Cards have been tested and updated to version 16.00.12.00 IT mode firmware.
This is a newer version of firmware than is available on Broadcom's site. It addresses issues caused in previous versions when using SATA drives in TrueNAS.
Prior to updating, the cards are wiped clean (with the exception of the manufacturing area) and the updates are performed from EFI Shell. This is the most thorough way to update these cards. We have previously seen issues for users of LSI HBAs in Windows 10 if the cards were not wiped prior to updating, and if the updates were not performed in EFI Shell or DOS.
Firmware has been updated to version 16.00.12.00.

x64 BIOS (signed) has been updated to version 18.00.00.00.
