PAM3_LOENABLE. 0D0000h–0D3FFFh Attribute (LOENABLE)
This field controls the steering of read and write cycles that address the BIOS
area from 0D0000h to 0D3FFFh.
00 = DRAM Disabled: All accesses are directed to ESI.
01 = Read Only: All reads are sent to DRAM. All writes are forwarded to ESI.
10 = Write Only: All writes are send to DRAM. Reads are serviced by ESI.
11 = Normal DRAM Operation: All reads and writes are serviced by DRAM.
