    HP ProLiant N40L MicroServer Build and BIOS Modification Revisited

    clip_image001

     

    Early last year I purchased my first HP ProLiant N40L MicroServer (“MicroServer”) and wrote about some of the things I did to build-out my MicroServer after flashing the modified BIOS from BIOS-MODS. After building-out my second MicroServer that summer and the many things I’ve learned over the last year I felt it was time to re-visit and re-fresh my first Blog.

    HP N40L ProLiant MicroServer

     

    The HP N40L ProLiant MicroServer’s I purchased came with 2GB of RAM, a 250GB Seagate HDD, and a 150W power supply. One was part of a combo package that included Windows Home Server 2011.

     

     

     

    Check the Stock BIOS

     

    One thing I found useful: With my first MicroServer I didn’t check out the Stock BIOS in the MicroServer before flashing it and afterwards I wished I had -- before flashing the BIOS of my second MicroServer I pulled the HDD that came with the MicroServer and the first time I powered-up the MicroServer I hit F10 and checked out what was in the Stock BIOS.

     

     

     

    In summary, when I first powered-up and hit F10 the MicroServer was configured with:

    · The stock HDD was removed (no HDD’s were in the MicroServer)

    · The Stock 2GB RAM was in the MicroServer

    · No PCIe cards were installed

    · A monitor, USB keyboard & mouse was attached to the MicroServer

    · Nothing else was attached to the USB ports

    · The NIC was not plugged into the network

     

     

    Figure 1 shows the MAIN screen of the Stock BIOS.

    Flashing the BIOS

    Caution: This isn’t a project for the inexperienced or faint of heart because you may be voiding any warranty you have as well as easily destroying or bricking your entire system. Proceed with the steps in the following reference links and Figures at your own risk.

     

     

    In the original HP MicroServer N40L Build and BIOS Modification I wrote how I flashed the modified BIOS from BIOS-MODS to my first MicroServer using John Zajdler’s, @DieHarder on twitter, Diehard in the HomeServershow.com forums, guide and suggestions. DieHard is a rock star! I followed his notes and suggestions and had no problem flashing BIOS-MODS modified BIOS that would unlock many of the hidden features on the MicroServer – especially enabling me to set SATA port 5 (the mother board port for the ODD (“Optical Disk Drive”) if installed) and port 4 (the eSATA port on the back of the case) to AHCI and at a higher port speed than it’s default. At that time I downloaded HP’s SoftPaq from cvscorp, prepared a bootable flash drive and copied the file over from BIOS-MODS. Since that time the Forum thread started by DieHard has grown, as of this writing, to over 15 pages and 290 messages and continues to grow.

     

    When issues surfaced on cvscorp’s availability last year DieHard made copies of the necessary files available from his SkyDrive account (Get Flash.Zip & SP54344.exe).

     

    With the Flashing of the BIOS for my second MicroServer I wanted to document my experience and put together a step-by-step guide that was all in one place, starting with the original HP BIOS.

     

     

     

    Step-By-Step Guide

     

    At HP’s webpage, Systems ROMPaq Firmware Upgrade for HP ProLiant MicroServer (For USB Key-Media), download the file SP54344.exe to your laptop or desktop (I used my Windows 7 Professional Desktop Machine) and follow HP’s instructions to create a USB that can flash your BIOS.

     

    HP Installation Instructions (changes made to improve clarity, check the WEB Page above for the original full text):

    USB Key - HPQUSB.exe is a Windows-based utility to locally partition, format and copy necessary files to a USB flash media device (“USB Key”) through the Windows environment. The created USB Key is made bootable and ready to locally restore and/or update the firmware (“BIOS”) on the system.

    1. Obtain a formatted USB Key.

    2. Download the SoftPaq to a directory on a Microsoft Windows system and change to that directory.

    3. From that drive and directory, execute (Figure 2) the downloaded SoftPaq file: Simply double click on the SP54344.exe file and follow the installation wizard to complete the SoftPaq installation process. At the end of a successful installation of the SoftPaq a web page will automatically appear to provide you with a link (Figure 3) to create a USB Key – alternatively, after the successful installation of the SoftPaq you could change to the directory the SoftPaq was installed to (default is C:\SWSetup\SP54344) and either execute start.htm in that directory or HPQUSB.exe in either C:\SWSetup\SP54344\Flat Files or C:\SWSetup\SP54344\USB Key directories.

    If you followed HP’s instructions (above) you would have created a USB Key for re-installing the factory BIOS currently on your N40L. This may be handy to have on a spare USB key, so set it aside and create a second USB Key with the Factory BIOS installed on it.

     

    That first USB Stick that you created and set aside can be used as your System Recovery Key if you’re system should fail to Boot after attempting to Flash the BIOS.

    Note: I don’t know why the USB Drive and the Flash Disk file counts are different but they both worked.

     

     

    To flash the Modified BIOS ("BIOS-MOD") you need to first get the BIOS-MOD -- you can follow DieHard’s link to BIOS-MODS thread for the HP Proliant Microserver AMI BIOS-MOD and in Post: #5 of that thread Camiloml attached the file that you can download, o41072911mod.rar, or just click on this direct link to the zipped file o41072911mod.rar -- o41072911mod.rar is what you want. Un-zip it with Winzip or some other SW package and you’ll have the file o41072911mod.rom, thanks to the hard work of the people at BIOS-MODS!

     

     

     

    Rename o41072911mod.rom to o41072911.rom. Replace the file O41072911.ROM on your second USB Key created by HP with o41072911.rom – (IMPORTANT: the ROM file begins with the letter Oh, NOT the number Zero – this simple error has been the genesis of many crash and burns during attempted Flashs. Another big danger is a power interruption to the MicroServer during the Flash – attach your MicroServer it to a Uninterruptible Power Supply (“UPS”) if one is available during the Flash. Another common problem has been an incompatible or just plain bad USB Key. For other failures or issues check HP’s Troubleshooting guides.) The uncompressed o41072911.rom is also in Diehard’s SkyDrive folder Flash.

     

    Now, with your USB Key with the BIOS-MOD ROM file replacing the Stock/factory BIOS ROM (notice the file names were the same and they are the same size) you can flash your BIOS per HP’s instructions: “Insert this USB Key into the USB Key port of the system to be updated and power the system on to boot to the USB Key”. I created my USB Key with the BIOS-MOD on my Windows 7 Pro Desktop Machine. I’ve used 2 different Lexar 8GB sticks, a Team Fusion Plus 8GB stick, 2 no-name complementary 0.5GB sticks from an Alumni group, and 1 no-name 1GB stick I got at a trade show – all worked for me.

     

     

     

    In preparation to Flash with the BIOS-MOD I had the MicroServer in the following configuration:

    · The stock HDD was removed (no HDD’s were in the MicroServer)

    · The Stock 2GB RAM was in the MicroServer

    · No PCIe cards were installed

    · A monitor, USB keyboard & mouse was attached to the MicroServer

    · Nothing else was attached to the USB ports

    · The NIC was not plugged into the network

     

     

    With the MicroServer turned off I inserted the USB Key, the one I had created with the BIOS-MOD added, into the top USB Port on the front of the MicroServer and, after plugging in the power cord, I turned on the MicroServer.

    NOTE: The process will begin instantly: If the USB Key is in a USB port on the MicroServer when you power it on – the whole process is automatic – as soon as the USB Key is seen during POST the MicroServer will begin to flash your BIOS – and will need roughly a minute or more to complete the process and finish to the C:\> prompt.

     

     

    This is how the process went for me (times in seconds) after first checking that all plugs and cables were connected:

     

    _0sec   Press power button to energize the MicroServer

    10         HP ProLiant MicroServer Splash Screen

    13         Splash Screen Blanks out

    15         BIOS Starts initializing Processor, USB Controllers

    20         2GB Memory detected

    25         Auto-detecting USB Mass Storage Devices

    28         Screen Blanks out

    30         Screen Flash then blanks out

    32         Post Prompts displays – dots count across screen to 35 Sec Mark

    37         Copyright Screen displays and indicates config.sys/autoexec.bat are about to execute

    39         DOS Command Shell copyright displays and loading ROM Image notice displays

    42         Screen fills with characters

    46         C:\> is displayed at bottom of screen

     

    (See the Video I recorded of the BIOS-MOD Flash)

     

     

     

    The Flash of my second HP MicroServer with BIOS-MOD was complete at the 46 second mark.

     

    Caution: DO NOT power down the MicroServer before you see the prompt.

     

    After you’ve powered down the MicroServer then power it back up (or simply hit Cntl-Alt-Del to restart the MicroServer) and hit the F10 Key to get into the BIOS and check out the new things that are visible.

     

    The MAIN screen of the Modified BIOS from BIOS-MOD will appear as shown in Figure 8.

     

     

     

    clip_image020

     

    Figure 8: MicroServer "ROM-BASED SETUP UTILITY" MAIN Screen -- Modified BIOS

     

     

     

    Notice the difference between Figure 8 and the Stock BIOS shown in Figure 1 with the additional BIOS Tabs of PCIPnP and Chipset. BIOS-MOD doesn’t modify the Stock BIOS except to make visible code that was already in the Stock BIOS but had been hidden.

     

     

     

     

     

    Step-By-Step Guide – Critical Path Check List

    Caution: This isn’t a project for the inexperienced or faint of heart because you may be voiding any warranty you have as well as easily destroying or bricking your entire system. Proceed with the steps in the following reference links and Figures at your own risk.

     

     

    ______ 1. Get Systems ROMPaq Firmware file SP54344.exe from HP HERE

     

    ______ 2. Get BIOS-MOD o41072911.rom from BIOS-MOD HERE or BIOS-MOD HERE or BIOS-MOD HERE or Diehard’s SkyDrive folder HERE

     

    ______ 3. Change to directory where you downloaded or copied SP54344.exe in step #1.

     

    ______ 4. Double-Click to Execute SP54344.exe – follow installation wizard to create a bootable USB Key (for best practice for disaster recovery create an extra).

     

    ______ 5. Copy o41072911.rom (that you got in #2) to USB Key (from #4) – you will want to replace the original O41072911.rom from HP

     

    ______ 6. Move the USB Key (from #5) to any available USB port on the MicroServer.

     

    ______ 7. Turn on the MicroServer and wait for the C:\> prompt.

     

    ______ 8. Remove the USB key -- Reboot or power cycle the MicroServer and hit F10 to enter the ROM-BASED SETUP UTILITY – success will look like Figure 8.

     

     

     

     

     

    Modifying the BIOS

     

    Starting from the MAIN screen shown in Figure 8 above and using information I had found at Message #1217 and NAS Build Guide I moved through a number of screens to set Ports 4 & 5 to use AHCI and set all Ports to be external SATA Ports (basically enable hot swap).

     

    From the MAIN Screen I went to => Chipset Menu => Southbridge Configuration => SB SATA Configuration => and set the following:

     

    OnChip SATA Channel [Enabled]

     

    OnChip IDE Type [IDE or Legacy IDE](1)

     

    SATA IDE Combined Mode [Disabled] -- sets Ports 4 & 5 to use AHCI

     

    SATA EPS on all PORT [Enabled](2) -- sets all Ports to be external SATA Ports

     

    SATA Power on all PORT [Enabled]

     

    Notes: (1) OnChip IDE Type can be set to IDE or Legacy IDE – I have one MicroServer (WHS-2011) set to IDE (see Figure 9) and the other (S2012E) set to Legacy IDE (see Figure 10) and haven’t noticed a performance difference between the two, YMMV; (2) setting all Ports to be external SATA Ports will make all of your Ports to be Hot Swappable – this is something you would need later if you want to use the Port Multiplier functionality of the eSATA Port (Port #4) – there are registry hacks that will remove the hot swap functionality from specific Ports but I didn’t bother, again YMMV. A link to the steps outlined by Alex to enable the Port Multiplier on the eSATA port can be found in Useful MicroServer links and References that highlights the necessary posts to read in the thread Successfully enabled Port Multiplier on eSATA. Depending on your planned setup you may not want to Disable SATA IDE Combined ModeLoneWolf found that disabling SATA IDE Combined Mode also disable the ability for the MicroServer to see his HP Smart Array P410 Hardware RAID controller. YMMV.

    clip_image024

     

    Figure 10: "OnChip SATA Configuration" Configuration OnChip IDE Type [Legacy IDE]

     

     

     

    Finishing up my modifications in the OnChip SATA Configuration screen I returned to the MAIN screen. From the MAIN Screen I next went to => Advanced => IDE Configuration => and set the following:

     

    Embedded SATA Link Rate [3.0Gbps Max] -- forces the SATA Ports to run at 3.0Gbps Max mode

    Be sure to SAVE your changes when you EXIT the ROM-BASED SETUP UTILITY!

     

     

     

    Conclusion

     

    After flashing the BIOS-MOD and making a few minor changes in the BIOS I was ready to add additional RAM, OS drive and OS, internet cable connection to the onboard NIC, data drives, PCIe cards and many more things to this great little box. Currently, I have one MicroServer in production with WHS-2011 (Figure 12) for my home files management and providing a bare metal backup of my client computers.

    Hello Joe, Marvelous documentation and discussion! I just got my N54L. My planned configuration is a RAID array on a P420 RAID card and 16GB of memory. If I use the modified BIOS, what settings should I leave/change? Or do I need to use the stock BIOS and only 8GB? Many thanks, Alan

    Hi AGS: I don't have any experience with the P420 but some have found issues with the P410 and some of the changes after BIOS-MOD http://homeservershow.com/forums/index.php?/topic... -- for a production system I wouldn't go with anything over 8GB ECC -- 16GB is OK for a home lab with non-critical data. Be sure to post more questions in the Forums and tell us about your build.

    Thank you for your prompt response, and your guidance. Would you please flesh out your implicit concern about operating a "production" system with 16GB of RAM. This will be used at home, but it will be a "mission critical" part of the infrastructure. I don't mind the work to get it working, but I do need to be sure that it's solid when I'm done building it. My plan was to run a few VMs as well as serving up data, so 16GB rather than 8GB would be much preferred. If I mod the BIOS, but leave all the settings as is, might I be able to see 16GB and the Smart Array card?

    In the Forums check the threads "Useful MicroServer Links" and listen to HSS 212 and in "MicroServer Hardware Links" read thru some of the threads on RAM. You don't need the BIOS-MOD to see 16GB RAM -- assuming your machine will see 16GB.

    I have now successfully modified BIOS on HP ProLiant N40L MicroServer. I can now see the PCIPnP and Chipset options in the BIOS menu. Does anyone know if I can use a DVD/CD (ODD) as a boot device?

    Joe Miner, thanks a lot for such a valuable thread. Thanks to all of you I have just purchased and flashed a N54L Proliant. Browsing the BIOS-MOD options I came to two options that I don't know if I have to touch: PCIPnP -> Plug & Play O/S. It came set to "NO". Do I have to set it to "Yes"? Chipset -> NorthBridge2 Configuration -> Internal Graphics Configuration -> AMD 880 HD Audio. It came set to "Disbled". Do I have to set it to "Enable"? I'm going to install Ubuntu 12.04... Thank you very much again.

    Hi Joe, I have followed your instruction but it seems to get stuck because it cannot find the 041072911.rom. as advised I did not change the letter 'oh' to 'zero', but this shows that it is still looking for the 'zero'. Can you please help? Rjo

    Hi RJO! Sorry to hear you are having problems. Check Messages 408 & 413 in this thread http://homeservershow.com/forums/index.php?/topic... Let is know if that works. If not give us more detail in the forums on how you did the prep for the Flash. How is your MicroServer configured? RAM? HDD(s)?, USB Ports?, PCIe Cards? brand/type of Flash drives (1 with the stock BIOS and 1 With the BIOS-MOD)? Network connection? Where did you download the BIOS-MOD file? What files are on each of your flash drives? The stock BIOS has an "oh" for the first character of the BIOS name so it is looking for and will only load o41072911.rom or O41072911.rom and will fail if it sees a 041072911.rom. did you unpack it from the RAR file that was on the BIOS-MODS site? Have you tried a different USB stick? Please post in the Forums at http://homeservershow.com/forums/index.php?/forum...

    I prep the flash using a win2011 sbs server. Microserver is an HP Proliant NL 40, 4GB Ram, no HDD plugged. I am using the onboard USB port(tried other ports as well). Brand of flash drive is imation 8GB and SanCruizer 8GB. Network cable unplugged.I unpack the RAR file from the direct link you provided above. I have tried different USB stick. Also changed the letter oh from lowercase to capital. The error has now changed to "ROM File 041040~1.rom does not exist", " Line 274, Error 0x3".

      It's a good looking box that I hope will perform well and have plenty of features.  I've read good things about the Deco series and there were a few good sales last year on the M5.  I really should test the M5!
