LSI 9211-8i flashed to IT mode.
1. Get sas2flash.efi, current IT firmware and current BIOS from LSI web site
2. Put those on ordinary USB flash drive, and plug USB flash drive into computer
3. Do not boot from flash drive, but select UEFI boot from boot selector, which is f11 on SuperMicros
4. Select USB drive; type "map" in UEFI boot to show drives; mine was fs0, so I typed "fs0:" at UEFI prompt
