ROM Version 109 (this release) fixes a rare occurence of corruption or hang for a few specific instances.
Added built-in Firmware Fan control - Fan control has been implemented within the card's firmware to maintain full fan control with or without the presence of the ATI ROM Xtender file. This update is recommended for all RADEON X800 XT MAC EDITION cards. Previous reports documented the loss of fan control after accidentally losing the ATI ROM Xtender in the System's Extension folder. With this update, fan control is enabled early in the boot process and maintained with or without this extension file present. To re-install the extension file, simply run the original RADEON X800 MAC EDITION installation CD, this update or a newer ATI Web released driver update.
