Hi all,
I'm looking to cover a corner case for an upcoming test cycle. Is there a way to boot a RedHat Advanced Server 4 (update 3) installed on a Power PC machine to use a 32 bit kernel? This would be similar to what is done here -> https://www.unix.com/aix/26204-aix-platform.html

pextrem
PEXTREM(1) General Commands Manual PEXTREM(1)
NAME
pextrem - find minimum and maximum values in RADIANCE picture
SYNOPSIS
pextrem [ -o ] [ picture ]
DESCRIPTION
Pextrem locates the minimum and maximum values for the input picture, and prints their pixel locations and color values. The first line
printed contains the x and y pixel location (x measured from the left margin, y measured from the bottom), followed by the red, green and
blue values. The second line printed contains the same information for the maximum value.
The -o option prints the original (radiance) values, undoing any exposure or color correction done on the picture.
If no input picture is given, the standard input is read.
AUTHOR
Greg Ward
BUGS
The luminance value is used for comparison of pixels, although in certain anomolous cases (ie. highly saturated colors) it is possible that
pextrem will not pick the absolute minimum or maximum luminance value. This is because a fast integer-space comparison is used. A more
reliable floating-point comparison would be slower by an order of magnitude.
