Dell XPS420

[trase2482]

Has anyone tried installing Mavericks on a Dell XPS 420?

Intel Core2Duo Q6600 Processor
Nvidia GeForce 560Ti
4GB 800MHz DDR2
Intel X38 (Bearlake) Motherboard
Intel® 7.1 channel High Definition Integrated Audio

I'm able to boot into the installer after removing the Nvidia kexts with -v -x GraphicsEnabler=No, but there doesn't appear to be an option for AHCI and neither my SSD or SATA drive shows up under Disk utility.

In the off-chance it helps anyone else, I found this DSDT in another forum:

With this loaded, the internal drives show up and allow installation and the built-in networking is working.

Did you try to update your firmware to A07, even if you are already in A07 ?

Worked for me, as my A07 version was from 02/2011, and the one from dell.com was from 05/2011
