What is PIO PPE?

#1

Can someone check the log below and tell me if everything is ok. I just replaced my cable to an 80 and installed the lastest Intel AA to make sure Ultra DMA Mode was enabled, but I see something about PIO PPE Enabled. What is PIO PPE, and will that conflict with the Ultra DMA mode?

Thanks for your help…this is all new to me.

I don’t know what PIO PPE is.
I do Know that PIO was the data transfer standard before we had DMA.

The most important thing here is the Current Transfer Mode, and that is set to DMA 4 so no worries there :slight_smile:

PIO is an acronym for Programmed Input Output

I have not heard of PPE before. PI/O is a necessary way to allow the computer to communicate to the disk. It uses this for command and control. The PIO is what allows the computer to initiate the DMA transfer. (DMA is Direct Memory Access).

I doubt that setting has anything to do with the problems you are having, assuming you are still having trouble.
