I forgot to state that this was amd64. The thing is, that the installer actually gets the right number - 1249664157: Disk: aacd0 Partition name: aacd0s1 Free: 1249664157 blocks (595GB) This is how the disk is configured after my manual change using 'disklabel -e' to /var: Part Mount Size Newfs Part Mount Size Newfs ---- ----- ---- ----- ---- ----- ---- ----- aacd0s1a <none> 512MB * aacd0s1b swap 4056MB SWAP aacd0s1e <none> 512MB * aacd0s1d <none> 10240MB * aacd0s1f <none> 577GB * If I delete these partitions and manually enter the sizes in the installer, an extra (nonexistent) 3GB appears: Part Mount Size Newfs Part Mount Size Newfs ---- ----- ---- ----- ---- ----- ---- ----- aacd0s1a / 512MB UFS2 Y aacd0s1b swap 4056MB SWAP aacd0s1d /tmp 512MB UFS2+S Y aacd0s1e /usr 10240MB UFS2+S Y aacd0s1f /var 580GB UFS2+S Y > Could you perhaps add debugging printf()'s to Int_Open_Disk() to try to > trace what is going on? I'll see what I can do. Ian -- Ian Freislich
