Thanks for this post, it got me pointed in the right direction. I just want to add what I did to get my 9240-8i flashed on a Lenovo TS140. This will probably work on other systems that don't have a boot to efi shell boot option: use the first page of BetaQuasi's M1015 Cross flashing instructions as a guide create the bootable USB key as described grab the latest 9211-8i package from LSI's web site (as of this writing P19) replace the 2118it.bin and mptsas2.rom files on the USB key with the ones in the package you just downloaded create a directory structure \efi\boot\ on the USB key copy <usb>:\Shell_Full.efi to <usb>:\efi\boot\bootx64.efi set bios on system to uefi only boot from USB key the system should boot to the efi shell from the shell type fs0: to get to the root of the USB key were all the files are continue following the M1015 Cross flashing instructions
