it was realy easy

How about the hard drive? How did you hook up? Using the on board SATA port?

I use a SATA Drive with 1TB at the internal controller.

I got a similar bord, got ESX 4.1 installed on the IDE but what drivers did you use for the SATA interface to use as DataStores?

Turns out the community Community Unified oem.tgz v1.1.0 did the trick: http://www.vm-help.com/esx/esx3i/customize_oem_tgz.php

How did you did it?

I have a P5G41-M LE, and I just can't boot ESXi 4.1 Update CD. It stops with this error:

Booting: MBI=0x00010108 entry=0x00400256

Any idea?

Finally got it to work.... and completely! I was having two problems: memory recognized at 800MHz, but only working correctly at 667MHz, and ethernet built-in not supported directly. Got the driver from viewtopic.php?f=12&t=1876&p=5389#p5389, and followed instructions from http://engwar.com/post/392 to add the support to my installation CD.

So here's the description that can be added to supported hardware list:

MotherBoard: P5G41-M LE
CPU: Intel Core2Quad Q8400 @ 2.66GHz
RAM: 2*4GB DDR2-667
DVD-RW: LG PATA
NIC1: Atheros / Attansic atl1e Ethernet Adapter [1969:1026] (built-in)
NIC2: Intel Pro 1000/GT
BIOS: default values
