Okay, well I was able to get the BIOS to accept AHCI without a blue screen.
Unfortunately the boot time from BIOS screen to loaded desktop is 2.5 minutes. This is still a good 45 seconds slower than my HDD.
The ports are Intel controlled SATA lll 6.0 slots.
I did not run any additional r/w tests as you suggested and I am mostly working on the boot time now.
If I could get the boot time to be anything quicker than my HDD I would accept that, and then we can try to find out why the speeds posted earlier are still not where they need to be.
I am not sure if this means anything to you, but I noticed after changing the registry value and then restarting the pc in AHCI, there were two driver
searches that just kept searching and never loaded. they were ata 1 and ata 2. I did receive the message to restart to complete the process, but I gave it about 5 minutes to see if it found those 2 drivers
. I went to those two drivers in my device manager and asked it to search for the best driver (internet) and I was told that I had the best driver and the devices were working properly.
When I restarted the pc, I didn't get any errors or blue screens, or even another driver search....just two and a half minutes of waiting.
Any other thoughts would be great,
