How do I get it to boot again? =20 Make sure you've got boot0 on the primary master (assuming IDE) or da0 (SCSI) and on no other drives. Booting from one boot manager on the BIOS boot disk to boot0 on another drive hasn't worked well in my experience. =20 Also, make sure FreeBSD's idea of your drive geometry matches what the BIOS thinks. Posting disklabel and 'fdisk -s' output might help. (The fixit CD is your friend here.) --=20 andrew y ng http://andrewng.com fingerprint : 46a1 29ff 893a 0381 dc81 1e1e bed8 e882 9bfc 594c --=-NOtYYz0nWUf1w38bE0w2 Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (FreeBSD) iD8DBQA93Xiuvtjogpv8WUwRAsofAKDsMA6rGCf4AsG3dH1fVuT/q01VKACg6W4u X/4Utk6V3Z7oBUMI+FW9UYg= =G+PB -----END PGP SIGNATURE----- --=-NOtYYz0nWUf1w38bE0w2-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
