Hello aopen users! I have a Aopen Ak77-8xn board. I used to run bios r1.13 and updated to the recently released r1.15. After rebboting the windows 2000 boot process starts and gives me a "inaccessible boot device" error and refuses to go further. Here comes the panic! I flash the bios back to the r1.13 After hours of trying this and that i finaly went to the emergency console on my Windows 2000 Pro install CD. And running chkdsk c: /p /r fixes this issue. My system funktions as normal again with the old bios r1.13 Is there a serious bug with release 1.15? Have any other had this problem? Anders
