Disable bios on H220 LSI SAS2308

[placedusoleil]

I would like to diasable bios on H220 LSI SAS2308.
Is it possible to do it with sas2flash? If so, how?

I believe you'd have to use megarec and run -cleanflash on the adapter and then use sas2flash without the -b flag. Basically, the following:

Code:

megarec -writesbr 0 backupfile.bin
megarec -cleanflash 0

<reboot>

sas2flsh -o -f <firmware image>
sas2flsh -o -sasadd <sas address>

Boot from FreeDOS on a USB drive so FreeNAS isn't using the cards. Here's details on the process (for a different version LSI controller, but same idea): https://www.servethehome.com/ibm-serveraid-m1015-part-4/

To disable the BIOS you can go into the firmware and choose the card (it'll say "enabled" on the right), then set Boot Support to none. You still get the BIOS screen at boot but it won't offer any drives to the system as bootable.
