Hi i have an Asus p5ne-e sli motherboard and i have just changed my Gtx275 for a Sapphire Hd5850 graphics card and it works fine with the 1406 bios except the motherboard will not see my wifi network card and i cant get the machine on the net now . i know people are having boot problems and have put 1903 beta bios in and it has helped , has anyone got any ideas or know how to get beta bios that is not posted on the website ? help appreciated
