Thanks for the response... I'm using a Diamond Stealth video card ... so thats not it.
Nor is the port chip.

The reason I asked is because I get random dropped carriers under native dos and warp
and noticed under warp I get a sequence of about 3 or 4 of these errors  reported (the dos software doesnt say anything)
every time just before the carrier drop.
