
Accelerated graphics port (AGP) interface
South Bridge M1543C:
PCI 3.3V/5V tolerance interface
Buffers control
Provides steerable PCI interrupts for PCI device Plug-and-Play
Enhanced DMA controller
Interrupt controller
Counters/timers
Distributed DMA supported
Serialized IRQ supported
Plug-and-Play supported
Built-in keyboard controller
Positive/subtractive decode for ISA device
PMU features
Built-in PCI IDE controller
USB interface
Super I/O controller for two serial interfaces, parallel and floppy drive interfaces
5.3
Super I/O
An additional SMsC FDC37C669 offers two more serial interfaces (COM C and COM D). The I/O port
addresses of these two more serial interfaces are mirrored every 800hex because the address
decoding here is only done with the address lines SA0 to SA10.
