My Pc's IDE channels settings were DMA until today when I upgraded the firmware on my Samsung TS_H552b. When I installed the new update I had to restart my computer. I then had new hardware found, new drivers installed come up. I then checked my IDE controller and it had been set back to PIO mode. What I want to know is: If I uninstall the IDE channel so that I can change back to DMA mode will this remove my firmware upgrade? I hope this makes sense....Is there a way I can check what version of my firmware upgrade I have???
