Fresh install of OSR2, Intel pro 10 PCI NIC card is conflicting with "IRQ Holder for PCI Steering"  on IRQ 11.  The fimware for the NIC does not allow one to change the pre-set IRQ of the NIC.  I have tried moving the card to a different PCI Bus slot to no avail.  It seems the Holder device "wants" to conflict.  I am using the latest driver for the NIC.

Please give us the details of your system, i.e. hardware installed. Have you tried changing the IRQ of the PCI Steering Holder that is conflicting? Try going into CMOS and if you have the option, assign IRQ to pci VGA, turn it on. Remove the card from the system and take a look at what resource is trying to use IRQ 11. It may say PCI Steering, but it could be your video card. See if you can change the IRQ of that particular resource. Let me know what happens.

Video card is ATI Mach64 (I know, bad choice, but not my decision. Video works none the less).  Device manager, showing IRQs, says that 11 is being used by the NIC and its steering partner.  I don't think the BIOS supports this function of 0SR2 or `98.  I need to suppress PCI bus steering, it is happening on two systems using this type of NIC card.  There is also a SB64 and 4x CD-ROM.  VX chipset I believe.  I have not pulled the ROM and sound card yet.  I do not have the problem when using a 3Com NIC.  I appreciate your time.  Paul

1) Was the NIC in the computer when you re-installed Windows?
2) Did you do a "fresh" install to a clean hard drive, or run setup over the previous installation?
3) Have you tried to remove the IRQ holders listed under system devices in Device Manager?
Windows should re-detect & install them again at startup.
