Power5 9111-520 reload of AIX 6.1 - help needed

Hello all, I am hoping someone can point me in the right direction here.

We had a machine running AIX 6.1 that someone completely corrupted, so we decided to re-load it from media. I was able to boot into DVD media, select options for complete (destructive) install, AIX standard, etc. The installation seemed to go well. Toward the end I saw a failure screen flash by which seemed to indicate trouble loading file sets for various PCI and USB devices, however the installation seemed to complete and reboot the system.

When the system boots, the graphical console (vga and usb keyboard) only displays the textual AIX welcome screen and then appears to go unresponsive. I was expecting at some point to see the initial AIX setup. Service console and serial ports don't seem to respond to anything either.

There is some evidence that this machine was once configured to be managed by an HMC server ... but that server has gone defunct and not available at this time.

Any advice? I am open to just about anything ...

Thanks
