On an install and also on a normal boot, a system with a P202 monitor hangs at LED c31.
This is a problem with the 120p graphics adapter and the P202 monitor (at AIX Version 4.2.1). When the system boots from NIM (or disk or media), the LED c31 appears, but nothing appears on the console.
The workaround is to turn the monitor off and on. The long-term solution is to install IX82645.
There is a similar problem for 4.3, but there is no APAR yet.
For NIM installs, make sure the fix is in the SPOT.
