Some time ago (after the release of Ultrix 2.0) there was a discussion here about how to upgrade drivers written under 1.2. Could someone post a summary of the conclusions reached at that time? Also, I probably will go straight from 1.2 to 2.2. Does anyone have any experience porting drivers to 2.2? Thanks a lot.

We are in the middle of moving from 1.2 to 2.2 (we have extra disk space). We also run UREP. At the same tiem that we are doing the ULTRIX upgrade we are upgrading from UREP 2.0 to 3.2. If you find anything out, I would like a copy. I just joined the list recently. From the people I talked to, they said don't go from 1.2 to 2.0 (this was two months ago) because going from 2.0 to 2.2 is as difficult as going from 1.2 to 2.2. Talk to Mike Petry if you want the specific information. Jonathan

I sent this info to Dave so it may already be somewhere with the 3.2 distribution.... You simply remove the local declaration of "register int br,cvec" in the dupprobe() routine. Br and cvec are now global variables rather than a magic trick as in 4BSD (assembler code that "knows" that the C compiler allocates particular registers in a particular order for register ints).
