IDE設備一般是有master跟slave(主-從)之分
而薄型光碟設備,有些會在表面有小小的開關
有些則是隱藏

從SONY NEC官網資料得知(以下)
IDE Changing Tool (changing the Master/Slave mode)

In case your laptop does not recognise the device in the BIOS and/or operatingsystem, you need to get a little tool which changes the mode (master/slave) of your drive. Often recognised with Toshiba and/or IBM notebooks.

Please write an email with a short problem description and the model name to the below mentioned address. We will send you the appropriate tool via email as soon as possible.

HINT: This tool can only be used for SlimLine (Laptop) devices and not for Half Height drives.



以上寫到
特別是Toshiba and IBM常有這個問題
這裡的 little tool (小工具)應該是軟體
因為他提到他會把小工具eMAIL給你
你可以寫信去問問看


搞不好得從韌體去改寫也說不定
