小弟也是用DELL OEM 的XM，
目前使用PAX PCI XFI All-OS-Driver V1.15的驅動，
已經解決關機延遲的問題，
但是DTS跟DDL一樣都還是不能開，
只有前任驅動維護者Youp知道該怎麼在driver開啟，
現任的維護者Robert McClelland在論壇有說：
Sorry I don't know how Make the Decorder tabs to work in 3.63 set. Only
Youp would know. I don't If you really want DDL and DTS just go buy them
at Creative Labs.
所以目前只要是用DELL OEM沒刷firmware的想解DTS跟DDL應該還是無解....
