Hello, I am seeing something similar when trying to IPL the install kernel on a 31 bit platform. I have punched the files to the reader in this order: kernel.img, redhat.parm,initrd.img. The machine has 160Mb of memory assigned to it, and the error that I am seeing when I try to IPL is : UNI27VL: HCPVMJ232E IPL UNITY ERROR; IRB 01404417 00000010 00204040 00800000 UNI27VL: HCPGIR450W CP entered; disabled wait PSW 00E0000 00000232 Any ideas for what I could be doing wrong ? Thanks in advance, Ryan
