AUTO BIOS Implementation Test Suite (BITS)

Modified to automatically load microcode before OS boot: "AUTO-BITS"

The reason for the existance of this fork is that manufacturers often do not support older motherboards/BIOS with updates. This leads to vulnerabilities like Meltdown/Spectre not getting patched while the microcode is available. This fork can be used to automatically load microcode before loading OS (using GRUB). By default it will try to boot from the first drive. I have successfullly tested it by booting from USB stick with Windows 10 (and Linux). It should work with other Windows versions and OS'es too.

  • Now also available as ready-made images with the 'AUTO' changes included

  • Latest version of bootable ISO and USB image ready to be written to disk:

Screenshots

boot

"Boot an OS from disk" loads after 2 seconds, unless a menu entry is selected

menu

Multiple OS entries can be selected, the last 2 were added automatically

os

"Configure Menu" (microcode can also be autoloaded, see Auto Boot below)

microcode

Notes

  • Microsoft apparently includes microcode updates now in Windows 10 for certain CPU's, this is ofcourse the preferred way to load microcode.
  • VMware CPU Microcode Update Driver will not be able to accomplish the same as BITS since it loads microcode much later in the boot process; as driver within the OS itself.
  • As you probably know, but just to be sure: Linux already does this by itself (e.g. Debian and CentOS)

Instructions

  • Note that this repo does not include "/efi" dir (get it here or from Intel)
  • Write to USB stick according to original instructions (INSTALL.txt)
  • Copy this repo to /boot
  • You also need microcode from Intel which goes to /boot/mcu/microcode.dat (Google "latest Linux Processor Microcode Data File")
  • Optionally; if you put the data file in /boot/mcu.first that file will be loaded first (see microcode.txt)

Original version and documentation

The last 2 entries in the menu use:

Changed from original

  • automatically load microcode (auto.cfg)
  • auto detect OS using various methods and boot it (boot_ext.cfg)

Auto Boot

First microcode is loaded and then OS is booted:

If your OS is not on the first drive try one of the other menu entries. If you have found an entry that works you can permanently change default in boot_ext.cfg (top).

The menu entries you can choose from are:

  • Generic (BIOS/MBR):

    • "Boot first drive MBR"
    • "Boot second drive MBR"
    • "Boot first drive MBR, Extended partition"

  • Linux (EFI, BIOS/MBR):

    • "Linux (autodetect: /etc/passwd)"
    • "Linux (seperate "/boot" on Extended partition)"
    • "Load another configfile (autodetect: grub.cfg)"
    • "Chainload MBR from file "linux.bin"

  • Windows (EFI, BIOS/MBR):

    • "Microsoft Windows Vista/7/8/10 bootmgr (MBR)"
    • "Microsoft Windows NT/2000/XP ntldr (MBR)"
    • "Microsoft Windows UEFI"
    • "Windows (aioboot)"

  • Other: BSD/ISOLINUX/DOS (BIOS/MBR):

    • Last menuentry (osdetect)

microcode
Notes
  • Microsoft apparently includes microcode updates now in Windows 10 for certain CPU's, this is ofcourse the preferred way to load microcode.
  • VMware CPU Microcode Update Driver will not be able to accomplish the same as BITS since it loads microcode much later in the boot process; as driver within the OS itself.
  • As you probably know, but just to be sure: Linux already does this by itself (e.g. Debian and CentOS)
Instructions
  • Note that this repo does not include "/efi" dir (get it here or from Intel)
  • Write to USB stick according to original instructions (INSTALL.txt)
  • Copy this repo to /boot
  • You also need microcode from Intel which goes to /boot/mcu/microcode.dat (Google "latest Linux Processor Microcode Data File")
  • Optionally; if you put the data file in /boot/mcu.first that file will be loaded first (see microcode.txt)

Original version and documentation
The last 2 entries in the menu use:
Changed from original
  • automatically load microcode (auto.cfg)
  • auto detect OS using various methods and boot it (boot_ext.cfg)
Auto Boot
First microcode is loaded and then OS is booted:
If your OS is not on the first drive try one of the other menu entries. If you have found an entry that works you can permanently change default in boot_ext.cfg (top).
The menu entries you can choose from are:
  • Generic (BIOS/MBR):
    • "Boot first drive MBR"
    • "Boot second drive MBR"
    • "Boot first drive MBR, Extended partition"
  • Linux (EFI, BIOS/MBR):
    • "Linux (autodetect: /etc/passwd)"
    • "Linux (seperate "/boot" on Extended partition)"
    • "Load another configfile (autodetect: grub.cfg)"
    • "Chainload MBR from file "linux.bin"
  • Windows (EFI, BIOS/MBR):
    • "Microsoft Windows Vista/7/8/10 bootmgr (MBR)"
    • "Microsoft Windows NT/2000/XP ntldr (MBR)"
    • "Microsoft Windows UEFI"
    • "Windows (aioboot)"
  • Other: BSD/ISOLINUX/DOS (BIOS/MBR):
    • Last menuentry (osdetect)

AUTO BIOS Implementation Test Suite (BITS)
Modified to automatically load microcode before OS boot: "AUTO-BITS"
The reason for the existance of this fork is that manufacturers often do not support older motherboards/BIOS with updates.
This leads to vulnerabilities like Meltdown/Spectre not getting patched while the microcode is available.
This fork can be used to automatically load microcode before loading OS (using GRUB). By default it will try to boot from the first drive.
I have successfullly tested it by booting from USB stick with Windows 10 (and Linux). It should work with other Windows versions and OS'es too.

  • Now also available as ready-made images with the 'AUTO' changes included
  • Latest version of bootable ISO and USB image ready to be written to disk:
