USB keyboard fast key repeat and crash at boot

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,
I've just bought an B450M Pro4-F with BIOS 1.60 using a Ryzen 5 3600.
I tried to PXE boot to configure the PC but pressing a key on the keyboard gives really fast key repeat and locks up after a few seconds.
I can also get the motherboard to lock up if I press any key for even a short time during boot. eg Esc/Del/F11

I managed to work around it using a PS2 keyboard.
Also once in Linux the USB keyboard worked fine.

Is there any settings I might have missed that might fix it?

Regards
Spiff

	Asrock support suggested I try the Beta 1.97 BIOS which seems to have fixed it.
