In the case -where you wish to boot off an alternate drive, it should also be noted -that you still need to install a boot manager on the FIRST drive! -Even if you do not intend to create a FreeBSD partition on that drive -(e.g. it's being wholly used by something else), the boot manager -still needs to reside on the first disk in order to function as a -"redirector" for the boot process. - -To do this, simply select your 1st drive in the drive selection menu -and when the partition editor comes up, don't make any changes - just -(Q)uit. At the boot manager menu which follows, select the first -option (install a boot manager) and then proceed to setup the other -drive(s) for FreeBSD as normal. - -It should also be noted that "operating systems" such as Windows 95 -will completely overwrite your boot manager without so much as a -polite "may I please destroy your boot manager?" prompt if you make -the mistake of installing them second. If this happens to you after -FreeBSD is already installed, all is not lost! Simply revisit your -FreeBSD distribution directory and look for a tools/ subdirectory, in -which you'll find "bootinst.exe" and "boot.bin". To reinstall, simply -say "bootinst boot.bin" while in the tools/ subdirectory. - - -If you see the boot manager displaying ``F?'' when you try to come up -for the first time and it refuses to change, no matter how often you -whap on the function key assigned to FreeBSD, then you have a geometry -mismatch problem and you should read the next section for important -information on how to prevent that exact problem from happening! - - -Geometry Translation / Sharing the disk(s) with another OS: ----------------------------------------------------------- - -If you are going to actually install some portion of FreeBSD on a -drive then PLEASE BE VERY CERTAIN that the Geometry reported in the -Partition Editor is the correct one for your drive and controller -combination! - -IDE drives often have a certain geometry set during the PC BIOS setup, -or (in the case of larger IDE drives) have their geometry "translated" -by either the IDE controller or a special boot-sector translation -utility such as that by OnTrack Systems. In these cases, knowing the -correct geometry gets even more complicated as it's not something you -can easily tell by looking at the drive or the PC BIOS setup. The -best way of verifying that your geometry is being correctly calculated -in such situations is to boot DOS (from the hard disk, not a floppy!) -and run the ``pfdisk'' utility provided in the tools/ subdirectory of -the FreeBSD CDROM or FTP site. It will report the geometry that DOS -sees, which is generally the correct one. - -If you have no DOS partition sharing the disk at all, then you may -find that you have better luck with Geometry detection if you create a -very small DOS partition first, before installing FreeBSD. Once -FreeBSD is installed you can always delete it again if you need the -space. - -It's actually not a bad idea (believe it or not) to have a small -bootable DOS partition on your FreeBSD machine anyway: Should the -machine become unstable or exhibit strange behavior at some point in -the future (which is not uncommon behavior for PC hardware!) you can -then at least use DOS for installing and running one of the -commercially available system diagnostic utilities. - -IMPORTANT NOTE: - -Any root partition you try to boot from must also reside below the -1024th cylinder. If you're using a translated geometry then this is -probably not a problem, but if you are using a native disk geometry -which exceeds 1024 cylinders then you could have a failure to boot if -you end up installing a root partition (or even just the kernel file -in a root partition) out past cylinder 1024. If you are trying to -share your first disk with FreeBSD and another OS which was installed -previously, you are particularly susceptible to this problem and should -check your disk addresses very carefully. - -If you find that you have insufficient space below cylinder 1024 to -make a root partition for FreeBSD (and again, this ONLY applies to the -root partition - once FreeBSD's kernel is loaded, it doesn't care -about the geometry issues) then you will probably need to install on a -completely different disk (see the boot manager section above) or -resize your existing partitions so that both operating systems can -have boot partitions below cylinder 1024. - -You may blame IBM for the limitations of a 10 bit cylinder address. -"No one will have a disk with more than 1024 cylinders." I'm sure -someone said. |
