z420 bios error 110 out of memory space for option roms

HP Recommended
Microsoft Windows 10 (64-bit)

I put a extra SATA disk in the computer and now I get this error on startup.

When I google I find :

I know that under the Setup Menu/Advanced/Power On Options you are supposed to set the ACPI/USB Buffers @ Top of Memory setting to Enable, but unfortunately my version of BIOS doesn't contain this option.


I upgraded my bios and I still don't have that option


When I am in windows I can use my extra disk so I don't know what can solve this error

add in cards that have onboard bios roms require a specific sized amount of free space within the computer's main bios memory map HP systems are known for being limited in this free space


if you don't need to boot from his add in sata card, go into the z420 bios and DISABLE OPTION ROM LOADING for the pci-e slot the sata card is in doing this tells the system not to try loading the sata cards bios extension


if you do need to boot from this card. you can try disabling the z420's onboard network boot option and rom (2 different settings)
