Product 

  • Asrock C236M WS Motherboard

Instructions

  • Download the C236MWS3.12E flash file HERE
  • Format a 32MB or larger USB key as FAT32
  • Copy the flash file to the root of the USB key
  • Plug the USB key into the NVR and restart the machine
  • On Boot, after the MegaRAID initializes (if applicable) and prior to the operating system loading press the Delete key “Del” to enter BIOS setup
  • When prompted enter the BIOS password “admin256” and press “Enter”. 
  • On the Main tab check the current BIOS version, listed as UEFI Version
  • If the version is L3.12E or higher a BIOS update is not required.
  • To update the BIOS, select the Advance tab, highlight Instant Flash, and Enter.  
  • Instant Flash will automatically detect all devices and only list those BIOS versions which are suitable for your motherboard, select the suitable BIOS version and press ENTER to  flash.
  • The BIOS update should progress
  • Please DO NOT power off during BIOS update.
  • After update success completes, press Enter to reboot system
  • The server will power cycle several times, press [F2] or [Del] to enter the BIOS setup utility.
  • On the Main tab verify the new version “L3.12E”
  • Verify the date and time are correct
  • Press F10 to exit BIOS and restart the machine.

Note:

In the event the BIOS password “admin256” fails after Instant Flash perform the following steps

  • Power the server off
  • Turn the individual power supplies off and remove the power cords
  • Disconnect the CMOS battery
  • Hold the power button on for a few seconds to discharge any residual power
  • Reconnect the CMOS battery
  • Reconnect the power cords and power the unit on

Traditionally systems with MegaRAID controller cards would display initialization information along with the option to enter the MegaRAID BIOS when a system is first booted.  After updating the BIOS this will no longer be the case, the MegaRAID BIOS is accessible through BIOS Setup on the Advanced tab.  If desired the older behavior can be restored by enabling CSM  “Compatibility Support Module” Parameter on the Boot tab.
