text: <s>[INST] powerflex 40 firmware questions I have a powerflex 40 drive, 22B-D010N104BD. It has a non standard firmware and the OEM is no longer selling this drive. Is there anyway to get and flash the firmware to another drive of the same model? [/INST] I did not know custom firmware was an option, but your post made me look in the knowledgebase. I found the article pasted at the bottom of my post. Please note the spelling errors are Rockwell's. That said, do you HAVE to have the custom firmware? If the OEM is leaving you high and dry, what is the custom firmware give you?
