a15457 1 Posted December 4, 2012 Share Posted December 4, 2012 I've been planning on getting a Hotway H82-SU3S2 http://www.hotway.com.tw/products/h82-su3s2.htm later when I need some more disk space. (yes I know that this enclosure costs more than the server ) I was originally going to get a USB 3.0 card for my N40L as I'd read that the eSATA port is only at half speed without modding the BIOS. Now though with this little thread I'm thinking I might just get me one of these enclosures and re-install windoze after modding the BIOS. Here's a question for those with a little more experience than I, would I get more throughput through USB3.0 than eSATA? given that I already have a RAID card using the PCI-Express Gen 2 x16 slot leaving the x1 slot for the USB card. Thoughts anyone? PS. Massive thanks to Alex for the info! Nice work dude! Link to post Share on other sites

cskenney 155 Posted December 4, 2012 Share Posted December 4, 2012 Joe_Miner is now going to need to re-route that eSATA cable back out of his box so he can give this a try. Link to post Share on other sites
Alex.Covecube 5 Posted December 4, 2012 Author Share Posted December 4, 2012 I'm glad that you guys found this useful. It took almost the entire day to figure out I forgot to mention one other important thing that I found: The unlocked BIOS cannot boot if your SATA controller is in RAID mode. This is not an issue if you're running in AHCI mode, and it's not an issue with the official BIOS. I've noticed that the RAID BIOS drive enumeration process never shows up during the boot cycle. This is something to be aware of. I believe this means that if your server is set to RAID mode, you will not be able to boot your system if you flash the unlocked BIOS. I didn't spend any time diagnosing this problem because my goal was to get port multiplication working. This is not destructive, because you can simply just flash the official BIOS back. 1 Link to post Share on other sites

I've owned 3 different USB-3 PCIe cards; 2 of them did not work well; 1 of them didn't even perform as well as USB-2. I finally got a StarTech card that performs pretty well: http://ca.startech.com/Cards-Adapters/HDD-Controllers/SATA-Cards/2-Port-PCI-Express-eSATA-Controller-Card~PEXESATA2 Link to post Share on other sites
TheBeagle 0 Posted December 5, 2012 Share Posted December 5, 2012 Can someone please provide a link to a BIOS update for the N40L (with some basic instructions) to unlock the features that are being discussed on this thread? Thanks in advance for any assistance that can be offered. Best regards to all. TheBeagle Link to post Share on other sites

TheBeagle 0 Posted December 5, 2012 Share Posted December 5, 2012 Thanks very much Joe. It looks like I'll need to do some reading before attempting a BIOS upgrade. I already have WSSE 2008 R2 installed on the SSD that I mounted in the N40L, so I hope the upgrade doesn't mess up the boot on that install. Thanks again for the response. Best regards to all.

a15457 1 Posted December 5, 2012 Share Posted December 5, 2012 (edited) Hey Beagley beagley ... I'd re-read the beginning of this thread. Just to be super sure ... before changing anything ... Switching between AHCI / RAID changes the hardware ID of the SATA controller. This is akin to swapping in a brand new controller. Because of this, the old controller driver in Windows will not recognize the new mode and Windows will refuse to boot. The easiest way to switch this mode if you really need to is to re-install Windows. Edited December 5, 2012 by a15457 Link to post Share on other sites
ikon 439 Posted December 5, 2012 Share Posted December 5, 2012 There is a way to switch from AHCI to RAID, and back, without having to reinstall. It involves a few steps, but I have done it myself and it worked. Here's a URL to get you started; there are lots of others: http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/changing-from-raid-to-ahci/4c94f678-6bd1-48a6-b871-8872c841023a Link to post Share on other sites
