Place kernel as /tftpboot/boot/kernel/kernel.gz 2. Place mfsroot as /tftpboot/mfsroot.gz 3. Configure pxelinux.0 to chainload /pxeboot from TFTP. 4. pxeboot loads the kernel and mfsroot. To accomplish (4), I have the following lines in /tftpboot/boot/loader.conf: mfs_load=3D"YES" mfs_type=3D"mfs_root" mfs_name=3D"/mfsroot" ahci_load=3D"YES" vfs.root.mountfrom=3D"ufs:/dev/md0" All this however has become obsolete with the introduction of UEFI. --=20 Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/ --qMm9M+Fa2AknHoGS Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJf5gOCAAoJEA2k8lmbXsY0CRcH/itpoW3Of4rWFYgVn75OU0eP xq3lOtTVY3ue4H4wCYQlHPNHNsi/DxRuHdlsgvQyCcZ3YtGSJW/qllrtvGHOTvvG zIWC3Xs5S/HOcqBV8vS+pTzDZt/G0+dGbAfAPY15fXZRcTPLyeoe+Bdwrsd+Jtgt NhzYjD61B7S/zvEx7NRBhk6hJynyxA0ldF5sWGOj0FV5foQwo2jRtl0YXgJqyR1p Ni9UdGm2Bts2o7pcX5NCNw4YzSmQP8bKzZdtGpUtrroPmhiKVp9rkJIr59anfoKI W0gUfmGuF/ct7EMCYyapmQPY47DdoJCBAJDPppfZvfMgd3uhG8slHzkDaT8GFKU= =8isv -----END PGP SIGNATURE----- --qMm9M+Fa2AknHoGS--
