If it was easy, we wouldn't be having this discussion . There are motherboards that use the same SB820M and DO support 6Gbps SATA. I suspect their BIOS might have some good clues. It's not just the BIOS though, I am studying the datasheets of the SB820M, there could be a chance that pins are held high or low on the board which enables/disables certain functionality, or there are variations of that certain chipset that lacks features or has been disabled internally to fit a segment in the OEM market, intel do this with their chipsets, that's why PHY's are usually 3rd party though nearly every intel chipset has a built in PHY's, it's a way motherboard manufacturers can sell the higher end products.

I'm still hunting for the N54L Bios on the HP website, what version did your's ship with?. My last bios release will work fine on the N54L btw, the only difference between them all is the CPU. I was looking at the board on mine recently, I might be able to add audio, only a couple of components missing. Been looking in to this SATA III/6gbs and cannot get my head around how to enable it, the bios has no code whatsoever related to it. HP have probably crippled it on purpose to not compete with the main servers, though I will keep looking in to this. Overclocking/Underclocking may be an option in my next release.

Just put this page up. Will sort out a proper blog soon http://microserver.wikia.com/wiki/Main_Page

Nice to see someone else is using my BIOS, I am TheBay from AV Forums, there is a newer BIOS than what I posted on AVF, but doesn't really add much so haven't updated the upload yet. Now the N54L has been release I will work with this BIOS. I may start putting updates/uploads in here if it's of any interest?. I used to work for HP so no need to worry about my BIOS causing problems with your system as I use official tools. Dale
