System in Loop during Boot up

[redwings]

Hello All,

I am trying to reinstall AIX 4.3.3 on an 43P 150 server. The only issue is the server is in a continuous loop and restarts after a few minutes. It never gets to the log on screen before it reboots. I know there is a way to get into maintenance mode but I can not remember it. The only error message i get is 20E00008. Can anyone help me with this?

20E00008 is usually a bad battery or bad system board....

Getting into service mode is the

When booting a PowerPC into Service mode, cd0 or rmt0 must be before
the hdisk in the bootlist. If not, change the bootlist at boot time. On
some models, you can set the machine to use a default bootlist
that includes both cd0 and rmt0. If a bootable CD or tape is in
the CD-ROM or tape drive, the machine will boot from this device.

For most of the newer PCI-based models, selecting the default bootlist,
with a bootable tape or CD loaded in the machine, causes the
system to automatically boot from that device. Generally, the next
menu on the screen asks the administrator to define the system console.
On these machines, use 5 (on the keyboard, not the keypad) if you
are using an ASCII terminal. On a locally attached
graphics console, use the F5 function key. The F5 or 5 key must be
pressed just after the keyboard icon or message is
displayed on the console. If you have either a 7026-M80,
7026-H80 or a 7025-F80, then the 5 key will be the default
whether you have an ascii or graphics console.
