Flash update instructions for the AcceleRAID 250 SOFTWARE KIT 4.01 The attached flash files are for the Mylex AcceleRAID 250 controller ONLY. Flashing these files to a controller other than the model specified may render the controller inoperable. This release is contained within the Software Kit 4.01 CD. Use EzAssist -> Advanced Options to flash the controller with each of the four update files. (Write down the filenames so they can be entered when prompted by EzAssist.) NOTE: If your controller is currently using the DACCF version of the configuration utility, you must run the DOS based RAID EzAssist utility to update the files. Before upgrading the firmware from a version less than 4.07, make sure that the Background Initialization has completed. Background Initialization occurs immediately after a New Configuration is saved and usually takes a few hours. It is characterized by significant drive activity. Make sure this activity has stopped before upgrading the firmware.
