Adaptec 154x cards didn't work in the first Zenith 386/16 machines, because of a bug in our bus mastering hardware. This bug was fixed in later versions of the Z386/16. (Adaptec's DMA test will fail on these early Z386/16s.) The Adaptec 154x cards are tested on all Zenith 386 designs, and are known to work, with the single exception noted above. > ken seefried iii ken@dali.cc.gatech.edu Brad Staff Zenith Data Systems Systems Software Engineering 150 Hilltop Road St. Joseph, MI 49085 bjstaff@zds-ux.zds.com
