When I look at the WIndows 95 Device Manager, I see one strange device in the list:
"IO read data port for ISA Plug and Play enumerator"

1336-Weird Windows 95 autodetected hardware.jpg

It seems to have some weird port ranges in it's I/O list:
1337-Unknown IO ports 1.jpg
1338-Unknown IO ports 2.jpg

Range 270h-273h, 370h-373h, 338h-33Bh and 238-23Bh?

Anyone has any idea what this is? I have normal ISA PNP emulated at ports CF8-CFF, but that is another item and not even mentioned in said item?

I don't think it is weird. I think it is something for PnP ISA cards. I also get many such weird IO devices my WIN98 machine. Don't worry about it, and neither un- install it

Do you mean it's some interface to some PnP driver? Because no such I/O ports exist on the physical machine. All those I/O ports are unmapped(won't write anything and reads float the bus). So is Windows using the CPU's port I/O trapping to redirect it to some virtual driver that emulates those ports?

Installing Chipset drivers might change it to a frendlier name.

So those ports aren't actually physical ports on the machine? Instead they're something the interface uses(using the I/O port trapping of the CPU) to communicate with software, emulating the device as a compatiblity layer for software not implementing the PnP that's used by the actual real(in UniPCemu/Bochs/Dosbox's case emulated PnP ports) hardware? Because those ports it mentions in the auto configuration setting aren't actually present on the I/O ports of the CPU(It uses ports CF8-CFFh instead)?
