The Program New PSW has been modified to merely point at the instruction following the OI, so the AFP bit is left alone (it ought to check that CP IEEE support is also functional if no program check occurs and it is in a virtual machine and, if so, skip the machine_flags change and reset the AFP bit in CR0, but since I'm probably the only person in the world that would care, I'll just zap the bit). Unless, of course, CP will panic when it sees the funny program check caused by attempting EFPC with the real AFP bit off.

Re: Encryption on a 7060
There are not many holes, but things to consider. We had a MP3000 H30 also. 1. It doesn't perform Linux stuff as well as other mainframes. There is a CPU instruction added in newer systems, that made Linux performance much better. So, don't take poor performance on the MP3000 as an indication of performance on new boxes. But if you lave the CPU time available, it works. 2. You have to run SLES 7 or SLES8 (in 31 bit mode). As these are older distros, they may run out of support. That may affect how auditors view the setup. 3. As 31 bit code disappears, you may not be able to keep up with the Jones with respect on where you are sending the files. I don't know how backleveled encryption software goes. You might be limited to 128 bit encryption instead of 2k encryption keys. 4. I have a GPG server which encripts files for our VSE systems.
