@kael, I make a successful install of iATKOS patched for AMD, everything works fine with the kexts from 1-st release of Zephyroth.
Update with no problem to 10.5.2 with eddie11's pkg , but GraphicUpdate doesn't work. Pc_efi on iATKOS not work for me.

Do you have about 2-3 minutes delay with black screen after update to 10.5.2 when booting?Do you use the 9.20 kernel if w/o PC_EFI?What is the overall performance?

Regards!

I'm having the same problem with the dvd rebooting soon as it begins to load. but Zephyroth's 10.5.1 amd, did work for me just couldn't get the diskutil to partition my SATA HD. it could see it and display info about it, but couldnt modify it. any help would be great.

what is EFI, i know it has something to do with BIOS and booting. is it something i have to install or change my partition to BEFORE trying to boot this DVD?

Please tell us your spec first.For the disk utility formating, maybe you can try IDE HDD,I once solve the same problem by changing the SATA HDD.Can you re-partition your whole HDD?

EFI:http://en.wikipedia.org/wiki/OSx86

@kael, Yes I had black screen each time I start the Leo. No new kernel, couse it want pc_efi, witch not work for me.
Performance was the same, I think couse of using the old kernel.

@althon,
If so,there is no need to upgrade to 10.5.2?--Zephyroth's v1 works perfectly with my machine.

I've tried repartitioning the whole drive and it wont, it just keeps giving me an "input/output error" message. i've tried erasing also. i've tried using terminal to do it by hand also. no luck. i do have some spare IDE's around but this box dont have IDE ports only SATA.

I read somewhere that there was an issue within diskutil that was not working properly. but i dont have any other OS X disc to try with. thats the main reason i downloaded this new 10.5.2. EFI. hoping if this one didnt intall completely then i would just use it to partition the drive then simply use the first disc to do the intall on the newly/correctly formated drive.

btw. im not trying to dual boot at this point just want to try out Leopard. seeing as how i've always only used Windows.

If you can not use IDE,you can try to download Tiger 10.4.9 v3 by uphuck team,it is universal one fit AMD and Intel and the disk utility of it may solve your problem.

cool, im going to try that thanks.
