(the right number is 1278=16*63*2477*512) no, 1MB is 1024 x 1024 = 2^20 = 1048576 bytes 16*63*2477*512 = 1278369792 bytes 1278369792/1048576 = 1219MB alooks like 2.0 version? did you both select 'whole disk' AND a boot manager? the two options are incompatible under 2.0 and result in a similar problem.. failing that make sure that your geometry is the SAME as what the BIOS expects AND that your last block is the LAST BLOCK OF A CYLINDER according to the BIOS geometry. > > I wonder if that's what is breaking the boot manager..... no > If FreeBSD is the only OS, then don't install the boot monitor. > julian +----------------------------------+ ______ _ __ | __--_|\ Julian Elischer | \ U \/ / On assignment | / \ julian@ref.tfs.com +------>x USA \ in a very strange | ( OZ ) 300 lakeside Dr. oakland CA. \___ ___ | country ! +- X_.---._/ USA+(510) 645-3137(wk) \_/ \\ v
