I don't test yours modding bios, I find a solution on google: https://retrohelix.com/2012/09/how-to-fi...e-hp-computers/ ctrl+ f10 access to hiden menu, thanks for your time

@31101958 - Thanks for posting a solution for this, great to see your BIOS has that possibility.
If you get bored and test the BIOS I sent, please let me know outcome so I can make a note of success/failure in my BIOS folder for this model, thanks

Also, so, once you enter this hidden area via that method you linked, were both fan check options set to enabled, or disabled?

Sorry, i don' posted the goods images,
For your's bios i test later and send a response too you for your time
the both fan was enabled

@31101958 - Thanks! Funny to see both "Enabled", but when you look in AMIBCP, both fail safe and optimized default show it as disabled.

testing this afternoon!

@31101958 - Thanks - Hopefully one will work! I checked both USB submenu that is visible to you, and the Hardware Monitor that isn't, and both were set to "show menu + Access Level = Reserved"
Based on that, I assumed both should be visible to you, or not, but something else must be what is controlling the hidden or visible, probably whatever is checked about "Reserved"
So I checked the hardware monitor to Show menu + User and Show Menu + Supervisor, I think one should make it appear for you by default, hopefully

I've testing your both bios, don't work fine but when in my original bios with CTRL+F10 i've entire access.

@31101958 - Thanks for testing, so neither one show Hardware Monitor by default visible? If not, OK, bummer, I will make a note of it that method fails for this BIOS
At least you can CTRL+F10 - Good find for this old BIOS

Never show hardware monitor, sorry for your work !!!!
See you later.
