Bret, none of that much drama will be necessary :) Manolis nailed it, but I'll add a little reinforcement if it helps reassure you that what you want to do is a) entirely possible and b) not terribly difficult. > And, with being required to do all of that, I do not know what would > happen, regarding issues such as the interrupt conflict that I > encountered when trying to initially install Debian 3.1 on the computer, > the interrupt conflict being between the WiFi card and the ethernet > card, which reuired Ubuntu to resolve the conflict, then (at the time, > as I was then a strictly Debian user) uninstalling Ubuntu to reinstall > Debian 3.1, with the solution to the interrupt conflict, having used > Mandriva Linux to do the partitioning, so as to retain the initial > installation of MS Win XP, which I would probably lose, and have to > install from scratch, as part of installing BSD on the system. I can't comment on your wifi or interrupt issues, but there's no reason you need to lose any of your existing systems to install FreeBSD here. First, make SURE you have good backups, whatever else you do. Sooner or later the HD is going to fail anyway, so be prepared and be comfortable. More or less as Manolis later said, using gparted since you have it: a) delete the 20GB logical partition /dev/sda8 for the space you need. b) move the free space in the extended partition to the end, after the present sda9 and sda10. these may then become sda8 and sda9, and you may later need to edit references to these to account for renumbering. c) shrink the extended partition sda2 to the end of (now) sda9, which will provide 20GB of unallocated free space on the disk. d) create a new slice (primary partition in DOS terms) using all of the 20GB free space. gparted will call it /dev/sda3, and it'll be the third partition in the MBR. FreeBSD will see this as slice /dev/ad0s3, and there you can install FreeBSD, probably in several FreeBSD partitions. > So, getting the system set up, initially, to get Debian 3.1 running (it > has been superseded on the system, first by Debian 4, and, now, by > Debian 5), took a fair bit of time and effort, and problem solving, > using various operating systems, to get the one extra operating system > installed.

Just a bit more learning, shifting a bit further from 'DOS-think' > If FreeBSD would be able to be installed in a logical partition, within > an extended partition, as can be done with Linux, it would probably be > able to be done by me - in the meantime, it is simply too difficult. It's only too difficult until you know how to do it. Manolis and I have both shown you a fairly straightforward way of doing it, and others have provided good background info on how FreeBSD uses diskspace. Go for it! As a bonus, you should be able to access all of the other filesystems on your disk from FreeBSD, at least read-only. FAT32 (mount_msdosfs), NTFS (I don't, but many people here have done), ext3 - not sure about write capability, but certainly ext2. Way back on FreeBSD 3.3 I salvaged many OS/2 HPFS filesystems from various extended partitions, readonly, and last time I looked (FreeBSD 7.0) the HPFS code was still in the tree. You'll find that FreeBSD knows the (covering) extended partition as /dev/ad0s5 and the logical partitions within as /dev/ad0s6, s7 etc. FAT32 is reliable read-write, and most useful for shipping files between different OS, especially if you enclose them in a tar(1) or zip(1) file if you need to maintain file ownerships and permissions. cheers, Ian _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
