I flashed my bios to the latest (F12) for my Gigabyte GA-965P-DS3 (rev. 3.3) motherboard http://www.gigabyte.com.tw/Products/Motherboard/Products_Overview.aspx?ProductID=2456 Unfortunately, there has been no change to the situation. The same ioport ranges are being reserved when booting with 2.6.24-rc4 and it87 does not work. No change to the situation in 2.6.23.9 either, the io conflict is not occuring and it87 still works there. Mike Houston
