No. That was a request for you to tell us why, give us a scenario, plugging in a pci device could fry the harware. What is it about plugging in the device that makes it dangerous. Otherwise I could claim that if you think about elephants while you open Libreoffice it can crash and wipe out the whole operating system. When you tell me you have often thought of elephants while opening libreoffice, I give a rant like yours above. I want an explanation of how unplugging or plugging in a PCI mouse or keyboard could fry the hardware in the computer. keyboards and mice do NOT have large inductors in them, so that theory of transient voltage spikes from rapid inductor charging seems pretty far fetched to me. So give me a theory. The second part was the claim that PCI keyboards and mice are not hotpluggable. Since it worked as a hot pluggable device for me, one counterexample is sufficient to disprove a universal theorem. > > The electrical and mechanical characteristics of the PS/2 port are not > design for hot-plugging.

Why they delude themselves into believing this is beyond my ability to comprehend. Usenet will always be here. Longer than people remember what port 80 was for.

Well, come over and explain that to my computer, then. The other day, I
was tidying up the cables at the back a little, and I had inadvertently
dislodged the mouse cable from its PS/2 port. It was still plugged in,
but not all the way. After booting up the machine, I noticed the mouse
wasn't working, so I reached out behind the computer chassis and pushed
the mouse plug back into place. After another reboot, the mouse wasn't
working at all anymore.
I removed the adapter plug from the mouse cable ─ it's actually a USB
mouse with a PS/2 adapter plug on it ─ and plugged it into a USB port.
Mouse worked again, no configuration needed ─ thanks to evdev.
The bottom line is this: you can get away with hot-(un)plugging a PS/2
port a couple of times, but if you do get away with it, then you're
simply extremely lucky. It's like playing Russian Roulette. PS/2
connectors were not designed for that, and you can (and will) blow them
up at some time if you keep doing this.
If you want hot-plugging, use the USB connectors. That's what they were
designed for.

I send my messages with the ISO-8859-15 charset. Kenny's newsreader quoted it without indicating any charset. William's newseader reacted legitimately when receiving a non-ASCII character without any defined charset.

Just guessing but maybe you have changed your BIOS/UEFI settings so that only "OS keyboards" (or something) are supported and not "BIOS mode" support. Different settings probably name them differently but usually there are such settings.

UEFI use F8 to give the Boot order (or F9) Ie, do not assume. Also sometimes you need to be sitting there hitting the appropriate key many times as it is booting up. > Helge
