NOTE: THIS IS A SPECIAL VERSION OF THE XMC-1 FIRMWARE FOR USE WHEN SELF-INSTALLING THE NEW HDMI 2.0b VIDEO UPGRADE BOARD. DO NOT INSTALL THIS FIRMWARE ON AN XMC-1 THAT HAS THE ORIGINAL VIDEO CARD UNLESS YOU ARE IN THE PROCESS OF INSTALLING THE UPGRADE BOARD. THIS FIRMWARE INCLUDES A SPECIAL INSTALLER WHICH WILL INSTALL V5.2 WHILE THE OLD (INCOMPATIBLE) VIDEO CARD IS STILL INSTALLED. THIS IS A NECESSARY STEP WHEN SELF-INSTALLING THE HDMI UPGRADE CARD. IF YOU INSTALL IT ON AN ORIGINAL XMC-1, WITHOUT INSTALLING THE NEW HDMI CARD, IT WILL RENDER YOUR XMC-1 PARTIALLY NON-FUNCTIONAL. (If this happens, re-install firmware v4.1, either by downloading firmware v4.1, or by downloading the new FULL INSTALLER, which will install the correct version for your unit.)
NOTE: Because this is a special version of the firmware, it may not be undated as often as the full version. Therefore, in order to have the latest firmware on your XMC-1, you may want to install the FULL VERSION after performing the hardware update using this version.
