To operate the DE1B55503, the following equipment is needed:

•

A computer system equipped with PCI option slots.

•

A PCI expansion slot on the motherboard that is equipped for the 5V PCI environment.

•

The DE1B55503 kit provides DOS utilities that can be used to configure the program in the SROM 
and parallel ROM. The diskettes included in the DE1B55503 kit contain:

•

PVIEW.EXE to read all PCI configuration space registers.

•

CDEBUG, a version of DOS DEBUG that reads memory locations directly. 

•

DOS4GW.EXE is a DOS32 extender. It must be in the same directory when running the 
utilities.

•

DBFLASH.EXE an executable utility for erasing and updating the flash ROM memory.
