Hi all! Im a newbie so please give me a little time if i dont get my questions correct first time around. Thank you in advance!!

Firstly, im running SL 10.6.
I have tried several SL on my AMD system and only two were successful in booting. One being my current SL 10.6 and iatkos v7. Both required basic installations to work and a second install visit to add in any additional settings or the install failed? strange but hey-ho.

Anyway, my question is, i have searched high and low but cannot find anyone/any guides to get 10.6.4 working on an AMD?
I have tried a few "intel & AMD" discs but without success. They boot but fail install before i reach my custom settings for install stage.

As i have a working 10.6, is it possible to upgrade? i have tried without success from reading a few posts but nobody seems to confirm a working install barring vm type installs.

Please can anyone point me in the direction of a known working guide?
Also, im taking it that zephyroth is not supportive of SL as unmentioned?

Massive thanks in advance to all!! Sorry im new to forum and to SL on PC
