Bytes 30 to 45 of the CMOS are reserved for use by the user so
you can stick anything you like there. Use OS_Byte 162 to
store something in a byte, for example, in Basic you could
type:

        SYS "OS_Byte", 162, 40, 123

You can then read it back with OS_Byte 161:

        SYS "OS_Byte", 161, 40 TO , , X%
        PRINT X%

So store a known value in the CMOS, boot NetBSD, use reboot and
then check that the value stored is what you expect.
