In my experience the root partition must not only be reachable by the BIOS, but be contained entirely within the reachable limits of the BIOS, i.e. <1024 cylinders or whatever. On my 1GB drive I have a small root which is used to mount the rest after the BIOS has been blown out; here's the fdisk info for completeness. Neil ******* Working on device /dev/rwd0 ******* parameters extracted from in-core disklabel are: cylinders=2099 heads=16 sectors/track=63 (1008 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=2099 heads=16 sectors/track=63 (1008 blks/cyl) Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 0 is: sysid 77,(unknown) start 263088, size 676368 (330 Meg), flag 0 beg: cyl 261/ sector 1/ head 0; end: cyl 931/ sector 63/ head 15 The data for partition 1 is: sysid 165,(FreeBSD/NetBSD/386BSD) start 939456, size 42336 (20 Meg), flag 80 beg: cyl 932/ sector 1/ head 0; end: cyl 973/ sector 63/ head 15 The data for partition 2 is: sysid 165,(FreeBSD/NetBSD/386BSD) start 981792, size 1134000 (553 Meg), flag 0 beg: cyl 974/ sector 1/ head 0; end: cyl 1023/ sector 63/ head 15 The data for partition 3 is: sysid 6,(Primary 'big' DOS (> 32MB)) start 63, size 263025 (128 Meg), flag 0 beg: cyl 0/ sector 1/ head 1; end: cyl 260/ sector 63/ head 15
