The Dell Precision 610 mini tower systems offer advanced expansion sub- systems that can support a mixture of traditional ISA expansion cards (called legacy cards), Plug and Play ISA expansion cards, PCI expansion cards, and a 2X AGP card. The operating system or the ISA Configuration Utility (ICU), included with the system, provides a means of avoiding resource conflicts that might arise from such an arrangement.
