SDRAM

Two SDRAM chips, soldered to the card, supply 32 Mbytes of synchronous, dynamic,
random-access memory. This SDRAM maps to the Intel
nSDCS0. For more information, refer to the Memory Controller chapter in the Intel
Processor Family Developer's Manual.

Flash Memory

32 Mbytes of the Intel StrataFlash
ROM (mapped to Intel
swapping an nCS0 signal to the flash memory bank on the main board, which then serves as the
boot ROM. For more information on using the Flash memory as the boot source, see
Note: The processor card's L18 flash memory always uses a 32-bit bus. Do not try to alter the bus width
with the setting of switch SW1.6. If an application requires a 16-bit boot bus, it must use the
