OT? Help with Compaq Deskpro 486-33L

I am helping a friend add a CDROM to his Compaq system. It has is an IDE cable but the driver that came with the CDROM does not recognize the drive. I suspect the IDE address and/or IRQ may not have been standard at that time. Does anyone have the tech specs on this compaq system? I've checked the Compaq support site and though there is some info it is not terribly helpful.
