My plan was to install on wd1:a working copy of freebsd, a test copy of freebsd, and a working copy of linux. I had no plan to use a disk manager and so wanted to keep roots below the 1024 cylinder boundary. PM-BootManager seem to work well ( after setting the disk geometry ) I suppose that lilo or booteasy would work equally well; but I don't want to change my wd0 MBR till I have more confidence in my knowledge of the systems involved. I thought to partition wd1 as: < slice - the remaining physical disk> My question is: is this reasonable, or am I shooting myself in the foot? > Greg > -- > When replying to this message, please copy the original recipients. > For more information, see http://www.lemis.com/questions.html > See complete headers for address, home page and phone numbers > finger grog@lemis.com for PGP public key To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
