It turns out that Dell did indeed turn of any RAID settings and hid it from the common user. Or rather didn't make it visible. What you have to do to enable RAID on the Dell Latitude E6440 is: - Download<wbr>file/bouk3i It's a flash toolkit by Intel with additional batch scripts mostly for Asus boards. You can use fptw to dump your current or flash a new BIOS. - Extract it to C:\. The new path should be "C:\FTK8_0.11\Windows" You can extract it, where you want. However, it will be easier to handle the next steps, if it is C:\. - Start > type "cmd" > right click > Open as Administrator. You need full rights to run fptw.exe - Type "cd C:\FTK8_0.11\Windows" to change your current directory to the toolkit folder - Type "fptw.exe -D backup.rom -BIOS" This command will create a dump (-D) of the BIOS section (-BIOS) to the file backup.rom. The Management Engine section for example is read/write protected, so it won't be possible to do a full dump. Then you can open the dump with "UEFITool" (just search for it on Google), then search for and extract the module SetupPrep, when you find it, run it trough the "Universal IFR extractor" which will generate a text document of the input. I attached my text document down below so that you can compare. SetupPrep IFR.txt The interesting part is in my case in line 2030. It tells us the name of the setting ("RAID0"), the hexadecimal address in the NVRAM (0x19D) and its possible values (0 - Disabled/ 1 - Enabled). In my 6440 the NVRAM 0x19D was 0, so disabled. To change the NVRAM download the following programm:<wbr>bootx64.7z An easy way to run the app, would be to place it on a FAT32 formatted thumb drive in a folder named EFI, so the path looks like this: "EFI\Boot\bootx64.efi". On each boot your notebook looks for this file and if it is found, it is started. If not, go to the boot menu (F12 if I remember correctly) and select your thumb drive at the UEFI boot section. You should then see a GRUB boot loader and possibly you will need to confirm that you want to continue. The command prompt, which you will reach, will be the place, where you can flip the RAID0 setting - amongst others. To make sure this tool finds the correct values, read out some settings first. To read out a value you need to write "setup_var <address>", to store values "setup_var <address><value>". - "setup_var 0x19D" should show you 0x0, which would mean the RAID0 option at address 0x19D is disabled. For most addresses you will see 0x0, so let's check for a more unique value .. - "setup_var 0x1AF" should display a value ranging from 0x69 to 0x7F, which is the value for the "Critical Trip Point" at line 1659 If not, you should abort and not use it. Otherwise you can enter "setup_var 0x19D 0x1" to store 0x1 at address 0x19D and activate RAID0. Then you can reboot and see what happens. If something went wrong, or you simple want to change the setting back to its default state, boot again from your thumb drive and enter: "setup_var 0x19D 0x0". I actually did this procedure on a A.07 BIOS by accident, however it turns out that I was able to downgrade to A.02 afterwards and my RAID config was still working. I don't know about any other BIOS versions though. Also, I want to remind you, that it was only for "Xsmile" over at the forum, that I was able to enable RAID, so the credit goes to him. We got most of the information from this website:<wbr>190354/ (Google translate works wonders on foreign languages) Lastly a more personal question. So I set up the Laptop, final specs: i-7 4810MQ 2,8 Ghz (no overcl), 16Gb 1866Mhz, AMD 8690M, 2x250Gb Samsung EVO RAID 0, Win 8.1 Pro 64bit, BIOS A.02 Mods: EC Retrofit, ODD SSD, eGPU: EVGA GTX770 SC, Corsair ATX, PE4L-EC060A, DIY BOX V1.1, dual monitor 1080p Nando, I read your eGPU post for the 6440 and you said its simply a matter of plug and boot in order for the TOLUD to lower, which I did. And the Laptop recognized the 770, but when I rebootet the laptop screen just went black (but still bg</value>-illuminated) I was able to see the mouse cursor, but nothing else. Even if I unplug the eGPU there's only a black screen. Please help me if you can. I'm not sure what I've done wrong.</address><address><value> Regards!</value></address></address>
