So you're saying that the EFI in the kernel now still won't support more than 128 or so chunks of memory in the boottime memory map, because it still goes via the legacy E820h memory map code? I'll have to study the code more and give it a try. Are you optimistic that some variation of H. Peter Anvin's "struct setup_data" mechanism will make it into 2.6.25 or thereabouts? -- I won't rest till it's the best ... Programmer, Linux Scalability Paul Jackson 1.940.382.4214
