-						The most glaring issue on modern Intel hardware (beyond year ~2008) is
-						the <i>Management Engine</i>. This is a separate processor that exists in all Intel chipsets
-						past the year ~2006; some systems between those years can have the Management Engine firmware
-						removed (with the ME processor permanently deactivated), but not replaced (due to cryptographic signature checking on the firmware)
-						- see <a href="../docs/hcl/gm45_remove_me.html">../docs/hcl/gm45_remove_me.html</a>.
-						The management engine provides remote access capabilities, independently from the running operating system. It has full access to
-						your RAM, and it has full networking support. It also handles the TPM module, AMT (Active Management Technology), Boot Guard and
-						various <a href="https://defectivebydesign.org/what_is_drm_digital_restrictions_management">DRM</a> mechanisms.
+						The ME is a separate processor that exists in all Intel chipsets past the year ~2006. It provides remote access capabilities,
+						independently from the running operating system, with full access to RAM, and full networking support. With a functioning ME, your system
+						is left wide open for attack. It can also phone home to Intel. It also handles the
+						TPM, AMT (Active Management Technology), Boot Guard and various <a href="https://defectivebydesign.org/what_is_drm_digital_restrictions_management">DRM</a> mechanisms.

-						All modern Intel systems built after around the year 2008 (after ICH9) require this blob, and
+						The ME is <i>cryptographically signed</i>, which means that you cannot run a modified version of it. You also can't boot without it.
+						On some older chipsets (ICH8 and ICH9), it's possible to remove the ME <i>firmware</i> and still have a functioning system, where
+						the ME itself is permanently deactivated. For instance, libreboot supports several ICH9 based
+						laptops; see <a href="../docs/hcl/gm45_remove_me.html">../docs/hcl/gm45_remove_me.html</a>.

 						key, necessary for signing the firmware). The Management Engine is covered on a lot of websites
