Bob,
When you boot up, do whatever you have to do to get into Bios setup - hitting the DEL key during the boot is common. Sometimes the invitation flashes by, so you may have to be pretty quick.
Navigate to "Auto detect hard disks" (or words to that effect).
That should tell you what is on primary and secondary and which is master/slave, etc.
Once you have the info, ESC your way out and QUIT without saving.
HTH
