Hello, 

I recently bought second hand hp Z840 workstation for my cad applications. As soon as I turned on the machine, the custom splash logo (from an organization) appeared instead of the hp logo that I expected. It is quite annoying for me. I tried so many ways to hide the current logo and show the original splash logo, but it hasn't been successful yet. I see a post on this hp community web page from this link

 https://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/HP-z-series-workst... .

Even though it was said an accepted solution, the DOS commands are not working when I tried. I updated Bios with latest version which came out in 2021. Can anybody help me out with this? May be I am not good at coding in DOS mode. Thanks.

@Nathan_Burma -- the DOS commands are not working when I tried

 

Character for character, what command did you enter?

Exactly what error-message was produced after you pressed ENTER ?

 

P.S. There seems to be at least one "typo" in that other discussion thread.  That does not help!

I started with change directory, so in the dos mode,

At the very first prompt, I failed. my USB boot name is drive I,

 so , I type C:\> cd I

and then it said, CHDIR failed for 'I'

Could you please point out the possible codes shown in other post? Thanks.

@Nathan_Burma --   At the very first prompt, I failed. my USB boot name is drive I,  

so , I type C:\> cd I

and then it said, CHDIR failed for 'I'

 

At the prompt, if you just press the ENTER key, you will see a "prompt", namely "C:\ >".

That is the prompt that tells you that your computer is ready to accept the next command.

So, just type:     I:     and press ENTER.

The prompt will change, namely to "I:\ >", to indicate that you are now working against the "I:" drive-letter.

Your next input could be something like   CD directory_name     followed by the ENTER key.

The next prompt becomes  "I:\directory_name  >", to indicate that you are now working in the "directory_name" folder on the "I:" drive-letter.

 

From the other thread:

 

          At DOS prompt, change directory to *:\DOSFlash (* is the Flash Drive root drive letter)

 

So, the commands you need to enter are:

  1. I:
  2. CD DOSFlash

in order for that folder on your USB device to become the current "working-folder".

In my computer, USB drive is known as Drive: I, but in the DOS mode when I type in I: as you said, I see the message 'Invalid drive I:.'. So can't go any further.

Hi, I got an error message saying that 'Clear-HPFirmwareBoot' Logo command was found in the module 'HP, Firmware, but the module could not be loaded.

HP Recommended

@Nathan_Burma -- I am guessing that when Windows is running, your USB stick is assigned as "I:".

 

But, when you boot from the USB stick, it is assigned a different drive-letter.

 

So, just experiment:

  1. Enter one "D", then one "colon"  (if I type the "D" followed by the "colon", this web-site changes the 2 characters to a "sad-face" emoji)
  2. Press Enter
  3. Enter DIR
  4. Press Enter
  5. If the "directory-listing" produced by the above DIR command shows some of the files on your USB stick, you have success.
  6. Otherwise, enter E:
  7. Repeat #2 through #5
  8. If no success, enter F:
  9. Repeat #2 through #5
  10. If no success, enter G:
  11. Repeat #2 through #5
  12. If no success, enter H:
  13. Repeat #2 through #5
  14. If you notice that there is a pattern to this madness, above, keep going all the way to entering Z:  --- or until you achieve success.

Good luck!

Yeah, It shows as drive C, a bit weird, when I type dir, it showed Directory of C:\ and all of my files in USB drive. But I can't change the directory to USB drive letter. I type as you mentioned earlier (CD DOSFlash), it doesn't work.

@Nathan_Burma -- when I type dir, it showed Directory of C:\ and all of my files in USB drive. But I can't change the directory to USB drive letter. 

 

It makes some sense that you see your USB files on "C:", because you booted from the USB.

 

When running Windows, insert the USB memory-stick. Persumably, it will become the "I" drive-letter.

View the folder-names in the "root-directory" of that drive-letter. 

Do you see a folder named "USBFlash" ?

If you do not see it while running Windows, you will not see it after booting from that USB memory-stick.

 

This implies that the instructions given in that other discussion-thread are not 100% accurate for your situation.
