Visit the following links: The dmesg output shows repeated error messages such as “Disabling IRQ Indicates that the secondary controller supports both legacy and native modes. Sat Oct 23, 9: As CPU speeds increased, a bottleneck eventually emerged between the processor and the motherboarddue to limitations caused by data transmission between the CPU and southbridge.
Intel ICH5 SATA Controller PRM
We appreciate your patience and understanding as we make this transition. Figure 1 illustrates this configuration: Accordingly, starting with the Intel 5 Seriesa new architecture was used that incorporated some functions of the traditional north and south bridge chips onto the CPU itself, with the remaining functions being consolidated into a single Platform Controller Hub PCH.
When set, the port is enabled. Operating system software requiring legacy only mode capability is required to find the SATA host controller configured for compatible mode.
The exact value programmed into this register is based on a BIOS setup option. These two items can be determined by software in succession detect for device, then check readiness or simultaneously safa for readiness, as a ready device must be present. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Current characterized errata are available on request. Unfortunately the install is not seeing my disk. In this configuration, software reads and writes to the slave device registers will result in a master abort and as such reading from the slave device registers will return all 1.
The most important innovation was the support of USB 2. It would be helpful if you could test the upcoming release and verify if this is still an issue – http: How system software handles cih5 swapping is very dependent on the target platform.
The flexibility of the mapping register also allows the following configuration:
