My main purpose was to document the link given to me by a friend who does user support for a local college. Before Vista the boot process was pretty simple, the MBR was one sector on sector 0, track 0 and it read the first sector of the target partition who took it from there. My experience with FreeBSD 7.0 to present has been that the install does not work with Windows 7. It appears that the MBR can still only have 4 entries. Windows 7 gets more by using extended partitions. Dell, the there can be only one and let it be Windows company, uses two small partitions for something. It may be that some of that underlying stuff is not needed but I had enough trouble without without making changes at that level. If FreeBSD can be installed in an extended partition, that would be a very useful howto. _____ Douglas Denault http://www.safeport.com doug@safeport.com Voice: 301-217-9220 Fax: 301-217-9277
