Hey, regarding the really obvious stuff like PCI cards...
I once unplugged a NCR/Symbios Logic SCSI-controller from a running system.
And plugged it back in very carefully after a while.
While running graphically under NetBSD with 1.5GB Virtual Channel Memory. (Slightly better SD-RAM, only supported by some chipsets)
Monitor went ZONK, because NetBSD switched to text-mode console, which 21" Supersync barely supported, spewed endless alerts, after alerts.
After replugging something like found controller, resetting, found disk(s), resetting, alerts gone, switching back to X.
Magic.
Didn't even have filesystem errors, which I checked for after that stunt.
Which btw. didn't work with an Adaptec2940 fast and wide.
Nor Linux, in whichever config.
Some hot plugging, eh? :-)
- anyfoo 4y agoHeh, amazing. I love when stuff like this "works out".
- toast0 4y agoPCI could be hot-pluggable actually. It requires a lot of fiddly bits though. Especially, you need to setup enough address space for the cards without knowing what they are.
- LargoLasskhyfv 4y agoI think this is actually the reason why you can only use 3 GB of 4GB on some older Thinkpads. Because docking, and such, they took care of that.
