Pardon if it's the wrong category to post...need urgent assistance - HP pavilion DV5

[Da Vinci Code]

Hi, BDMaster!
DV5 and HP DV6 models until middle of 2009 are very good laptops for getting an experience of BIOS modding.
That bioses are not RSA signed and can be restored easily if Boot Block not damaged.
I made many manipulations with Bios menu, deep modding (for ex. unhide Fan and chipset control for AMD platforms).
I found good option in IDE configuration named SATAHotPlug. It is actual for 4 devices (first hdd, second hdd-if 17 inch laptop, odd and removable hdd to e-sata port).As default, only 4 device have SataHotPlug enabled. I removed ODD and plug second hdd caddy then switch ENABLED for 2 hdd. I can change HDD without restarting OS and hdd volumes can be initialized online-good opton.
But this working at Intel platforms only. I don't like AMD platforms because it haven't useful options, more loudness and not so power saving as Intel.
At reading mode Intel working for 4 hours from battery, AMD for 2,5 hours.
Also North Bridge malfuntion is famous reason if laptop not start at once
