I just bought an new am3+ system. I decided on the asus sabertooth 990fx. This is my work pc so I need it to be really reliable. I started out by installing both xp and seven and used the windows seven boot loader. I had to set the drives to IDE to install xp. When I got to the boot loader, the keyboard wouldn't work. I couldn't do anything including press delete to go into bios. I was using a ps/2 keyboard so this seemed wierd. Finally I unplugged my razer deathadder and the keyboard worked. I went into the bios and disabled legacy usb support. Now it works with the mouse connected. Next I went to set a user password from the bios. Now whenever I turn it on it boots so fast it just skips the bios screen and goes strait to the password. I cannot enter the bios. If I reset cmos and disable the password, then the bios screen stays up long enough for me to enter it, but as soon as I set a password it goes to fast to press delete. I''m a little disappointed in asus. I've always been a big supporter in them. Anyone have any ideas what to do.
