Intel RST driver 12.6.0.1033 not saving cache mode

I've tested this with version 12.5.0.1066 and the latest 12.6.0.1033 for windows 8, the system has the express chipset

when I restart my system, the RAID array performance settings are reverting back to a default mode with:

- write-cache buffer flushing: enabled

- cache mode: none

when I have set the system for:

- write-cache buffer flushing: disabled

- cache mode: write back

after rebooting the system defaults (as noted above), I have to open the RST application, disabled flushing and re-enabled the cache mode... otherwise performance is terrible...

is there a workaround to this, or something in the registry that needs to be cleared or modified?

thanks!
