I have been trying for 3 days to flash a DELL 6/iR with no luck. SASFLASH from the LSI support site was no help at all. My fingers have blisters from GOOGLEing for help. I'm so glad I found this thread!
Burned a 2G USB stick with RUFUS 2.2/FreeDOS. I was getting an error saying SASFLASH could not run in DOS mode.
After downloading the zip files here, I found that sasflash-1.24.exe ran without the above mentioned error on my flash stick.
Dell PowerEdge R200 with the 6/iR HBA flashed without any problems. I made some mods to the batch files to shorten the file names and to run sasflash-1.24.exe and all is good.
Thanks for the work!!!
