Yes, Red Hat will install in (and boot from) a logical drive in an extended partition. This isn't that unusual; OS/2 has done it for years! In fact, it's a good way to go, since with a boot manager that understands this scheme you can have up to 23 OSes co-resident on one machine. The trick is (as I mentioned above) the boot manager. The boot manager is installed in one of the four primary partitions (usually the first), and that partition is permanently marked as "Startable." (If an OS install mucks with that, there's usually a way to give it control again via a floppy disk.) The boot manager, in turn, hands off control to the chosen OS, which resides in one of the other partitions (primary or extended; it doesn't matter). V Communications' System Commander and IBM's Boot Manager both work this way. FreeBSD doesn't come with a boot manager that can do this, but as I understand it you can use a third-party boot manager and partition management program (e.g. System Commander plus Partition Commander) to make it boot out of a primary partition that's not marked as startable. You may also be able to make it boot out of a logical drive, so long as it doesn't freak out when it discovers that it's located there; I haven't tried it. --Brett Glass To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
