Note:
Please update all binary code (BIOS, UEFI, BOOT, FIRM
and MBR0) before you reboot system. Otherwise, a mixed
firmware package may result the controller hang.
Appendix A
Upgrading Flash ROM Update Process
A-1 Overview
Since the SAS RAID controller features flash ROM firmware, it is
not necessary to change the hardware flash chip in order to up -
grade the RAID firmware. The user can simply re-program the old
firmware through the in-band PCIe bus, out-of-band Ethernet port
McRAID storage manager or nflash DOS utility. New releases of the
firmware are available in the form of a DOS file on the shipped CD
or Areca website. The files available at the FTP site for each model
contain the following files in each version:
ARC1883UEFI.BIN: → An EFI shell and a home brewed small appli-
cation
ARC1883BIOS.BIN : → PCIe 3.0 BIOS for system board using
ARC1883BOOT.BIN : → RAID controller hardware initialization
ARC1883FIRM.BIN : → RAID kernel program
ARC1883MBR0.BIN: → Master Boot Record for supporting Dual
Flash Image in the 12Gb/s SAS RAID controller
README.TXT contains the history information of the software code
change in the main directory. Read this file first to make sure you
are upgrading to the proper binary file. Select the right file for the
upgrade. Normally, user upgrades the ARC1883BIOS.BIN for sys -
tem M/B compatibility and ARC1883FIRM.BIN for RAID function.
All these files in the firmware package are a part of the firmware.
You should update all files in the package, no special update order
needed. New firmware works after a system restart not instantant
available, so you can update all files before restart the system. The
controller firmware is independent of the array, update firmware
does not touch anything you stored in the array.
