Lacking STANDARDIZED firmware features

[jermahu]

I’m getting increasingly frustrated with OEM firmware lockouts on gaming PCs.

My system has:

• UEFI enabled
• modern CPU/chipset
• a ReBAR-capable GPU: rtx3080
• BIOS installed AMI F.25
• HP OMEN 30L motherboard 8703

Yet HP/OEM firmware removes or hides the advanced PCIe settings required to enable Resizable BAR / Above 4G Decoding.

This is industry-standard functionality supported by the hardware I paid for. Retail motherboards expose these options. OEM customers are stuck with artificially restricted firmware and no official way to access features their hardware is fully capable of using.

What’s most frustrating is that:

• there’s little transparency about whether support exists internally. Not a single decent response in over 7 years.
• BIOS menus are stripped down with no advanced mode
• users are pushed toward risky unofficial BIOS mods just to access standard functionality

Why are customers paying full price for capable hardware while being denied firmware-level access that exists on equivalent retail platforms?

At minimum, OEM vendors should:

• expose advanced BIOS options
• clearly document feature support/limitations
• provide official ReBAR support where the platform hardware already supports it

And from a technical standpoint: what is the actual engineering or validation reason this is still locked down in 2026, despite the feature being standardized across modern GPUs and chipsets? 

How has HP still not addressed these issues? Last time I checked was in 2019. That's 7 years ago. Are customers not taken serious at all?

Most, if not all, OEM PCs have limited BIOS options to reduce warranty support.

The only way to get full BIOS control is to purchase a System Integrator custom built PC using off the shelf components (which still carries a limited warranty) or you build the PC using retail parts.

All retail MB and other component manufacturers will void the warranty if post RMA inspection discovers MB damage or other component damage due to user error.

Look, your point on having access to all BIOS settings is valid. That's why I build my own PCs.

But I also realize I'm at financial risk if I break something.
