Barbara/Peter, Thanks for the information. When I went to school(NIU) in 2000 we designed a Student Operating system with the dispatcher running off the TCB chain. I recently went to Diagnostics class in z/OS and there I learned about the WEB.
I wonder if there is a Bible which explains everything about the OS concepts..not POO please. Steve, "Repressible or Exigent? Do you have VM or Flex-Es? Otherwise, it will be rather hard to force a real machine (or LPAR) to take/recognize an Exigent machine check. " I am not sure how they differ. I was just trying to understand it theoretically. >From ESPMIR, the only thing left is Restart and Machine check in a DISABLED mode, so I was wondering under what circumstaces Machine check is ever used or induced. Sorry for digressing from the original question.
