Apple Hardware Test for PowerMac G4 Mirror 1.42 Dual

hi, thanks for your help.
thirst, some answers to your questions :

1- Did it show up as AHT when Option booting?
no, it does show AHT when booting with option key... just the system on the local hard disk

2-When you're normally booted does only a Read me show up as the only file on it?
it is impossible to boot with the CD burned with "Disk Utility".
when i mounted the image disk on the desktop or the cd burned, i see the read me file.

3-Did you just use Disk Utility to Restore it to a CD?
yes, i use "Disk Utility" to burn the cd : a control-clic on the AHT image disk -> "graver" in french (burn). and the operation is ok. but not in restore mode.
So, I tryed to clic on "Restore": i can select the img source, but i can't select the good destination by drag and drop... i worked with a CD-RW or a CD-R, nothing... no possibility to restore the AHT on it.

For information, i do this on my principal computer (iMac 2,4 intel core duo). i need the AHT for my older powermac G4 1,42 Dual Mirror.
thanks.

First, sorry for my english level... that isn't easy for you to understand... but it's a good exercice for me 😉

On the Mounted CD, there is just the "read me" file...
when i want to see the hidden files (with "Transmit" by example), i can see some files et folders (like system folder...). But when i start the computer with option key, i don't have the choise for AHT... i don't understand...
Please, can you explain me how i can burn a image disque on a CD with the "Restore" step... because i think that when i burn normaly, i don't make a bootable disk.... What do you think about? Thanks

When the CD mounted and there is no hidden files, i don't see this :
Apps
Configs
of languagechooser.sc

The others are presents.

Yes, i tried a booting test with C key down. Same result.

please, can you test the AHT image disk that i downloaded ( http://download.info.apple.com/AppleHardwareTest/693-3994-A.dmg) ? and watch the content? just to be sure...

i have exactly the same content...

did you have try to make a bootable AHT disk with this image disk? did it be bootable?
