You are giving up valuable lower memory by using DOS TSR programs (probably
about 70-80k).  This exacerbates the Windows-DOS conflict.  You are also
consuming a valuable DOS IRQ along with a shared RAM memory address.  Any
one of these conflicts can cause the problem you describe and/or other
problems.  

I think it is worthwhile to utilize the Synapse (www.synapse.com) twinax
adapter that eliminates conflicts due to its onboard microprocessor based
design, onboard RAM, and double buss buffering.  It uses no IRQ, no shared
RAM, no DOS TSR's, and no DMA.

As a byproduct it transfers data twice as fast as IBM/Clone like IO.  You
can use their software or any favorite you might choose.

Synapse has the only twinax card that runs perfectly in high speed pentiums
with no line drop off or freeze ups.
