NOS_1229 packet driver help, please!

[Jim De Arras <jmd@banana.handheld.com>]

Folks,
I've just compiled GRINOS 1.8b, and all worked ok EXCEPT my attempt
to increase the number of packet drivers supported from 3 to 5.  I changed the
number in pktdrvr.h from 3 to 5, and all seemd to go well, but within seconds
of attaching the 4th packet driver, NOS causes a DV exception error, trying
to access memory outside of it's own area, actually somewhere in my Btrieve
TSR.  It doesn't matter which driver is fourth, so I don't believe it's the
dirver's fault.

Any ideas?  What am I doing wrong?
Thnaks,
