Thanks Jim got me on the right path...
for some reason login from tty was disabled but that wasnt the only problem "clocal" was missing from the run modes.

To fix it i booted from CD in maintenace and created a script to change the settings
Code:
chdev  -l tty0 -P -a runmodes=hupcl,cread,brkint,icrnl,opost,tab3,onlcr,isig,icanon,echo,echoe,echok,echoctl,echoke,imaxbel,iexten,clocal 

chdev -l tty0 -P -a login=enable
i then added this script to inittab to run just before cron
i then rebooted the machine, if it didnt work the first time i rebooted again (hence the "-P")
it then gave me a shell prompt where i removed the script from inttab and rebooted again...
finally i have the install_assit start

I had tried to change the tty setting directly in maintenance mode but it failed, i think it is because the ODM in use is from the CD not the hardrive, i also tried using maintenance mode to mount the filesystems manaually and chrooting to my new / and changing the ODM but that didnt work either.... if anyone knows a easier way to do this it will be good to know but this works!

For info the machines in question are 7043-150's with system firmware TCP05287 so if you upgrade to this firmware as required to run AIX 5.3 on the machine this is what happens!
