DO NOT FLASH YOUR 8438E ! http://www.europe.soundblaster.com/joinin/forums/thread.asp?thre=1191&foru=18&page=12 From storms posts:1 Idler I opened my 8438E after killing it with the samsung flash-software, and discovered that the used flash-EEprom is a AMIC-A29040 PLCC-32. After a long search on the internet I found the home-page of AMIC, which is : HTTP://www.amic.com.tw On this page is the specification of the used hardware present in PDF-format. After reading it, a whole lot suddenly was clear. It said the following: "Sector protection: A hardware method of protecting sectors to prevent any inadvertent program of erase the entire chip or any combination of designated sectors" So creative screwed us.
