Installing FreeBSD -> Fatal trap 12

[nicholaserho]

Hello, I am trying to install FreeBSD from floppies on a 486-DX-33, and with
the three floppies I made I cant get to the boot menu screen (with the devil)
but if I attempt to boot I get a "Fatal trap 12: page fault while in kernal
mode" error. The same error happens if I try safe mode except my system
restart. What can I do to fix this so I can install FreeBSD?

Exact Error Message:

Any advice that you could give me would be welcome. Thank you for your time.
