z/VM 6.1 under Hercules - How To

To All,
    For the group. Basically you have to set a Breakpoint in Hercules, modify VM storage and continue the IPL. I strongly suggest you use the Hercules CMD Prompt window, not the Hercules GUI. If you're using the z/VM 6.1 Base system, follow/use the "Base" values below. If you apply the z/VM 6.1 RSU, then use the values on the left side.
 
Once a new RSU comes out, it may modify storage locations again and a new Hercules Trace will have to be done (see below).

IPL (from Hercules CMD prompt window)

1. hercules -f c:\hercules\zvm610\hercules.txt            (change to your Hercules config file location)
2. B+ 2AAF98                                  (z/VM 6.1.0 Base: 2AA998)
3. IPLC 340D                                   (replace address with your IPL address)
4. GPR                                              (R2=002F4108) (z/VM 6.1.0 Base: R2=002F3008)
5. R 2F4108                                      (z/VM 6.1.0 Base: R 2F3008 ---> xxxxxxxx F0700000)
6. R 2F410C=F0FF0000                   (z/VM 6.1.0 Base: R 2F300C=F0FF0000)
7. (press ENTER)
   (IPL should complete normally)
8. CMDTGT SCP                              (sends commands to z/VM)
8.5 ENABLE ALL                              (enable all VM 3270 terminals)
...have fun...
9. HERC CMDTGT HERC                (sends commands back to Hercules)
10. QUIT                                          (exit hercules)
