Interesting error message when you try to run 2DiskWin (which requires a 486) on a 386:
"Checking if this processor honours the WP bit even in supervisor mode... No.
Kernel panic: This kernel doesn't support CPU's with broken WP" - This error is regarding write protection on kernels

"The "bug" is really the lack of a feature present on 486+ cpus. A 386
will allow the kernel to write to a write-protected user page (but not a
write-protected kernel page). In user mode, write protect works as it
should. The kernel works around this by doing extra checks when writing
to user pages (check the *_user() functions). It is not a security
hole, because if the kernel wasn't compiled with the workaround, it
refuses to boot on those cpus."
