The Pentium CPU has its standard on-chip cache memory (typically 16K). In addition, a 512K byte synchronous-burst secondary cache is provided to increase performance. The board uses a single DIMM memory module for main DRAM memory, and supports from 16M bytes to 256M bytes in a 64-bit configuration. Both EDO and SDRAM 3.3V DRAM types are supported. (5V DRAMS, ECC, and DRAM parity are not supported.) The module has a full complement of standard PCI PC/AT architectural features, including DMA chan

Little Board/P5x Technical Manual be stacked directly on top of the Little Board/P5x using its PC/104-Plus expansion bus interface as a rugged and reliable interconnect. The Little Board/P5x module’s on-board EIDE, video interfaces, and optional SCSI interface are internally connected to its PCI bus. In addition, you can attach PCI peripherals to the board’s stackable PCI bus expansion connector in much the same way PC/104 modules are stacked on the PC/104 connectors. The PCI expansion connector
