None It is a hardware incompatibility

Re: Question Compact Flash Hangs old Laptop (Rui-Tao Dong)

This is a hardware issue with the NEC Versa and there is no possible
software workaround.

I have an old Versa and had a similar problem.  The issue is that the
Versa has an old PCMCIA bridge chip that conforms to an old version of
the PCMCIA standard (version 1.0).  Later standards redefined two pins
on the PCMCIA connector in a way that makes newer PCMCIA cards wedge
the older Versa hardware.

There is a hardware workaround but I don't recommend it and don't even
remember exactly how to do it.  You can open up the laptop and cut the
wire going to pin 43 on the PCMCIA connector.  I did this on my laptop
to enable one socket to work with the newer cards.
