PAM6_HIENABLE. 0EC000h-0EFFFFh Attribute (HIENABLE).
This field controls the steering of read and write cycles that address the BIOS
This field controls the steering of read and write cycles that address the BIOS
area from 0EC000h to 0EFFFFh.
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.
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.
