This is a complex topic - and I was thinking you wanted to write your own extension, so I did not say anything yet.
However, where the information is stored for device driver loads at startup is in the odm class Config_Rules.
AIX starts in three phases:
phase 1: before rootvg is varyon
phase 2: varyon of rootvg
phase 3: rootvg is varyon (and top of /etc/inittab is now active; phase 1 and phase 2 is managed by the script /sbin/rc.boot)
To list the three phases of Config_Rules - coursely
Code:
for i in 1 2 3
do
opdget -q phase=$i Config_Rules
done
Also study the file /sbin/rc.boot.
Hope this helps - and if so - Enjoy!

Hi folks,
I tried to load a copy of redhat from CD to an HP6640C. The system reads the first disk and offers me a choice to use the graphic load or the text load. I selct either one and the system seems to start reading the disk then it reboots.

Hi,
I'm new here. Just started playing around with kernel compilation.

#include <mlib.h>
mlib_status mlib_SignalDownSample_S16_S16(mlib_s16 *dst,

const mlib_f32 *src, mlib_s32 factor, mlib_s32 phase,
mlib_s32 n);
DESCRIPTION
Each of these functions performs downsampling.
For monaural signals, the following equation is used:
dst[i] = src[i*factor + phase]
where i = 0, 1, ..., (n - 1 - phase)/factor.
For stereo signals, the following equation is used:
dst[2*i] = src[2*(i*factor + phase)]
dst[2*i + 1] = src[2*(i*factor + phase) + 1]
where i = 0, 1, ..., (n - 1 - phase)/factor.
PARAMETERS
Each of the functions takes the following arguments:
dst Output signal array.
src Input signal array.
factor Factor by which to downsample. factor >= 1.
phase Parameter that determines relative position of an output value, within the input signal. 0 <= phase < factor.
n Number of samples in the input signal array.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
