If you can figure out how to construct an EFI GPT partition structure on it, 'GEOM' will detect and use it via sys/geom/geom_gpt.c. Note that /sbin/gpt needs lots of work. Right now the only way to do things is to use fdisk to initialize it and "convert" it to gpt. This turned out to be rather painful, but I eventually convinced it to do what I needed. It shouldn't be all that hard to finish it off. The biggest problem I had was that GEOM didn't have any way to do this live. I had to create the partitions on a non-geom kernel, then reboot to see if it worked etc. Cheers, -Peter -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com "All of this is for nothing if we don't go to the stars" - JMS/B5 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
