Well, now for the good news! After talking with Debbie at Stallion's (makers of the BRUMBY card) technical support she directed me to the /etc/conf/pack.d/kernel/space.c file (which was replaced by the patch). In this file is a structure which defines the tty line disciplines (linesw) which installation of the BRUMBY device driver modifies by adding a fourth line discipline. Unfortunately, installation of the patch from ESIX replaces this file with one that no longer contains the necessary (for the BRUMBY card) line discipline. A simple manual edit of the new space.c file to include their two lines (they are both flagged with a comment containing the three characters "ATA") that had been in the old one and a rebuilding of the kernel has fixed the problem. Note that the patch appears to be working as it should (the test program now memory faults). -- Bob Willcox ...!{rutgers|ames}!cs.utexas.edu!romp!rancor!bob Phone: 512 258-4224
