If I understand you, you are trying to install enough of FreeBSD on a disk that you will then move to another machine to finish the install??? First of all, why don't you just do the complete install on the disk rather than just a part of it. Second, did you write the MBR to the disk? I would suggest this: dd if=/dev/zero of=/dev/da1 bs=512 count=32 fdisk -BI da1 That first dd just makes sure no previous junk on the disk gets in the way. The fdisk command writes two main things: The primary slice table and the MBR. But, it does not put the boot sector there. That is done with bsdlabel. bsdlabel -w -B da1s1 will do it Then, you have to divide that slice you made in the fdisk command into at least one partition - probably several. FreeBSD doesn't boot to the slice, but rather needs a real partition that has been made in to a file system and had needed files written on it. For that you again use bsdlabel. The easiest is to use it in edit mode: bsdlabel -e da0s1 That puts you in an edit session to edit the partition table for the slice. Edit it as you prefer. I posted a long response yesterday that gives a good example. Then, you should install all of what goes in root and preferably also what goes in /usr before trying to boot. You can do all this through sysinstall and if you really must only partially install, then just get really selective on what you tell it to install rather than just take the general/normal installation. But, as I said above, just do the whole install at this time. The only thing you might come out funny on are the device names it puts in /etc/fstab. In might name them da1 or ad1 instead of the da0 or ad0 you need when you move the disk over to the other machine. So, mount up the newroot (on the new disk) and check out the /newroot/etc/fstab file and edit if necessary before moving the disk over. ////jerry > > Thanks, > Steve > > -- > Steve Franks, KE7BTE > Staff Engineer > La Palma Devices, LLC > http://www.lapalmadevices.com > (520) 312-0089 > _______________________________________________ > firstname.lastname@example.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
