It's certainly simpler than the current state of afairs and unless the kernel NDIS grows the ability to directly read .sys & .inf files from your disk (which would be very cool :) it's about a simple as it's going to get.. > - What should the script be called? wintobsd.sh sounds kind of lame. encappe win2elf pe2elf -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQBCZcO75ZPcIHs/zowRAmtUAKCqJGRLE2dZzqv4PA1xnRzX9iOZGwCeKfHP 7UXPSSZDop5mc/rd1faJmm4= =xt0l -----END PGP SIGNATURE-----
