I am running a Dell Desktop, with Win 2000, and the A09 revision of the BIOS. I have had a it running perfectly with 2 cd drives and one harddrive set to master, with the secondary hard drive set to off in the BIOS. I just put another hard drive in, and it causes the computer to boot via MBA. I have tried the jumper settings (http://www.maxtor.com/_files/maxtor/en_us/documentation/jumper_settings/style_a1.htm
) , but I cant set the secondary one to slave because there is a little piece of plastic covering the upper right pin. Any ideas?
