• Memory cycles below 16 MBytes (1000000h)
• I/O cycles below 64 Kbytes (10000h)
• The Internal I/OxAPIC at FEC0_0000 to FECF_FFFF
• Memory cycles in the LPC BIOS range below 4 GByte
are still decoded when this bit is set, but the aliases at
the top of 1 MByte (the E and F segment) are no
longer decoded.
