LohnenNicht, to solve this problems, unplug the network cable or disable all the ethernet adapters in bios, you can enabled after the install , the same for firewire

there are 3/4 options behind the dvd, left-to-right order

1. Master
2. Slave (use this one for Slave)
3. Cable select (this works in windows but it cause problems in mac)

No it isn't the problem, the jumper is set to second choice "SLAVE" one.

no. It doesn't work. Login still crashes.

Plz, the community..
Anyone has the same branch of CPU (one core) and the same motherboard and as well got LEO installed
successfully. Plz tell me where did you start to have problems, which steps did you follow to solve them?
This guide will not only help me but as well other many people. As "LohnenNicht" said this mobo is very populer.

At least anyone knows "Zepyroth" will let us install the most perfect OS LEO on our mobo with rev2?

It´s a strange thing, because i don´t have this kind of problems with this motherboard.

roisoft, maybe you can help us all out and give us your system specs, including your BIOS options and bootflag options.

Yes plz, raisoft can you do that?

LohnenNicht, did you check your md5 hash of your iso?
Did you download it from Pirate as Mac OS X Leopard 10.5.1 for AMD SSE2/SSE3 (32bits)?
