I have testing a sample motherboard on Q35 chipset with AMT 3.0 feature,SATA DVD-ROM and RAID1 on Intel Matrix.
I created bootable dvd-rom with Windwos 98 startup files(floppy simulation) and SATA driver for SATA DVD-ROM.
When i use IDE-Redirection to CD-ROM, redirection work properly, AMT machine booted properly from bootable dvd-rom that located on client computer.
If i tring to use IDE-Redirection to ISO file that created from this dvd-rom,AMT machine cannot boot.
Also if i removing the SATA driver from bootable dvd-rom it also connot boot.
Also if i unplug SATA DVD-ROM from AMT motherboard i cannot boot trough IDE-R.
The question is how the IDE-R working with cd-rom redirection,if i want to use cd-rom redirection i need to have physical cd-rom connected on AMT machine?
And why IDE-R not working properly with ISO file .. may be problem with the drive letter and windows 98 boot files?
This looks very similar to one of the forum questions posted before; please refer to http://software.intel.com/en-us/forums//topic/53581
Basically, you need tochange the BIOS settings when using the ISO image instead of the physical CD-ROM.
BTW, could you please give us details onthe OEM, BIOS and AMT firmware?
