LINK Version 5.01.21 does not support the combination of using the
/PACKCODE switch and having code segments declared as IOPL (i.e., as
having I/O privilege).

When combining segments as directed by the /PACKCODE option, LINK
5.01.21 will combine the IOPL segment(s) with other segments that do
not have I/O privilege. The result is an invalid executable that
returns the system error SYS1059 when it is invoked.

The lack of ability to combine these options is a limitation of this
particular linker version. LINK Version 5.03 allows the combination of
/PACKCODE and IOPL segments without a problem.
