Hello, have you tried reflashing the BIOS to a different rev to see if the option you want is in one of those?

Also, have you tried to boot OS X without having that option available? You might be able to get it working without it. Hope it helps :)

If you have boot options that include USB HDD support try installing to an external drive from a VM or using OSXModCD on the machine.

620 MT wasn't listed in Dell's support pages but I assume that just is another flavor of the 620 itself, so yeah, here you go. Download A02 or A00 of the BIOS rev listed on this page and run it from a Windows installation to install it. They should be pretty self-explanatory and have easy to follow instructions.

Once again, you need to have a Windows installation to be able to run and use these files. There exists threads and topics about how to reflash a BIOS using different operating systems such as Mac, or Linux but I don't recommend that. Those topics are for advanced users and can be dangerous to play around with. These files were designed to be run using Windows and that's the route you should go with. If you don't have Windows installed, install it first. Good luck.

How to patch Dell Bios to enable AHCI

First of all...
The H61 chipset is perfectly capable of doing AHCI.
It's a Dell choice to put the H61 chipset in IDE Compatible Mode only

Here's how you can enable it:

- grab the latest bios. (.exe) from dell support.

- launch the .exe and do not close the flash windows app. Grab all the file from the %TEMP%\randomname subfolder

- Get AmiBcp tool.( AMI bios hacking tool)

- Load MS-Axx.bin from within AmiBCP.
Modify the entry to make the SATA menu available (change from default to USER)
Modify SATA controller menu (change from default to USER) and (from IDE to AHCI option) and ( from compatible to enhanced)

- Flash. Now you have enabled AHCI and you can choose from IDE to AHCI entering in F2 bios setp ....

- Enjoy.

Best Regards
