Resizable BAR on SuperMicro H11SSL-I with Intel Arc B580

Resizable BAR on SuperMicro H11SSL-I with Intel Arc B580

This might work other mainboards and graphic adapters as well, but this article assumes H11SSL and B580.

The Issue

The SuperMicro H11SSL-I board does not have an option in the BIOS to enable "Resizable BAR" (Base Address Register), aka "Smart Access Memory" (SAM) for AMD Platforms. It was not introduced until the H12 series boards.

UEFI hacks is possible using https://github.com/xCuri0/ReBarUEFI, but this is difficult, risky, requires flashing firmware and even maybe use of a chip programmer.

KlipperScreen Splash Screen Video

KlipperScreen Splash Screen Video

A simple systemd service to show a splash video before KlipperScreen loads.

Demo: https://www.youtube.com/watch?v=En1gtl8IiC8

Note:

This interrupts the launch of KlipperScreen. However the other Klipper services still start up in the background, so it's not really noticable in terms of total startup time.

Klipper piezo buzzer configuration (M300)

I wanted to connect a simple piezo buzzer to my 3D-printer running Klipper to make some beeps when a print starts, stops, etc.

Parts required

  • A passive buzzer (I bought these cheap ones from Ali)
    • Note that active buzzers have an internal oscillator and cannot emit tones of different frequencies.
  • Some wires and a connector

Assembly
