 +Slackware setup supports UEFI installs.  To get Slackware to boot on UEFI machines, bypass the LILO installation and select ELILO installation when prompted during the install.
  
-Some modern computers have started to offer motherboards that use Unified Extensible Firmware Interface (UEFI) as a replacement for the traditional BIOS. Slackware is perfectly capable or running on such machines, albeit with the provisos that the official install media cannot be booted via UEFI directly and no UEFI bootloader is provided as part of the official selection of packages.

 +If you do wish to install Slackware on a UEFI based machine it is **//strongly//** recommended that you use Slackware64 14.1 or above, thus allowing you to simply boot the official install media.

 +If you have a requirement for Slackware 14.0you will need to follow one of our approaches:
  
   * Enabling legacy BIOS support   * Enabling legacy BIOS support

 ===== Legacy BIOS support ===== ===== Legacy BIOS support =====
  
 The majority of new UEFI-based machines have options to simulate a traditional BIOS. This is often referred to Legacy BIOS support. If your machine supports this it should be your first choice, as once enabled you can continue to install Slackware as you have always done, using the official install media and setup instructions. How you enable this mode varies from manufacturer to manufacturer. Refer to your vendor's documentation on how to enable this mode. The majority of new UEFI-based machines have options to simulate a traditional BIOS. This is often referred to Legacy BIOS support.

-===== Creating your own install media =====+===== Creating your own install media for older Slackware releases =====
  
 The easiest way to make your own Slackware UEFI-capable install media is to create a USB boot disk. To do so you may need to use a second machine. Alternatively you can use the target machine directly if it has another OS installed that provides a GPT (GUID Partition Table) capable partitioning tool or you have UEFI-capable Live media (CD, DVD, USB, etc.) provided by another Linux distro, which includes such a utility. Suitable partitioning tools include GPT fdisk (a.k.a gdisk) and GNU parted, both of which are provided by recent versions of Slackware. The easiest way to make your own Slackware UEFI-capable install media is to create a USB boot disk.
