I have a Zenith GT-166 running NT Workstation 4.0. I have an Intel EtherExpress 82557 PCI-Based 10/100 ethernet card which is at IRQ 11, which works fine by itself. However, when I add an Colorado System SC 50 SCSI card (really an Adaptec 15xx (AIC 6x60)), on which I've set the jumper to IRQ 10, NT loads the sparrow.sys driver at IRQ 11 instead of at IRQ 10 (there's also an I/O conflict at 140-15F). How can I get the sparrow.sys driver to recognize that there's already a device at IRQ 11? I've noticed that running the NT diagnostics program and looking at resources/IRQs only shows the ISA resources and IRQ 11 appears free, so somehow I need to make the system aware that IRQ 11 is already taken. Thanks!
