User's Manual 5
HOT-541 mainboard is a highly integrated IBM PC/AT compatible system
board. The design will accept Pentium processors operating in 75MHz,
90MHz, 100MHz, 120MHz, and 133MHz, and also features high-perfor-
mance asynchronous and pipelined burst secondary cache memory support
with size of 256KB and 512KB. The memory subsystem is designed to sup-
port up to 128 MB of EDO RAM or standard Fast Page DRAM in standard 72-
pin SIMM socket. A type 5 or type 7 Pentium CPU socket provides access to
future processor enhancements.
HOT-541 provides a new level of I/O integration. Intel's T-Chip 82430 PCISet
chip set provides increased integration and improved performance over other
chip set designs. The T-Chip chipset provides an integrated Bus Mastering
IDE controller with two high performance IDE interfaces for up to four IDE
devices.
The SMC Super I/O controller provides the standard PC I/O functions: floppy
interface, two FIFO serial ports, one SPP/EPP/ECP capable parallel port.
Up to four PCI local bus slots provide a high bandwidth data path for data-
movement intensive functions such as graphics, and up to four ISA slots com-
plete the I/O function.
The HOT-541 provides the foundation for cost effective, high performance,
highly expandable platforms, which deliver the latest in Pentium processor
and I/O standard
