Modified BIOS for Microserver N40L enables hidden features

Recommended Posts


I think one of the issues is that multi-port capability has to start with the eSATA chipset. If it doesn't have multi-port built in then it just can't happen, no matter what the BIOS. I would go with a SiL3132 card; mine has worked really well.

Help ! my friends ! the french newbie I am made a big mistake with this new bios, so that I cannot have any graphic card available (the onboard one neither the ATI 5450 i have been inserting in the pci slot).

The only option i can see to put everything back in place is to restore the bios default settings.

Can anyone help me to know what sequence i have to press so that i could restore the bios defaults ?? F10 for bios and then ?? f9 ??


Another question: i didn't succeed in putting the onboard 1GB NIC card available, i don't have any gigabit switch, can't i connect my french orange box (livebox 10/100 Mbit ports) directly on my onboard proliant's N40L gigabit card ???


you see, i am on a bad road to succeed withou you.

Thanks for all

Ok guys, after all this time, I have decided to flash the bios on my N40L. I'm having a major problem with creating a USB key. I've downloaded everything from links in this thread but when I use the HP tool to format the flash drive, when it completes there are several files on the flash drive that should not be there. Stuff like PDFs and other random things from my computer.


I've formatted the drive several times, tried different computers and different flash drives but the HP tool still places all these weird files once it completes.

I have found over the years that different makes/models of USB flash drives respond quite differently. For example, I've had some USB flash drives that work well with the MS Win7 DVD Download Tool and others that wouldn't at all. I would try some other flash drives.

Please check out the latest Step-By-Step Guide in HP ProLiant N40L MicroServer Build and BIOS Modification Revisited edited 2-3-2013



From my posting to MediaBiz at http://homeserversho...-options-setup/ -- part has been snipped out and copied below.............................


For instance, the 4th link on the “More Interesting MicroServer Links” page is titled ROM Firmware Upgrade from HP

At that page on HP’s website download the file SP54344.exe to your laptop or desktop and follow HP’s instructions to create a USB that can flash your BIOS.








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

1. Obtain a formatted USB Key media.

2. Download the SoftPaq to a directory on a system running Microsoft Windows 2000, Microsoft Windows XP, Microsoft Windows Vista, Microsoft Windows 7, Microsoft Windows Server 2003, Microsoft Windows Server 2008, or Microsoft Windows Server 2008 R2 and change to that directory.

3. From that drive and directory, execute the downloaded SoftPaq file: Simply double click on the SPxxxxx.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 the different methods for restoring and/or upgrading the firmware on the system.

4. After the USB Key is created, you may delete the downloaded file if you wish.

5. 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.


If you followed HP’s instructions (above) now you would be re-installing the factory BIOS currently on your N40L. This may be handy to have on a spare USB stick. Now create another USB stick with the Factory BIOS installed on it.


If you look at the USB stick you just created with Windows Explorer you’ll see (if you don't get these 11 files you may need to re-install the HP program):

















To flash the MOD BIOS you could use DieHard’s Link and in post #5 of that thread Camiloml has a 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 and replace the file O41072911.ROM on your USB stick created by HP with o41072911.rom – (IMPORTANT: the ROM file begins with the letter Oh NOT the number Zero – this is where many screw up and crash and burn)


Now, with your USB stick with the 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


When I did it I removed all hard drives from my MicroServer – inserted the USB stick and turned the MicroServer on.


The MicroServer does it’s thing and takes you to a C:\ prompt.


Reboot and hit F10 to get into your new BIOS and make the changes outlined elsewhere in the Forums to speed up all your ports.


I created the Flash drive on a Win 7 pro Machine --



Before Flashing your BIOS check these Documents:

Thanks for the help. I got it sorted out after I posted but there was definitely something strange with my flash drives that kept me from making it work initially.

Yep, they're definitely not all created equal, especially the U3 variety.

To complicate matters, all the flash drives I have are all the same type. I bought a Sandisk 4-pack sometime ago. I had to ask a neighbor to borrow one. :blink:

That's interesting. I have found Sandisk to be one of the better brands overall but, obviously, even they make some that don't work as bootables very well. FWIW, the Kingston 16GB DT101G2 seem to be good.

Yes, I've never had issues with Sandisk drives but I've ordered a Lexar and Kingston to have some variety. I actually have a Kingston plugged into my car radio that I forgot about. Its been there about two years playing back music without issue.

      I have a simple question about my BIOS from iLo4. Look at the picture and you will see a difference in the System ROM and Backup ROM dates.

      Hey guys,
      Not sure if this is the correct section to post this, but in a bit of a pickle after attempting to flash my HP Microserver N40L to the modified bios last night.
      The story goes - I've had myN40L microserver for the past few years running Windows 8.1 and acting as a media server for the house. I recently upgraded a laptop I have so had a spare Samsung 840 EVO 120gb SSD that I thought I'd throw in the microserver as the boot drive. 
      I ghosted the existing windows install (which was on a 250gb mechanical hard drive) over to the SSD, rebooted the computer and everything was working file. When I checked the performance of the SSD using the Samsung Magician software it indicated thatt the SSD wasn't running at full speed due to AHCI being disabled. I then did a bit of research and found that SATA port 5 (normally meant for an optical drive) that the SSD was connected to doesn't run at full speed and in IDE mode. I read that the modified bios that's floating around for Microserver's can fix this.
      So I flashed the bios to my machine however now when I boot up it gets to the loading screen for windows and then errors and reboots. This boot loop just continues constantly with no way to get into windows.
      I've tried setting the hard drive mode to both IDE and AHCI in BIOS with no success, I've reverted the BIOS back to default settings, took out the CMOS battery overnight, tried to re-flash back to default HP firmware, re-flashed the modded BIOS with no drives in the server and even run the windows 8 startup repair with no success whatsoever, it just continues to error and boot loop.
      I did leave all 4 of my other SATA hard drives in the machine when flashing the modded bios originally so don't know if this affected it. I wish I'd just left the original BIOS on there now.
      Is there anything I can try to fix this? I'd really prefer not to have to reinstall windows 8 as it took me awhile to set everything up for media (Sonarr, CouchPotato, iTunes, Serviio etc).
      Any help is greatly appreciated.
      Cheers Benny

      Bought this ML10v2 a few months ago and have been hitting wall after wall, frustrated- putting it away for a few weeks, and then trying again. I can not get it to boot from a USB and have not figured out how to recognize and identify drives!
      I have gotten iLO4 working with a valid key, I have updated the SPP, registered on who knows how many HP/HPE pages, looked through the documentation- but still can't get the machine to boot to my Linux USB for installation.
      This seems like a basic step, but I've kind of lost my objectivity at this point and wanted to ask for help. Is there something I need to do in iLO4 to have it recognize the install media or my drives? I can't seem to make sense of the Virtual Media field.
      I want to install Ubuntu 16.04 Server- HP/SPP says it supports Canonical. How do I get the machine to 1) open into BIOS? is it F2/F9/F10/F11 during boot? My POST sequence never seems to get past 10%, and then 2) recognize my hard drives, no matter what number SATA cable, it doesn't see them. I can only open the iLO4 manager from another computer on my network, so I can't open it on local host like the (very helpful) Joe Stutsman videos and instruction guides suggest.
      Anyhow, any input on this configuration would be appreciated. I know I'm missing something, but want to exhaust all options before I return this.

      I upgraded 2 identical systems (both running windows 7) to SSDs and restored images via WHS 2011 and noticed that one of the systems is not running AHCI mode (according to AS SSD benchmark and device manager). I made the 2 registry changes already in windows according to this guide....
      http://www.sevenforums.com/tutorials/61869-ahci-enable-windows-7-vista.html   I then made sure that the BIOS had SATA configured as AHCI (and not IDE). After reboot, I did not get prompted to install the AHCI drivers and the performance is significantly less with the system that appears to be running in IDE mode.   The following are two strange things:  1. Changing the BIOS setting to AHCI or IDE never gives me a BSOD. 2. Stablebit scanner states that both TRIM and NCQ are both working on the SSD and from what I can tell NCQ cannot run without AHCI mode.   This system apparently appears to be "stuck"... in what appears to be IDE mode...Any ideas on what to try at this point? Am i looking at a clean install or even worse... corrupted BIOS?    Thanks!   nlitend1
