Re: UEFI Bios

I'm interested in this now. Does using UEFI change the Pi in any way? Or is it just a bootloader that is loaded by the device firmware during every boot and only into memory before the operating system?

Re: Focusrite Scarlett 6i6 with 32-bit Buster

One thing to understand when one starts tinkering around in alsamixer : Even though many of the sliders appear to be at +0dB position, they are in fact muted. You need to "touch" them, that is, move them back and forth once. So you basically begin with a system that has everything muted, b...

Focusrite Scarlett 6i6 with 32-bit Buster

Hello I am trying to make a Focusrite Scarlett 6i6 sound module output two channels to a normal stereo system, especially from Firefox, but also from mpv when watching movies. I gather that Firefox needs Pulseaudio, but for mpv it is possible to use either ALSA or Pulseaudio. The output of aplay -l ...

Re: Wifi connection unstable

I fixed this for my Pi 3 B by disabling Wireless Multimedia Extensions (WMM) in my router. Those contain some power saving feature that, if it suddenly turns on, will halt all traffic. I'm running a minimal installation of Raspbian Buster. It'd be good to be able to use the Pi in a WMM enabled netwo...

Re: [SOLVED]How to remove the raspberry logo during boot

Is it possible to remove the logos after Raspbian has booted? I am not using graphical login and I seem to have only one virtual terminal.

I realized that running raspi-config and immediately quitting does it. But stty sane or pressing Ctrl-l do not.

Re: Memory Bandwidth of the Pi 4B

I think it's very simply that in those Ryzen systems, the limiting factor is a resource that is shared among the cores, with the sharing causing little or no side effects. In Pi 4B there is some shared resource with which the sharing causes a side effect. Of a limited magnitude, it seems. I'd guess ...

Are there any small and inexpensive computers at all with ECC memory?

Was there a NAS project once somewhere that did have that?

Or did they have it just basically and theoretically but nobody was sure if they really had that, or at least there was no way to verify?

And this happens constantly. There are even parts of the level missing. Reducing the resolution doesn't help. Increasing the GPU/RAM split to 256 MB doesn't help. This is 1920x1080 though.

Re: Raspbian Buster uses old version of youtube-dl that cannot download anything

youtube-dl has its own, internal update mechanism. You simply invoke it with youtube-dl -U.

Of course you need to run it as a user who has write permissions to the executable. I have it in my home folder in a subdirectory.

I'd assume the GUI is not reporting anything per se, but is simply made to ignore enterprise networks.

Question is, do I lose anything (in compatibility, security, availability, performance) by switcing the driver?
