Thanks Ron, I have the integrated ascii console working now.

The mingetty line comes commented out. # # z900 LPAR SE/HMC VT220/Linux console - uncomment to enable getty on it: # 2:2345:respawn:/sbin/mingetty --noclear /dev/ttyS1 linux Then once you have done a telinitq or rebooted and gotten all the way up. You click on ASCII Console instead of operating system messages. You get a blank screen. Then position you cursor on the screen and press enter. You should get a login prompt.
