I am having the same problem, but am using the retail disk.
I've confirmed all the correct BIOS and tried buring a few different copies of iboot on different machines.
I have gotten this drive to read the retail disc with Empire EFI but hit a brick wall with that workflow so started again with iBoot.
System Specs:
Mobo: Gigabyte GA-X58A-UD3R
CPU: i7 930
RAM: 4GB G.Skill 10666 @ 1333MHz
Graphics Card: Sapphire Radeon HD 5770
Retail Snow Leopard disc
OWC 40GB SSD
Any thoughts? I was able to get an install through Empire EFI. Got the kext for my Graphics Card loaded, but never fully working (OSX did recognize it tho), but when I updated Snow Leopard i could not boot up again.
Thoughts? Thanks for the help everyone. I've been tearing my hair out here for days, just trying different tutorials I have found online.
