Dell HBA330 -> H330 recover Crossflash

Hey Guys,

I’ve got a R230 Server with a H330 Controller flashed to HBA330. Is there a way to recover/reflash it to the Original H330 RAID Firmware?
I think it’s doable, but i can’t find the original Dell Perc H330 Firmware and Bios files.

That entire line of '330 cards are just a Dell rebrand of the LSI\Avago\Broadcom 9300 series cards, even down to the Dell External SAS HBA. The most compatible and usable version for TrueNAS is the HBA330. Unless you have a very specific reason for needing RAID functionality, I would strongly suggest leaving it as an HBA330.
