ATA (PI) 80Pin Cable Detection
Possible values of an option:
[Host AND Device], [Host], [Device]
The option description:
The rarely enough meeting option, allowing to select a procedure for test of type of an IDE-cable (40 or 80-zhilnyj). At value [Host and Device] the cable will be checked both from the motherboard, and from the drive, at [Host] — only from the motherboard, [Device] — only from the drive. In order to avoid possible damage of the data (usage of the rejected loop, the departed contacts on a connector) always is recommended to expose the first value.
For normal functioning of modes Ultra DMA 66 also it is above necessary 80-zhilnyj an IDE-cable with additional lines of grounding. If the motherboard finds out that the drive is connected "old" 40-zhilnym by cable, as much as possible accessible mode of an exchange will be reduced to Ultra DMA 33, distortion of the data differently is possible during an exchange.
