On most vintage computers hard drive settings page in the BIOS, you have to set the correct hard drive type from a list of pre-defined drive types. Most of the time when I try to enter in the settings, my hard drive type isn't listed and the heads, cylinders, megabytes, etc., on the hard drive don't match up with any on the list. For example, I'm trying to get a Seagate ST-157a to work in my Compaq Portable III. Is there a way to add custom entries to the list so the computer and hard drive can cooperate together? Or is there some type of software that can add a custom entry.
