Is there a way to switch this model to run in AHCI mode instead of sata/ide? I have installed a transcend ssd (ide), and installed windows 7, but it is recommended to be installed in ahci mode. I cannot find it in the BIOS. If anyone has information or has done this before, any information would be greatly appreciated.
The Inspiron's Intel 865 chipset supports SATA/AHCI, however, as SATA was just coming online when the 9100 was released, it is unlikely that a low-end line, like the Inspiron, would have been given the time, resources, and attention necessary to implement full Dell support for SATA/AHCI, which is likely why it is missing from the BIOS. About your only chance would be to make sure the BIOS is up to date - if the option was not originally available and was later added, it would have been added by way of a BIOS update. However, none of the release notes for any of the BIOS updates say anything about adding this functionality. I'd say your 9100, at around 8 years of age, is just too old.
