We have a new Motorola Delta 8864 system with dual 88k CPU running System V Release 3.2. We are trying to plug a Tadpole 1600x1200 color graphics card into it. The problem we are having is with a sequence of calls to shmget() and shmat(). Rather than delve into the many ways I have tried it that have failed, does anyone out there have a working code fragment they can send me that will: Grab a 20 Mbyte hunk of shared memory at a given physical memory location (the frame buffer and control registers) Attach to that shared memory and use it from user space. Thanks in advance. Allan Doyle adoyle@bbn.com BBN Systems and Technologies Corporation (617) 873-3398 70 Fawcett Street, Cambridge, MA 02138
