(Tom Limoncelli -- TLimonce@Drew.Bitnet) We encounted this the first night we installed Minix (about a year ago). Yes, there are clone AT's with XT controllers in them. In this situation the "xt_wini" driver works fine. But, you must disable the "if (pc_at)" check in kernel/main.c, and force the "set_vec(XT_WINI_VECTOR, wini_int, base_click)". We did this with a flag on our kernel make file: "make wini=xt" (or "make wini=at"). We will be pleased to help those people who know that this is a problem with their hard drive configuration. -------------------------------------------------------------------- Edwin L.
