I have cross-flashed an IBM M5014 to LSI 9260-8i, But seen!
I will flashed about 10 firmwares from old to new with the known method written at this site!
1) megarec -writesbr 0 sbrempty.bin
2) megarec -writesbr 0 sbr9260.bin
3) megarec -cleanflash 0
4) reboot
5) megarec -m0flash 0 xxxxxlsi.rom
Seen that, only certain firmwares accept 9260 banner, some others not!
I have shorten the last 10 firmware versions:
0102 --> OK
0111 --> OK
0124 --> X
0139 --> OK
0151 --> OK
0154 --> OK
0167 --> OK
0189 --> OK
0205 --> X
0239 --> X
The one's OK accepted sbr9260.bin at the banner, and the initiation time at the start is short!
The X one's did not accepted sbr9260.bin, and initiation time was also long....
BUT, BUT, BUT, also WHAT!
The OK ones get very high write results at ATTO disk benchmark v3.05, very well, close to read speed! (Between 2~2,5GB after 512KB file sizes.)
The X one's get very very low write speeds, more than "20 times" lower!
==> So, be aware of this problem! <==
IBM original firmware is , not only slowly initializing disc's at the beginning, but also very low performing at write speeds!
I have left my card bios at the latest 0239 for that reason.
Note: I did not "do anything" at configuration screen, when testing the different build of bios'es above.
I was using 7 x Corsair GS 128 SSD's with Raid 0 configuration before trying bios'es.
Automatic configuration and no redundancy was chosen when building the Raid 0 set.
One more thing: I have tested the same Raid 0 configuration with a smilar LSI 9211-8i and Highpoint 2720SGL cards. They performed much better with Raid 0 configuration. More than 3GB with LSI 9211-8i, and nearly 3GB with Highpoint 2720SGL.
If you are serious at SSD Raid 0, those two cards perform better than 9260 variant!
