    1. Then we wouldn’t have Colorado, Chicago or other chaos.Black men make them without marriage. White men are starting to do that as well. But white men also make them IN marriage and then leave the family and make a new family and forget about the other children from the previous marriage, two, three and four times. Yes, I am saying it. Women can’t raise boys to be men. WIthout men raising men, the next generation will have none.What is happening in the USA? Waiting for the irresponsible men to start making excuses.

    2. Your path to Halfhil is suboptimal for Alliance: Just jump of the ship and swim west (if you can waterwalk even better, Waterstriders are my favorite pet now), there you can find a path up the mountain to the Karasang Wastes bordering the Valley of the 4 Winds,from there just go north and then west to halfhill.

    3. Tack Malin! Ja visst låter det läskigt att sånt man använder till golv inomhus kan självantända! Som tur är slipper jag ängslas för just det eftersom vi använder såpa istället för vax:):)Anna


  1. Impossible to take firmware to HP site, the server must have always a active guaranty. Thanks for availability this file.

  2. I have a Proliant N54L with 041 bios installed. After updating to Windows 10 my ethernet no longer works. I tried to follow you upgrade procedure but I believe it is the same as I have installed. Any suggestions to get this to work.


  3. warning.

    I had the same problem, a dead LAN connection after win10 upgrade.

    ran this update, and it has bricked my Microserver.

    it powers on, but no display, no post beeps etc. tried a bios reset, external display card etc, but no good.

    if anyone has had something similar & able to restore it, then let me know.


  4. Fixes ACPI incompatibility in proliant N54L G7 microserver bios.
    ACPI error is root cause of hanging installation of windows server 2008R2+ on this hardware.

    Thanks so much for making this available, taken me days to get here and I’m very grateful to have my server up again. Can’t believe HP think its OK to keep this update locked away, the server is almost useless to windows folk without it

  5. Had to load optimal settings in bios after doing the update

    then my network cable worked

    stopped working because i upgraded to windows 10
    might just needed to restart it a few times

  6. When I first tried to create the USB key on Windows 10 in another machine, it did not work (“could not format the USB Drive” error, which rendered the USB Drive corrupt), this was solved by trying the procedure on Windows 7 instead. However, another error came up (Write-Protected), which was then solved by formatting the USB Drive (8GB capacity) via command line (diskpart -> list disk -> select disk -> clean all -> create partition primary -> format fs=fat32 -> assign -> exit. Note: be very careful when following this procedure, so that you won’t delete other drives).

    With this, I proceeded to use the HP USB Key Tool on the formatted USB Drive (on Win7 still). Finally, the tool worked, and all that was left was to reboot the N36L machine with the USB Drive connected. It all worked pretty fast, and when you see the prompt “C:>” then you are done, and can restart the machine without the USB Drive on.

    Note that on my case it was not necessary to reload the optimal settings on the BIOS for the NIC to work again.

    Thanks for the guidance! And good luck to everyone that is still on this problem (by the way, HP has let me down with their maintenance policy).

    1. I had this issue too so I used Rufus to create a bootable USB flash drive (FreeDos). Then copied the files across to the drive.
      Booted to the Rufus based DOS, then just ran the flash.bat and all went well.

      p.s. you can repair any USB drives damaged via diskpart, need to clean and create partition again, format.

      1. An amazing post which includes true value based inafimotron in the concise manner. However, I expect if you could have written more about it. Overall its a nice post and please keep sharing more on the same topic.

      2. December 7, 2012 – 7:17 pm Great articleFacebook and Twitter are leasing us free space on the busies social media intersection. Our goal is to capture as many of those people and take them home. Now that Facebook is starting to charge a little rent for business to reach fans, it’s even more important to focus on your website and how to get people to it. Thanks for sharing

  7. Thanks for these files. I’m having problems getting a bootable drive created. I have only windows 10 machines plus the machine that I just tried to install Windows Server Essentials 2016 on. (Only to find that while it recognizes the network, it thinks it’s disconnected.)

    Does anyone have suggestion on how to format a USB drive and copy the flat files so that it can boot?

    1. I found a Windows Server Essentials 2012 server that was up and running and was able to get my 2GB usb drive to work with this.

    2. I had this issue too so I used Rufus to create a bootable USB flash drive (FreeDos). Then copied the files across to the drive.
      Booted to the Rufus based DOS, then just ran the flash.bat and all went well.

      p.s. you can repair any USB drives damaged via diskpart, need to clean and create partition again, format.

  8. I Also had issues running the HPQUSB.exe tool on Windows 10 and Server 2012 R2. It did however work when I right clicked the exe and chose to “Run as Administrator” Hope that helps.

  9. Just perfect!
    I was so scared when the NIC would not respond, after I upgraded from Windows server 2012 to Windows Server 2012 R2.
    I was about to install a separate NIC card, thank you so much!

    But next time I won’t go for an HP server, that policy is pretty unreasonable, it’s not like you’re upgrading to a non supported OS.

  10. I have a N36L, I have tried to update BIOS using this method. but I keep ending up with a command prompt.
    – Have I bricked it? Can you get new motherboards to fit in the N36L?
    Then when I tried to reinstall Win10 I now get a screen saying my PC/Device needs to be repaired.
    ‘The boot Data file doesn’t contain enough information for an operating system’
    ‘Error code: 0xc0000098’
    Is this related to my attempt at BIOS update or to do with my OS installation usb?

    1. Sounds like a bootrecord issue. Try re-creating the Windows installation media, for example with the Windows USB Media Creation Tool (from Microsoft).

      Good luck!

  11. Thanks, confirmed that using the patch posted above successfully flashed my N40L microserver, upgrade to windows 10 successful, although I had to uplug all drives except the system drive in order to install windows 10, unrelated error though. Thanks for the help!
