Well i got it to work!
ill post what i can
Esxi version: 4.1
Motherboard: Tyan S2865 Bios v3.02
Onboard NIC with 2 ports: Both work!!
Also i have a Intel PRO 1000 GT - works!
Chipset: Nvidia nForce 4
CPU Socket: 939
AMD Opteron 170 dual core
Storage: works fine, it picks up my 4 sata drives perfectly
Onboard raid: Does not work
other notes: i had a bit of trouble becuase i was a little lazy, just expected esxi to format the disks. i moved from a raid enviroment and i just ended up removing the partitions with gparted along with disabling the raid setup, then everything worked out fine.
i think that covers it, anything else?
