For example, if it's a Dell computer as shipped by Dell, then, yes, there is a potential problem. Dell ships its computers with three primary partitions already allocated and populated: a (hidden) service partition, the Windows XP partition, and the Windows XP system restore data partition (also hidden). That leaves only one unused primary partition entry in the Master Boot Record. If you use Norton Ghost to back up your Windows XP system, you will discover that Norton Ghost has an undocumented misfeature that will appear when you allocate that last unused partition table entry to FreeBSD (or to anything else). Norton Ghost expects to find an unused primary partition entry for its own temporary use while doing a full backup. (Grid only knows why it would need *any* kind of partition table entry, but it refuses to do the backup if it doesn't have one available.) The Windows XP system restore partition can be changed from a primary partition to a logical partition, and Windows XP doesn't appear to care. However, creation of a logical partition entry chain ties up one primary partition entry in the MBR, so converting the system restore partition alone doesn't buy you anything. If you then also convert the Dell service partition to a logical partition, Windows XP will no longer complete its startup procedure because there is at least one module (HAL.DLL) that its boot/startup routines will try to load from the service partition, which the startup routines aren't smart enough to find if it's a logical partition. Dell's technical support people eventually told me that the only way around that problem was to wipe out Windows XP and reload it from the CDROMs that they shipped with the computer. But if you do that, you may then have trouble reinstalling Norton Ghost and getting it to accept the fact that you do already have a paid-for license. Instead it may insist that it is just a demo version due to expire soon and reject the license number when you attempt to reregister it. Symantec, of course, is unreachable if you try to get them to support the license and software. But perhaps you do your backups a better way. Scott Bennett, Comm.
