I've had the ASRock C2750D4I for quite some time now and after some BMC (AMI MegaRAC) and UEFI updates the remote control Java applet finally works. My biggest problem with the applet is that it doesn't capture the ALT key, I have to click ALT in the applet to be able to type certain characters. I have a Swedish keyboard and we have lots of special characters hidden away in the 1-9 keys and beyond, on the keyboard.
I wish to be able to access the IPMI Remote Control features with a piece of software that captures ALT properly.
Characters that are hidden behind ALT for me: @£${[]}\~|µ€
Well if its a VNC java applet (Proxmox used to do something like this until they switched to NoVNC) then you SHOULD be able to use a normal desktop VNC client to connect. I don't know if that'll work but you might try it...
The keymap is set up correctly. It works just fine in other Java applications. The only keyboard availible in Windows is the Swedish layout.
This is really driving me nuts! I don't think that the latest BMC software has the latest version of the applet (it's 1.114.0 and "plugin version 1.0.10 for AST" what ever that means.
That's the same version I have and the F keys work fine. I can't test alt codes, but from what I can tell alt isn't getting passed through to the client.
I can't type ÅÄÖ either, which are Swedish letters. When I press a special character key then I get Ä and if I use backspace then I'll go back twice per character. So I figured out that the applet sent UTF-8 characters so I changed the system LANG to sv_SE.utf8 which fixes that issue.
F1-F12 works just fine outside of Linux so I don't get what the problem is. I've set the keymap to sv-latin1 which is the only Swedish keyboard standard.
Nothing happens when I mount an ISO in the applet either. No reaction from the OS or from the UEFI/BIOS. Does this function work for you? The machine doesn't have a CD/DVD drive.
