The switch settings on the MX board should be 1-4 on, 5-6 off.
Switch #1 is the one closest to the outside.

However, this doesn't sound like your problem. EINVAL usual indicates
an unsupported ioctl.  There are some cases where read and write also
return it, and they all indicate some kind of blocksize mismatch.

Were the first and second tape files created in the same way, and can
they both be read on the originating machine?  Are you using the
fixed or variable block size device?  Can the first archive be read?
