Updating the BIOS: • Download both files from supplied NAI FTP (or One Drive) site: • IBC10i_ME1.5M_SPI16MB.bin • H2OFFT-Sx64.efi • Copy both files onto a USB stick. • Attach USB to the 75Int2 (NOTE: you will need a USB hub to be able to connect a keyboard, mouse and the USB stick). Connect all three to a USB hub and connect the hub to the 75Int2 USB connector (connector will either be from a supplied rear transition card if the 75Int2 is not part of a SIU system or a cable off the back of the SIU system. NOTE: Below, if you find you are having trouble being able to “break” into the BIOS (i.e. pressing <ESC> does not get you to the BIOS menu selection) you may need to try another USB ub. Some USB hubs do not power up the keyboard in time to break into the BIOS. We have found older USB hubs supporting the slower speeds seem to work best. • Provide power to the 75Int2 board (power on the system) • Press <ESC> key on keyboard during bootup. • Arrow Down and press <Enter> on Setup Utility (NOTE: if you see buttons on the screen as opposed to menu items, arrow over to the button that says SCU and press <Enter>) • Left click on Boot tab (at top): • Left click Boot Type • Select Dual Boot Type • Press F10 and Enter to save and exit. • Press <ESC> key on keyboard during reboot. • Arrow Down and press <Enter> on Boot Manager (If you see buttons instead of menu items, arrow over to the button that says Boot Manager and press <Enter>) • Arrow Down and press <Enter> on Internal EFI Shell • The EFI shell should start and you should see a “Shell>” prompt • Type: map -r <Enter> • You should see an entry starting with “fs#” with the text “:Removable HardDisk” after it. Take note of the numeric value at the location of the # sign in “fs#”. Typically it is “fs0” if it is different use the number you see in the next command. • Type: fs0: <Enter> (you are now at the root of the USB stick. If you placed the 2 files at the root of the filesystem on the USB stick continue on to the next step. If you placed them in a subfolder, please cd into that subfolder now. You can also use the command “ls” followed by <Enter> to see what files are in the current directory. • Type: H2OFFT-Sx64.efi IBC10i_ME1.5M_SPI16MB.bin -bios -all -ssb <Enter> • Once you press <Enter> the BIOS flash utility application will start. !!!DO NOT POWER OFF!!! When the utility is done flashing the BIOS, the 75Int2 will get powered off. (When the screen goes black, you can now recycle power on the 75Int2).

On 1st Boot: • Press <ESC> on keyboard during bootup. • Enter Setup Utility • Under Main tab: • Go to “System Time” and update the time to the current time. • Go to “System Date” and update the date to today’s date. • Under Advanced tab: • Left click Thermal Configuration • Left click Platform Thermal Configuration • Under Shut Down Temperature select maximum temp (120) • Under Throttle On Temperature select maximum temp (90) • Press <ESC> key • Press <ESC> key (again) • Still under Advanced tab…​Left click PCI Express Configuration • Under cPCI IRQ Routing set to Slot 2 • Press <ESC> • Left click Boot tab (at top): • Left click Boot Type • Select Legacy Boot Type and press Enter • Press F10 and Enter to save and exit. • Allow the system to boot to CentOS 7.4 •

Console Redirection Configuration Instructions: • Boot into CentOS 7.4 on the 75Int2 • At login prompt, log in as root: (From factory: u: root p:123456) • Edit the grub configuration file (highlighted items are new additions): • #vi /etc/sysconfig/grub File should look like the following: GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR=”$(sed ‘s, release .*$,,g' /etc/system-release)” GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL=”serial console” GRUB_SERIAL_COMMAND=”serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1” GRUB_CMDLINE_LINUX=”crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet plymouth.enable=0 intel_pstate=disable i915.enable_rc6=0” GRUB_CMDLINE_LINUX_DEFAULT=”console=ttyS0,115200n8 console=tty0” GRUB_DISABLE_RECOVERY=”true” • Save the grub configuration: <ESC>:wq • Now make grub changes permanent for next boot: • # grub2-mkconfig -o /boot/grub2/grub.cfg • Make sure external serial cable is hooked up and settings in console application (like TeraTerm on Windows or minicom on Linux) are set for: • 115200 (Baud/speed) • 8 bit • No Parity • 1 Stop Bit • No Flow Control • Reboot the system • # shutdown -r now System should now boot and you should end up with a login prompt on the Serial console as well as VGA (if VGA is still hooked up).
