Once that is done, the rest of this document should be general enough (or at least that was the intent). About defining those criteria, I'd appreciate whatever input you x86 experts will be able to share. :-) Regards, Dario --=20 <> (Raistlin Majere) ----------------------------------------------------------------- Dario Faggioli, Ph.D, http://about.me/dario.faggioli Senior Software Engineer, Citrix Systems R&D Ltd., Cambridge (UK) --=-b2ZLX44mBCg7un8IsAIn Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJYSTS/AAoJEBZCeImluHPuhocP+gP8vbuCkiPJAO7CsMzdGctv nyF66GhUDn8K8waqg3yQNw2CpDcSn2Smu+NiB4WKMiFriCxepAU1wd71lwwm+gtU /MwWgQnHGEXmSP4qOw9fS1AN//XUum0MzG21Pk7k+PHeixskDZIxGlgx/Yn2o/mk M9EgFNZyzFYeBUpCNirnef1rPECWxh787pZd8ISG0b12Q7/dtve4hWPJWOsDCPoF lRBkI6/lLh/zwwEChlZOZu3ugYGoKbcYA/QCQ+wqnqETdOk+jOhjaek1oVb4rOle 23N8s/qabYpU8y8L6F1SUiDpsexxuP0NQ6TCMej2nDSwa/uDd6VXdFTxZqDsIAAh 73WRUwE8TrTxj8XTL002b9pil7AS+Nb112MA+XE8mFipnXVFzWN9AJ6bWlY2/S66 5W16yrO62t3M5/1p/f3lXU43+5xUnj1Qcd5evrpfIPcEtrzrPsnCsuYjCDx1kbXp sjdDmo4JNecgqzb+lK6eSwXkwQ0xkwiwsTsn7b8RRqXPfJCQFyB80uI370Uew3lh +7H3L8+PSQdUN85Mcdrb55zHNAUggyXgK81s9NatDwBryp9cSpJtUom4deH6Xfdd NrHtZ+JUFfalXU2kjo0UIY/oAPaj2Pm+2ZgvBNKSY7o9KDcr5elv1wgDgZU/rX5u ZnfIJhNTMOTVJN4wcErj =dqFN -----END PGP SIGNATURE----- --=-b2ZLX44mBCg7un8IsAIn-- --===============5466730625284196281== Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: base64 Content-Disposition: inline X19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX18KWGVuLWRldmVs IG1haWxpbmcgbGlzdApYZW4tZGV2ZWxAbGlzdHMueGVuLm9yZwpodHRwczovL2xpc3RzLnhlbi5v cmcveGVuLWRldmVsCg== --===============5466730625284196281==--
