But then it was late and I could have made an error somewhere. But that was the commando I used. This system has an extra 40Gb disk in it. I'll runs some test on that as I now have a config that does do what I need it to do. although the amd64-root slice is far away from all the other amd64 slices: Order on the disk: ad0s1a / i386 ad0s1d / amd64 both are below the 1Gb mark ad0s1b swap ad0s1e /var i386 ad0s1f /tmp i386 ad0s1g /usr i386 ad0s1h /home1 ad0s2a /var amd64 ad0s2d /tmp amd64 ad0s2e /usr amd64 ad0s2f /home2 ad0s3 win 2K primary partion above 100Gb mark ad0s4 win XP64 in extended partition Which is more or less also the order of installation Then I booted the i386 CD again, but the FBSD boot manager there. As expected it does not want my trick of /-amd64 as ad0s1d. But it does boot win2k which gives me the Win bootselector for 2K of XP64. So I installed GRUB as bootmanager. Which does allow me to boot ad0s1d for amd64. And it does the Win stuff as well. > > And it is not very clear to me that this would allow me to boot > > win 2k and/or win 64XP. > > You do realize that both of these can blow away the MBR and replace > it with Microsoft software?

It also requires on the do some hassle with extracting the MBR's with the correct active flags. Which I fumble for shure, keepingme even longer from the street. :) But for now I'm a happy camper. --WjW
