I installed a NEC USB 2.0 PCI card. Now my Sound Blaster Creative SB16\nEmulation does not have an IRQ to use. Would have to remove another\ncomponet to use. Also bought a Promise Sata150 TX2plus to try and\nbring my system up to technology but will not find my WD 136aa Hard\ndrive. I have tried differant slots and differant jumpers to no\navail.What compliency is pci slots on my motherboard. sata 150 needs\nPCI to be 2.2 or 2.3 compliant. Please help me.
