There is a possibility that your dvd-rom is not the one mentioned above, please go to http://perso.club-internet.fr/farzeno/firmware/ and download "DriveRegionInfo" to check your dvd-rom again. We'll see what happens after that.:)
P.S.: And also please give me detailed information about your dvd-rom drive.

型號是acer 1648A
目前韌體是1.02
REGION:1
USER:3 CHANGES LEFT
MANUFACTURE:4 CHANGES LEFT
STATUS:NOT PERMANENT

The only patched firmware I found was the one I attached before......What version of windows you're using?

我的OS是98二版，
我之前也是執行那UPW9X的檔案，
但卻會出現surported drive not found的訊息。

Then I don't have any ideas about it .......sorry.

別這麼說，
您也十分熱心，
令我非常感激，
只能怪我買了爛機器了！
