Im looking at picking up an old alienware with this mainboard in it. I have read that the mainboard actually supports up to 8gb ram and that it can handle a 512mg video card. It looks like you may have done some bios tweaking and such to allow for significant upgrading beyond original bios limits.  If this is the case wondering if you would share the program. I've read that this mainboard seems to have issues with seeing new hdds larger than 120gb(at least in the alienware model I'm looking at) and I'm hoping that among other improvements if you have made a bios upgrade that it might also address this issue. 
Thank you in advance,
