Re: keyboard prob
That could be a solution. IRQ sharing is possible and devices work properly, but some devices are just so darn picky that they have to have their own IRQ's to work. Since IRQ sharing is not considered a ‘conflict’, your computer will not raise any red flags or yellow exclamation marks. No errors will occur, but your keyboard will still not work.
Have you tried using a PS/2 to USB adapter and just plugging it in to your USB port?
