Wilkerson" Message-Id: <199601272010.PAA08983@hopf2.math.purdue.edu> To: DHIMAN@d0sb15.FNAL.Gov, hackers@freebsd.org Subject: Re: a question about boot-manager Cc: freebsd@hopf.math.purdue.edu Sender: owner-hackers@freebsd.org Precedence: bulk I currently am running a system that has DOS, FreeBSD, and Linux loaded. I use the FreeBSD bootmanager, BootEasy. Because it uses the bios, my understanding is that the partitions it boots have to be visible to the bios. In my case, DOS is on first disk, FreeBSD on second, and Linux on the third. I boot linux by first booting DOS and then using Lodlin15 package to boot Linux. The dos directory contains a copy of the linux kernel which is read in and started. Then it knows about extra disks, and partitions beyond the usual limits. To do this on one large disk with only BootEasy, I think your DOS will need to be entirely low ( below 1023 cylinders ). Linux could be started from a very small partition containing essentially only a kernel, and I suspect the same for FreeBSD. Good luck, Clarence Wilkerson
