PCDVD數位科技討論區 - 有關amd sb710 port multiplier 的問題

在Catalyst 14.9的SB Driver解壓縮後Drivers\SBDrv\SB7xx\AHCI\W764A內有一個Release_Public文件，內容有這麼一段(底線是弟加的)：

Implementation Notes

The amdsata driver package provides Port Multiplier support, but because of Port Multiplier HW inconsistency and boot timing negative impact it is enabled on eSATA ports only.
This makes impossible a scenario when OS needs to be installed using devices behind a Port Multiplier; to enable OS installation using devices behind a Port Multiplier, Port Multiplier support needs to be enabled in the inf file and OS(Win7) distribution media needs to be updated w/ the Port Multiplier support enabled driver; BIOS support for Port Multiplier is required as well.
See the OEM.doc for details on the inf file settings.

以弟破破的英文與參照Google翻譯，關鍵就第一節，因為Multiplier會增加開機時間，
於是設計成只有在eSATA模式下才能啟用，
所以這可能要看你的主機版有沒有把SATA設定成eSATA或熱拔插的選項吧？
