Hello, I have read lots of help that requires using a keyboard but I can't make it work. I have tried connecting a PS2 keyboard to the press using one of the PS2 ports on the back of the tower hidden under the console. It works in as far as I can use the DEL key to get into the BIOS setup (which is password protected) but I cannot make Alt-X or any other combination of keys work after a normal boot. What am I doing wrong to get into DOS? Maybe the keyboard disabled in the BIOS? If so what is likely to be the password to go in and change that?
