the only thing now holding be back is the difference between info
provided by partition magic & fdisk. below is the output
of fdisk w/ difference w/ p-magic (wrt cylinder position) listed...
--------------------------------------------------
## fdisk ad0
******* Working on device /dev/ad0 *******
parameters extracted from in-core disklabel are:
cylinders=1299 heads=240 sectors/track=63 (15120 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=1299 heads=240 sectors/track=63 (15120 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 11,(DOS or Windows 95 with 32 bit FAT)
start 63, size 3280977 (1602 Meg), flag 0
beg: cyl 0/ sector 1/ head 1;
end: cyl 216/ sector 63/ head 239
The data for partition 2 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 3281040, size 6562080 (3204 Meg), flag 80 (active)
beg: cyl 217/ sector 1/ head 0;
end: cyl 650/ sector 63/ head 239
The data for partition 3 is:
sysid 28,(unknown)
start 9843120, size 7378560 (3602 Meg), flag 0
beg: cyl 651/ sector 1/ head 0;
end: cyl 1023/ sector 63/ head 239
# partition magic diff:
end: cyl 1138/ sector 63/ head 239
The data for partition 4 is:
sysid 15,(Extended DOS, LBA)
start 17221680, size 2419200 (1181 Meg), flag 0
beg: cyl 1023/ sector 1/ head 0;
end: cyl 1023/ sector 63/ head 239
# partition magic diff:
beg: cyl 1139/ sector 1/ head 0;
end: cyl 1298/ sector 63/ head 239
--------------------------------------------------
now question is: does the difference in cylinder numbers reported by
fdisk & partition magic make any, well, difference?
i have alredy read the man pages for fdisk & disklabel, just need
reassurance.
