I am looking for the latest version of the SATA controller driver for an XPS 435T with an Intel Core i7-940 processor running Windows 8.1.
(The chipset appears to be Intel 5520/5500/X58.)
I think the SATA controller corresponds to the Intel ICH10R lpc interface controller listed in Device Manager under system devices.
Is that the correct? I.e., is the ICH10R driver the SATA driver?
If so, where can I find the most recent version of that driver?
Normally, you would get these drivers through the site of the PC's manufacturer (i.e. Dell in this case); it is possible that the PC's BIOS is customized for some particular version of this software. If you want to go for it, the latest Intel drivers are available here Downloads for Intel® Rapid Storage Technology (Intel® RST).
Hope this helps,
