... Here's a stickey one. I've just brought up unix on Compupro hardware with a 68k cpu using the 68451 mm. This system is not currently configurable and I need to be able to do port i/o to a foriegn board in the system. The cpu card maps memory requests to the top 64k to the i/o ports - so you have to be able to address absolute memory - which the memory management forbids. Got any ideas? What about /dev/mem or /dev/kmem? Also, I'd like to get a driver for my Sugart 4008's ready in anticipation of the reconfig files. I've got low level code written in c, but not in device driver form. I've no idea what a driver's supposed to look like - no doc on how to write one. Where do you get this kind of information? Is there any such thing as standard skeleton driver code to use as a starting point? Pleas reply with mail to ===> ihnp4!wlcrjs!stuey - Stu
