Any suggestions? We don't allow sharing of EISA irqs yet, so they must be different. Hmmm. I don't have any suggestions of the top of my head. I've run multiple aic7xxx based controllers in machines before (my home machine has two of them) and I've not seen this type of problem. Its sounds almost like an IRQ conflict. >============================================= >Matt Rosenberg >Washington University School of Law >St. Louis, MO, USA > >mar7@cec.wustl.edu ; rosenbem@wulaw.wustl.edu >http://www.cec.wustl.edu/~mar7/ >============================================= > > > -- Justin T.
