Core Ultra FW13's Pre-boot External Screen Output, and Other BIOS Options

Hello folks,

My 12th Gen initially does not send anything to external display before OS loads, when the laptop is complete with the internal eDP screen present. To my amazement, the 3.08 BIOS enabled this feature, which is very convenient for me and a feature I’m no longer willing to live without.

Last time I tried with AMD13, I can confirm it doesn’t have this feature (3.05 BIOS). Unsure about 11th and 13th Gen, haven’t got my hands on them.

I’ve been considering to potentially upgrade to the Core Ultra generation later, but it will need to have this feature. @Wio_Steelhor , I just saw you with your new Core Ultra FW13 on a different topic. If you have an external display handy, would you mind trying if BIOS and other pre-OS interfaces can be shown externally? Other friends here are also welcome to chime in :slight_smile:

(Also curious to know if the Core Ultra FW13 generation supports iGPU RAM allocation, CPU core management, and any other advanced settings. Seems like BIOS options on this generation is not yet well-documented)

Correct me if I’m wrong, but I believe on Intel iGPUs they usually do not list any dedicated graphics amount only shared graphics memory. This shared memory is usually just half of the total system memory.

Here’s a screenshot of my Task Manager with Iris Xe Graphics. It may be different now though because the Intel Core Ultra series uses Arc Graphics.

Yup, you are exactly right. Iris Xe doesn’t have user allocatable iGPU RAM reserve, I’m curious if Arc integrated graphics changed this, especially since current AMD counterparts can do it.


Screenshot of the Core Ultra 7 155H. Same as before, half the total system memory even with an eGPU plugged in.
