In this video I walk through my exact firmware update procedure for an LSI 9207-8e SAS HBA, flashing it to P20 IT mode. The 9207-8e is a PCIe Gen 3 card with two external ports, and it can support a huge number of SAS/SATA endpoints. I’ve used the LSI 9200 series a lot (rock solid), but the 9207 gives you nearly double the PCIe bandwidth, so it’s a great upgrade for big storage and homelab servers. I start by grabbing the correct firmware package from Broadcom’s knowledge base (Broadcom owns LSI now). I also explain the difference between IT mode (pass-through/JBOD) and IR mode (integrated RAID), and why I’m typically after IT mode these days. From there I build a simple FreeDOS boot USB, copy over the DOS version of sas2flash plus the firmware files, and then boot the server in Legacy/BIOS mode to keep the flashing process painless. Once I’m in DOS, I show the commands I use: list the controller, erase the flash with erase mode 6, and then flash the P20 firmware (optionally the BIOS ROM, which I skip to avoid extra boot delays). At the end, I verify the firmware version updated successfully—straightforward once you know the process and keep the reference guide handy.
