You need to have at least one of the DOS partitions bootable. This is because of the BIOS limitations. Note the comment in the output of fdisk. This machine has a BIOS limitation of 504 MB. On an old IDE system, with a 2062 MB disk, DOS partition 1 is 400 MB and bootable, DOS partition 2 is 99 MB and bootable, DOS partition 3 is 399 MB and not bootable, DOS partition 4 is 1163 MB and not bootable. DOS Partition 1 is WINNT 3.51 OS DOS Partition 2 is FreeBSD 2.2.6 OS (/ and /var) DOS Partition 3 is WINNT 3.51 Data DOS Partition 4 is FreeBSD 2.2.6 /usr Study the outputs of fdisk, disklabel and df carefully. ======================================================== # fdisk ******* Working on device /dev/rwd0 ******* parameters extracted from in-core disklabel are: cylinders=4191 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=4191 heads=16 sectors/track=63 (1008 blks/cyl) Media sector size is 512 Warning: BIOS sector nuMegering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: sysid 7,(OS/2 HPFS, QNX or Advanced UNIX) start 63, size 819441 (400 Meg), flag 0 beg: cyl 0/ sector 1/ head 1; end: cyl 812/ sector 63/ head 15 The data for partition 2 is: sysid 165,(FreeBSD/NetBSD/386BSD) start 819504, size 204624 (99 Meg), flag 80 beg: cyl 813/ sector 1/ head 0; end: cyl 1015/ sector 63/ head 15 The data for partition 3 is: sysid 7,(OS/2 HPFS, QNX or Advanced UNIX) start 1024128, size 818496 (399 Meg), flag 0 beg: cyl 1016/ sector 1/ head 0; end: cyl 1023/ sector 63/ head 15 The data for partition 4 is: sysid 165,(FreeBSD/NetBSD/386BSD) start 1842624, size 2381904 (1163 Meg), flag 0 beg: cyl 1023/ sector 63/ head 255; end: cyl 1023/ sector 63/ head 15 ======================================================== # disklabel # /dev/rwd0c: type: ESDI disk: wd0s2 label: flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 16 sectors/cylinder: 1008 cylinders: 203 sectors/unit: 204624 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 61440 0 4.2BSD 0 0 0 # (Cyl. 0 - 60*) b: 81920 61440 swap # (Cyl. 60*- 142*) c: 204624 0 unused 0 0 # (Cyl. 0 - 202) e: 61264 143360 4.2BSD 0 0 0 # (Cyl. 142*- 202*) ======================================================== # df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/wd0s2a 29727 16266 11083 59% / /dev/wd0s4e 1154823 313363 749075 29% /usr /dev/wd0s2e 29639 1399 25869 5% /var procfs 4 4 0 100% /proc celebris:/usr/home/tomdean 2680202 1807493 658293 73% /mnt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
