If you are currently using the X8DA3 board with both the LSI Megaraid and either the Adaptec or Intel RAID working at the same time, would you please let me know what video card you are using? I've been trying to get this to work for over six months and cannot turn on the Adaptec or Intel RAID without turning off the LSI. I've installed every BIOS update I could find and have had a long, not-very-helpful correspondence with SuperMicro. I get a 'not enough space option rom' message at the end of the BIOS boot. I'm pretty sure the problem lies with the amount of option rom used by the video card as when I installed an old PCI Radeon card, I could turn on the Adaptec and have the LSI boot as well. Intel still did not let the LSI load, however. I'm currently using a Sapphire HD5750 card and while I'm not in the mood to buy a new one, I want very much to get this board up and running the correct way. Tell me what you got or did to get both RAIDs working. Thanks.
