Re: Non Plug & Play ISA Driver support in Windows XP and Windows 7 ?

> I need to write a driver for Non Plug & Play ISA supported CAN

I think PnP ISA drivers are the same as non-PnP ones, the difference is in INF file and installation only.

The INF for non-PnP must list the possible port IO ranges in LogConfig, the device is installed manually in Add New Hardware+select from list, and there the admin must choose the port IO ranges from the ones in LogConfig.

Yes, just do not touch the config space and remember that ISA interrupts are Latched and not LevelSensitive.

MmMapIoSpace is for memory-mapped IO, not for IO ports.

No.

To be proper, you should leave the PnP installer (which interprets your INF) to put these config values to some PnP registry.

Then your driver will get MJ_START_DEVICE with ..AllocatedResourcesTranslated, where you will see your port numbers. Save them to the devext and then use READ/WRITE_PORT_UCHAR/USHORT to access the hardware.

This is the proper way.

But yes, it will be the same address :-)

Register your interrupt as Latched.

Good Morning, I am receiving Microsoft internal emails on my home computer,
Why?
