Intel's 64 and IA-32 Developers Manual (#325462-043US) denotes on page 2328
Quote:
LM: IA-32e mode support.
If CPUID.80000001H:EDX.LM [bit 29] = 1, IA32_EFER.LME may be set to 1,
enabling IA-32e paging. (Processors that do not support CPUID function
80000001H do not allow IA32_EFER.LME to be set to 1.)
and on previous page
Quote:
PAE: physical-address extension.
If CPUID.01H:EDX.PAE [bit 6] = 1, CR4.PAE may be set to 1, enabling PAE
paging (this setting is also required for IA-32e paging).
In my mind, LM should imply PAE but the highlighted text leads me to think that might not be the case.
Could this be possible and if so, on which devices?
