After installing a second XP on my computer (on seperate hard drive) I cannot identify what drivers I need to install for some devices listed in Device Manager. They are the following: - Other PCI Bridge Device (Only have sound card installed in PCI slot) - PCI Input Device I know my motherboard in effect has two BIOS's because theres an added Sis chipset which adds SATA and a LAN port, but I'm sure I installed the drivers for them (the extra SATA and lAN run off the PCI bus according to my mboard manual.) I have a ECS KN1 Extreme motherboard. I have installed the following drivers: 1) Monitor 2) CPU 3) G.Card 4) Sound Card 5) Chipset (nForce 4ULTRA) 6) The drivers which I THINK are for the added SATA and LAN ports system specs: ECS KN1 Extreme Mobo (with added Sis chipset) 3800+ AMD 64 200GB Seagate, 80Gb Samsung (SATA through nForce) X850XT PE Audigy 2ZS 1GB ram can anyone think of any other drivers/what the hardware is? I keep looking through the disk I got with my motherboard but I seem to have installed everything needed (obviously not though) Thanks for any help!
