.PoNeH, first of all to answer you question. Run even the lightest free version of Sisoft Sandra, Everest, or Belarc Advisor. (Sandra lists and tests hardware limits of your machine) (Belarc tests nothing but you will know all that is installed hard and soft) I see your M90 feature set as having Sound Blaster Audigy HD So if that is correct you've either got a Creative/Emu (Sound Blaster) chip but more likely a Sigmatel with what is known as Sound Blaster Audigy Software HD. If you go to bottom right and right click on a little blue speaker icon and see a pop up menu with Creative Media Source selections, EAX,Graffic EQ, etc. then you have the software already. If not and you want it Dell will sell it to you and they will be able to say for sure if it will work for M90. ......I just checked Dells web site even dld M90 tech PDF. It certainly is an as kickin machine but you'd think they would tell us something more about the sound than it has a mike input and a headphone/ line out jack. For this it is a very safe bet that you have a Sigmatel 9200. If it were 9220 we'd see more inputs and outputs. Good listening to yah.
