Downgrade LSI 9207 to P19 Firmware

After numerous problems encountered with the P20 firmware on this card model, here are the steps I followed to flash in P19 Version.

Since, no more problems :)

The model of the card is a LSI 9207-8i (SAS2308 controler) with IT FW:

lspci | grep LSI
01:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS2308 PCI-Express Fusion-MPT SAS-2 (rev 05)

I use :

With VFD I create an new 2.88 MB floppy that contain :

KERNEL.SYS     from Freedos
sys.com        from Freedos
sas2flash.efi  from Installer P20 for UEFI
mptsas2.rom    from 9207_8i_Package_P19_IR_IT_Firmware_BIOS_for_MSDOS_Windows
9207-8.bin     from 9207_8i_Package_P19_IR_IT_Firmware_BIOS_for_MSDOS_Windows (IT firmware in my case)

Virtual Storage plugin on Supermicro to connect Drive B :

Reboot server and press F11 on startup to access boot menu and start with Built-in EFI Shell.

Go into floppy drive (fs0:, or fs1:, fs2:, …) and verify content :

Before starting to flash, verify your card with sas2flash -list. If you have more than one controler you can specify the controler with -c controler_id for the next commands.

Next, you will need to erase all the content of the card (to avoid error like “Cannot downgrade NVDATA version…”)

sas2flash -o -e 6

Flash with the new firmware and bios :

sas2flash -f 9207-8.bin -b mptsas2.rom

Verify the new firmware version :
