效能低落。可以嘗試裝Orange Ware 的 Ti 1394B driver

以及 M$ KB88522 修正

抓不到硬碟，我覺得很有可能是1394B 線有問題
不妨買一條 1394 6pin-9pin 線，交叉測試。

感謝各路高手熱情指教,剛剛小弟問過同事,他說,你知不知道1394b的卡上有一個4Pin的電源接頭,小弟說:啥! :eek: :eek: :eek:

對喔!小弟印象中是有個白色不知道幹嘛的東西在卡的邊邊,哇咧,該不會就是因為沒插上,電力不足,抓不到硬碟???

可是小弟現在人在公司,卡放在家裡,要回去試試才知道,如果成功了再向各位回報. :yeah:

謝謝提供1394b的driver,小弟用google有查到這個驅動程式,據說可以大大提高傳輸效能,但沒找到地方下載,感謝提供. :p

Support 剛回我的 EMAIL

Dear Tommy,

Good day,

Yes, your motherboard PCI was 32 bit, it just show 1394A.

If you using 64bit framework, the system will recognize 1394B.

Thanks.

Best Regards

Stanley

所附圖片是在1394b卡在32bit PCI下，接HDD所跑出來的

這兩天在下也會去問廠商這問題

阿湯哥那邊也有一個1394B的測試
我記得也是用PCI32去測的...

這篇文章應該足以證明在32bit PCI下，1394b卡並未降格為1394a(S400)

會降為1394a應該是ガセビア

Century Global has made ample provision, equipping the card with a 64 bit wide PCI interface. With 800 Mbps (or 100 MB/s when converted), 1394b just about reaches the limit as to which the PCI bus is capable of with the usual 32 bit and 33 MHz. In theory, this is up to 132 MB/s, in practice, however, this suffers due to the fact that the bus is used equally by all the connected devices. A sound card, the USB controller (mouse, keyboard, web cam, printer, scanner), a TV or video editing card - all of these gobble up bandwidth. The theoretical maximum rate is only attained in isolated cases.

那報導我也貼了，難道您覺得這整篇測試還不能證明
在32bit PCI下，1394b卡並未降格為1394a(S400)嗎?
