This allows us to successfully attach early Storage Dimension cards. Allocate mailboxes for the 742A bellow the 16MB limit. Although these cards seem to be able to deal with all other types of data anywhere in a 32bit address space, 24bit addresses are required for mailboxes. bt_eisa.c: Add device IDs for all Storage Dimension products I could find from their web site. Thanks to Ted Mittelstaed for loaning me the equipment to diagnose and fix these problems.
