<p>A casual reader might easily overlook this option, or misinterpret it to mean that the feature is much less important than it is. In fact, this particular motherboard offers very poor control over its EFI vs. BIOS booting features. (See <a href="http://www.rodsbooks.com/gb-hybrid-efi/">my Web page on this EFI implementation</a> for details.)</p>\r

-<p>Some manuals omit even mention of EFI, and instead refer to "legacy boot" or some similar term, referring to BIOS-style booting. Such references may imply that the firmware supports EFI booting if the "legacy boot" mode is disabled or restricted in some way.</p>\r
+<p>Some manuals omit even mention of EFI, and instead refer to "legacy boot" or some similar term, referring to BIOS-style booting. The firmware for my ASUS P8H77-I motherboard uses the technical term <i>CSM,</i> which of course will be baffling to the uninitiated. (I referred to it earlier. It's the <i>Compatibility Support Module</i>—in other words, the BIOS support code.) Such references may imply that the firmware supports EFI booting if the "legacy boot" mode is disabled or restricted in some way.</p>\r

<p>Understated EFI features often indicate a slapdash approach to EFI. Such systems sometimes implement EFI as a layer atop a conventional BIOS. More modern EFIs, though, completely replace the BIOS. Some manufacturers, such as ASUS and its sibling ASRock, are now actively promoting their more advanced EFI implementations. Such products often come with flashy new GUIs in their firmware.</p>\r
