I have run drives with 8 and 11 heads with no problem whatsoever, on both the 2090, and the 2090A. Currently I am running a 3.5" Maxtor LXT100 wirh 8 surfaces, and a Micropolis 1355 ESDI drive with 8 surfaces on the 2090A with it's ROMs removed. No problems with either one. -larry -- " All I ask of my body is that it carry around my head." - Thomas Alva Edison - +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+
