your original hardware configuration that didn't work.
---
Summary: Newfs crashes, requesting that blocksize be 32K
Cause: You have your SCSI controller configured to translate
geometries for disks >1GB in size.
Solution: Turn such translation OFF in your controller's BIOS
setup! FreeBSD has no problems with disks >1GB just
so long as the root partition starts and ends BELOW
cylinder 1024. This is a PC hardware limitation.
---
Summary: FreeBSD won't boot off the hard disk
Cause: Root partition does not start and end below cylinder 1024.
Solution: See solution for newfs crashes, or move your root
partition. This limitation holds true for ANY operating
system you wish to boot from your hard drive.
---
Summary: FreeBSD still won't boot off the hard disk
Cause: No boot code is installed in sector 1.
Solution: Chose the Write MBR (B)oot code in the FDISK editor.
---
Summary: Nope, FreeBSD's still not booting from the hard disk.
Cause: BIOS disk geometry different from that used when
installing FreeBSD.
Solution: With IDE drives, pay careful attention to the geometry
information that FreeBSD prints out when it's first
booting off the floppy. Use this geometry in your BIOS
setup or use the BIOS geometry when you install FreeBSD.
Either way, they have to match.
With SCSI drives, the values they report is most often
bogus and cannot be used. In this situation, the SCSI
controller is performing geometry translation and
it's probably wise to assume a default of 64 heads,
32 sectors and 1MB/cylinder. Use these values when
you install FreeBSD. See above comments concerning
newfs failures for more info.
