Dell Precision 6500 BIOS questions
I have a Precision 6500 I purchased in December of 2010. I have recently decided to replace the SSD in it with a larger SSD for the primary drive.
I have Windows 7 Ultimate 64 bit and I am doing fresh install from scratch. I have a secondary HD installed as well for mass storage.
While in the BIOS I noticed a few things that I thought were off.
First, it say the BIOS version is A04. On the driver download page it only recognizes the existence of A08 & A09. Am I safe going to A09?
Next, Under miscellaneous devices USB3.0 is unchecked. Does this mean my USB ports are actually capable of USB3.0 speeds if I check this? I have two external hard drives that could utilize USB3.0 speeds,
Next, the SATA settings indicate that it was set up for RAID. I have read that AHCI mode will allow TRIM and some SMART stuff to be available, but that in RAID I lose this. Can any damage occur from switching from RAID to AHCI right now?
Next, what is a "precision ON reader", and what are the ramifications of enabling that feature.

Well I have been able to narrow a couple things down. It does appear I have USB3.0 on the PC. Even though the specs for the machine did not mention them and the option was disabled in BIOS.
I have taken the SATA off of RAID and put it into AHCI instead. Nothing catostrophic happened.
Sounds like preicion ON is just junk I don't care about.
The new BIOS A09 installed OK. I don't see anything different (good or bad).
Tried installing the OS on the new drive and it won't boot. Going to attempt it again shortly.
