Upgrading Dell Precision M6300

I have a well cared for M6300 and rather than replacing it, I plan to upgrade it. I have purchased the following components:

T9300 processor to replace T7500

2x4GB DDR 2 PC2-6400 800MHz RAM

500GB Travelstar 7200rpm SATA 3 drive

Windows Ultimate operating system (not upgrade-from Yoda on eBay;  any relation??). Present system is Windows XP Professional

Questions, oh GURUS!

1.  Cannot upgrade Dell BIOS beyond A13- does not support hardware virtualization.  How to get around this??

2.  Will BIOS automatically recognize hard drive/RAM/new processor?

May have further questions as project evolves.  Computer software issues annoy me, but I am OK with hardware.  Have an Extra class ham license and I'm an orthopaedic surgeon so I'm pretty good with "tinkering", but please bear with my ignorance.  Thank you for your help in advance.

Is there any problem replacing a SATA 5400rpm hard drive with a SATA3 7200?

Thank you, qhn. Owe you some free bone or high power AM vacuum tube advice.

Thanks.

I have been throught the BIOS with a fine toothed comb and there is no place to enable hardware virtualization. Simply is not listed as an option. The original processor is an Intel T7500 Core2@ 800MHz. The processor could support it, but  I think that the problem is that the latest BIOS version supplied by Dell was released and abandoned before Windows 7 (A13).  Any way around that or is my reasoning flawed?

Thanks!
