Am I just very lucky, or > what? The 3c509b and c can operate in one of two modes, pnp and non-pnp. My guess is that they were configured for PNP operation and you have a bios that handles pnp better than the pnp bios in 486's and older pentiums. When Plug and Play was first introduced, there was a reason why it was coined Plug and Pray. Nowdays, PNP pretty much works as advertised (at least on Intel and Via chipsets.) The other issue at play here is trying to get two 3c509's into one box. It will work, but you'll usually have to tweak a bit (espically true for older machines.) -- Andy Zbikowski, Sys Admin | (WEB) http://www.ltiflex.com LTI Flexible Products, Inc. | (PH) 763-428-9119 (EX) 132 21801 Industrial Blvd | (FX) 763-428-9126 Rogers, MN 55374 | (PCS) 612-306-6055 -------------- next part -------------- A non-text attachment was scrubbed...
