Building a VM86 emulator that can usefully execute a binary driver - especially a performance-critical one like a video driver - is a totally different undertaking. --=20 Peter Jeremy --k4f25fnPtRuIRUb3 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (FreeBSD) iD8DBQFEpOiR/opHv/APuIcRAvgsAJ414t5jQBimvZ1W3j2JxHbKURb10gCgn6vt O6+Pkf39vmKxBVQQpIEEem0= =Z7rB -----END PGP SIGNATURE----- --k4f25fnPtRuIRUb3--
