Description Duane Beyer 2003-10-09 17:55:32 UTC
The following has be reported by IBM LTC:  
Cannot determind  if PFIX support  on or off with 64 bit systems.
Hardware Environment:z/900

Software Environment:RHEL-3 RC1


Steps to Reproduce:
1.When running Linux as a VM Guest,  add OPTION DIAG98 in the VM directory for 
the guest.
2.IPL the REDHAT RHEL3 Guest

Actual Results:  System IPL's but there is not message stating if PFIX is 
supported or not.

Expected Results: On a 31 bit system get the following:
     With Diag98 option the following appeared on the console. 
	This machine has PFIX support
     Without Diag98 set got the following message:
	This machine has no PFIX support 


Additional Information:  Need to be able to Determind on a 64 bit system if 
PFIX support is on or off on 64 bit systems.
