You can find Dell's diag/fixes for this BSOD here: Dell BSOD diag
Past experience tells me the 7B is a boot device failure and the second # is SATA RAID. When I've seen this in the past it's been because I changed the SATA RAID settings and confused Windows. This time I can't go back to the original MoBo and must use the new one which seems to have different settings or at least completely different SATA drivers. Neither Windows startup option will boot. Nor can I boot if I change the SATA to any of the four settings allowed. Nor will it boot if I completely disable SATA and try to boot from the PATA (Windows Vista) partition.
I've loaded Windows 7 RC1 on a different partition (and am currently using it), so I know the hardware is fine and functional. But I have dozens and dozens of applications on my older boots that I need to keep web development, graphics, and other business going. I groan at the daunting thought of reloading all the plugins and other settings for my graphic apps alone, much less setting back up all the sites and services for my web design.
I believe what I need is to somehow slip the correct drivers for the Dimension 9150 into the registry or at least get a repair to allow me to load/add drivers to a fix. But I haven't been able to find any way to do this. I don't really care about the old Windows 7 RC1 boot. It's the Vista one that has all my apps.
A perfectly acceptable alternative would be to upgrade the Vista to Windows 7 RC1, but when I boot from the DVD to do this, it tells me for an upgrade, I must boot 'normally' and then start the installation. Since I can't boot normally, that's out.
Any geniuses out there with a clever method of getting the right SATA drivers onto Windows Vista when it won't boot?
Thanks 1,000,000 to all who try to help!
