The one thing I can think of is Appendix A of the General Information Man uals, IBM Processors Supported by VM. The GI manual for z/VM 4.2.0 is the last one to mention VM/ESA 2.3.0. See <http://publibz.boulder.ibm.com/epubs/pdf/hcsf8a50.pdf>. It shows support of processors up to the z900. (The only 'z' processor mentioned.) The z900 is supported by z/VM 2.3.0, but has caveats:
Notes on z900: For specific service levels required, contact your IBM representative. (1) 370-mode operating systems will not run as guests of VM on this ser ver. (2) VM230 does not support the CMOS Cryptographic Coprocessor. Moreover , APAR VM61244 is required to run this release on a machine with the CMOS Cryptographic Pro cessor installed. (3) VM230 requires APAR VM61762 to support IEEE Floating Point. (4) VM230 and VM240 do not support the z/Architecture (64-bit) capabili ties of the z900. The announcement letter for the z800 says it requires z/VM 2.4.0. So z900 is the official end of the line for z/VM 2.3.0. VM/ESA 2.3.0 may in fact run on the z800, but yo u aren't going to find anything from IBM that says so. If you are interested in earlier processors see the link above. Or perhap s even earlier versions of the GI manual. Alan Ackerman Alan (dot) Ackerman (at) Bank of America (dot) com
