=46rom the man page:
[...]
     This device is obsolete and is provided for compatibility purposes onl=
y;
     use i386_iopl(2) instead.
[...]
     The io file appeared in NetBSD 1.0 after it was in the kernel for some
     time.

This function call was depreciated and replaced with i386_iopl. Option_10 i=
s=20
only used to build kernels to be backwards compatible with old binaries.

=46or info on the current implementation read i386_iopl(2)
