We solved some installation problems–IRQ problems in a Pentium 90 with lots of cards: Monterey sound, Future Domain SCSi adapter. PAR, etc In case anyone has a similar problem—briefly: There are 4 ISA slots–old, standard, IRQs set on board. There are 4 PCI slots–new, IRQs assigned at the slot. The PCI BIOS is smart enough at boot time to allocate each slot to a free IRQ– but the NT driver for cards like the Future Domain are not smart and need a fixed IRQ. We assigned IRQ15 to the slot holding the controller card using BIOS set-up advanced features ssecti features section at boot time. (The Ethernet was re-assigned to IRQ11.) Another hint-make sure if youy are using a modem that it is turned on before you boot. The PCI bus assigns the otherwise free COM 2 IRQto something else, like the IDE PCI controller. With the modem turned on, the modem is recognised and nothing else is assigned. Otherwise you will show a conflict on COM 2, whcih can be confusing. So before you take out all those cards when installing NT, try this….. Chris
