The current mfi driver does not support configuration changes.

Is there a way you can make it so that the driver can change the configuration from inside OSX? Windows doesn't really boot reliably in this system, and I'd really like to not have Windows installed just to be a drive controller manager. And the BIOS configuration tool can't be invoked during boot to a BIOS based OS. This has always been an issue, just wishing it could be fixed. FWIW running macOS 10.13.4 at this point in time. 17.5.0 Darwin Kernel Version 17.5.0: Mon Mar 5 22:24:32 PST 2018; root:xnu-4570.51.1~1/RELEASE_X86_64 x86_64

@eweiman

Unfortuntately I can't, I don't use Macs anymore. But patches from other people are welcome though.

[eweiman]

Thanks for the quick reply. I'm not sure where to begin to do it or if it was even feasible. As such, I'll close this out and if in the future someone knows they could re-open / comment.

@eweiman You should look at mfiutil source code, https://github.com/freebsd/freebsd/tree/master/usr.sbin/mfiutil particulary starting from https://github.com/freebsd/freebsd/blob/master/usr.sbin/mfiutil/mfi_cmd.c#L206 and also mfi driver https://github.com/freebsd/freebsd/tree/master/sys/dev/mfi Note that mfi driver and SASMegaRAID driver are different, so blind copy & paste will not work.
