i dont know how to apply .kexct files to an installtion dvd, is there any how-to or tool that i can use for ?!
the file you mean could be usbiofamily.kext

If that is the one, copy that kext file into your desktop on Revision 2, and use Kext Helper to help patch that extension in. If all goes fine, the Utility will ask you to reboot your system and keep your fingers crossed. =) Most likely, in every scenario, installing kexts work for me.

the problem is, i can´t install rev2 neither rev1, cause i only have this USB Keyboard/Mouse combination, and with no keyboard i can´t install mac os ;( is there any possiblity to edit the iso file with the .kext ?

Yes, you should be able inject this kext before you get to the welcome screen. If not, try replacing the rev.2 usb package with the one included in rev.1 and repatch the DVD (since you said in your first post, that the USB Mouse and Keyboard combo worked with rev.1, right, "...i can´t use my USB-Mouse and USB-Keyboard (both Logitech) , so im not able to install this release. in 10.5.1. USB Support worked...")

that´s my idea, the only problem that i have is, where can i get a the bootsector
for the new "patched" dvd

or i will boot from the original release change the dvd and install from the patched one
if this works for me i will give you feedback

@standard, if your 10.5.1 works fine, then you only need the 10.5.2 update by eddie, you don´t need a clean install.

@WinLinMac01 , If some people want the support for Sata DVD, why are you saying they need a clean install? it´s not necessary , please think about the answers ok? they only need the new AppleNforceAta.kext not a clean install.

@roisoft where can i get this update (i hope its a PPF file for easy patching,
cause of missing VIA driver in 10.5.1, i am not able to install this release, cause my hdd´s
areßnt recognized ;(

I didn't realize about the support I gave for the SATA DVD (should have proofread). Yes, they only need the new AppleNforceATA, by Medevil.
How is going to do the 10.5.2 update when his combo does not work? If thats the case, he should rather stick with the 10.5.1 release, and then upload manually from there using eddie11c's update. =)

Not exactly, its not a PPF. Instead its a standard installer available at http://osx.kbot.de/comments.php?DiscussionID=300&page=1
for discussion purposes only. Unfortunately, at the time being, the link is broken, and should be repaired soon.

the update is a pkg and only works if you have a working 10.5.1, but if you want inject a kext into the ISO go (if you have a tiger or leo install) here if you are in windows, download transmac open the iso and inject your kext.

edit: you can try enable only USB 1.1 and disable 2.0 or plug your device after install dvd boot
