One should be aware of the limitations of the Alienware A10 cross-flash:   ATI GPU users will not able to control any chassis fans or LEDs with this process. Nvidia GPU users may install the Nvidia control panel software, and then the NVidia's "System Tools w/ESA support" addon to control the LEDs and fans. As mentioned with the A10 cross-flash above, the motherboard is identical to the Alienware Aurora ALX R1 series. A Facebook user by the name of TKMods worked with Eric Duncan to create and release a modified Alienware Aurora ALX R1 BIOS version A11. The BIOS was modified and enhanced with a number of enhancements and fixes including:   This BIOS version was packaged and released under the version XPS 730X A11b. The "b" is significant as it includes a number of bug fixes from the initial A11a release. Before upgrading, users must be aware of the following downsides:   This can resolved a number of different ways, such as pulling pin #1 from the front Panel I/O cable connector to the motherboard. "Info about the special motherboard tray and ATX, E-ATX and XL-ATX 8-slot support." Rather than having the control mechanism integrated into the H2C unit, the pump, fans and TEC are controlled separately by a Dell daughterboard, the Master Control Board (MCB). The MCB uses Enthusiast System Architecture (ESA) to monitor and control the pump, fans and TEC in addition to controlling the XPS LED lights, other fans, and sensors. The H2C cooling and LED lighting system cannot be reused in another computer case without the MCB or custom-made control circuits to take its place. Because the MCB is based on Nvidia's ESA technology, it is open to be controlled via non-Dell software. Currently the only software available is Nvidia's System Tools which is available as a plug-in for Nvidia's Control Panel that comes with every Nvidia driver install. The control software from nVidia will not install if no other nVidia products (such as a graphics card, chipset or drive controller) are present in the PC. The software can be installed if the motherboard uses an nVidia chipset, or if an nVidia graphics card is used as the primary display adapter. In a PC with an ATI/AMD graphics card as the primary display adapter, and no nVidia chipset on the motherboard, an option is to install a secondary graphics card with a nVidia GPU.
