  9. IA-64 identity-mapped regions use a large page size called "granules".
  10. Select "16MB" for a small granule size.
  11. Select "64MB" for a large granule size. This is the current default.

  20. Selecting this option prints more information for Illegal Dependency
  21. Faults, that is, for Read-after-Write (RAW), Write-after-Write (WAW),
  22. or Write-after-Read (WAR) violations. This option is ignored if you

  29. The Virtual Hash Page Table (VHPT) enhances virtual address
  30. translation performance. Normally you want the VHPT active but you
  31. can select this option to disable the VHPT for debugging. If you're
  32. unsure, answer N.

  37. Selecting this option turns on bug checking for the IA-64
  38. compare-and-exchange instructions. This is slow! Itaniums
  39. from step B3 or later don't have this problem. If you're unsure,
  40. select N.
