I am not sure. the 0x8c09 is possibly used on mobile PC not desktop. On one of my machine, it includes the chipset but the 2 ports IDE controller is not extend out for use. There are only 2 ports extended out from 4 ports IDE controller. So I can not verify it. I think, the notebook/mobile PC does not require to extends out all of the IDE ports. This patch only fixs the 0x8c08 2 ports IDE controller for it block the installation. If there is an issue reporting from 0x8c09, we can fix it late. Thanks -Youuquan
