Signal Description
Copyright © 2004, 2005 by LSI Logic Corporation. All rights reserved.
MAD[31] NVSRAM or SRAM Installed – Pulling this signal HIGH
indicates that an NVSRAM or an SRAM is installed. Pulling this signal
LOW indicates that neither an NVSRAM nor an SRAM is installed.
MAD[30] NVSRAM or SRAM Select – Pulling this signal LOW when
MAD[31] is pulled HIGH indicates that an SRAM is installed. Pulling
this signal HIGH when MAD[31] is pulled HIGH indicates that an
NVSRAM is installed.
MAD[29:17] – Reserved.
MAD[16], PCI-X Operation – Pulling this signal LOW enables the
PCI-X operation. Pulling this signal HIGH disables PCI-X operation.
