Surely the host BIOS will know to place the RMRRs outside its BIOS image. > Host BIOSes are generally large compared to the guest BIOS, but with the > amount of decompression and relocation etc they do I don't know how much > of them generally remains in the <1MB region. Recall the example: (host) RMRR naming E0000-EFFFF, which overlaps with the init-time guest BIOS image, but doesn't overlap with its resident part (as long as that doesn't exceed 64k in size).
