Oh Wise Seers, I pulled this ancient Connor 170mb HD out of my old 486 machine. It was made around 1991, is a hoary looking thing with semi-cipherable jumper diagram, etc. But it gave me good service for 5+ years. And it ain't over yet (I hope). Mostly I just need to copy some data from it. I'm trying to install it in my socket 7 system with Tyan S1571 TX mobo. It failed to install as Primary slave, Secondary Master, etc. I can't get it to autodetect at all. None of the 40+ HD settings in my Award v4.51 pg bios _appeared_ to be correct. Quoting chapter and verse on the mnfgr's parameters (cyls, sectors, etc) didn't seem to help. Also set PIO down to 1 and 2: "nobody home". Hey, its just an IDE drive! My TX mobo supports IDE stuff circa '91, doesn't it? Doesn't it?? I figger its something silly, but I can't think of what. All suggestions welcome.
