hey thanks, im readiing through those forum topics, and they are very helpful at explaining the reason behind my error code 10. seems that its all in the motherboard bios/apci/windows irq assignments. i just have to tinker until i find the right combination for my pci hardware in the pci slots. they also reccomend safemode - removing all hidden hardware & drivers. any other advice, how do i cure an error code 10, device cannot start?
