3.2 Operational Environment
The LSI20160 is designed for use in PCI computer systems with a
standard bracket type. The SDMS software operates the board, but the
design of the board does not prevent the use of other software. An on-
board Flash memory device allows you to use BIOS code and open boot
code support through PCI and a serial EEPROM.
3.2.1 The PCI Interface
The PCI interface operates as a 32-bit DMA bus master. The connection
is made through edge connector J1, which provides connections on both
the front and back of the board. The signal definitions and pin numbers
conform to the PCI Local Bus Specification, Revision 2.2 standard. The
signal assignments appear in
Table 3.2 , Table 3.3 , and Table 3.4 .
Note: The LSI20160 uses 3.3 V pins to run the LSI53C1000 and
some other parts. The LSI20160 requires 3.3 V from the
PCI + 3.3 V power rail for proper operation.
