Simplest way to find out what geometry a disk pretents to have is to ask
fdisk, and since the only use for the information is when creating
partitions, then fdisk's opinion is really all that seems to matter.
Unfortunatelly there is also bios' view of the geometry, which is especially
a problem for boot loaders. Just another hint:
# lilo -T geom
bios=0x00, cylinders=80, heads=2, sectors=18
( 1.44Mb 2,880 sectors) C:H:S supported (PC bios)
BIOS reports 2 hard drives
bios=0x80, cylinders=527, heads=255, sectors=63 vol-ID: 2C731DD1
( 4.33Gb 8,467,199 sectors) LBA32 supported (EDD bios)
bios=0x81, cylinders=527, heads=255, sectors=63
( 4.33Gb 8,467,199 sectors) LBA32 supported (EDD bios)
(um yes my system is somewhat outdated, thats an adaptec scsi bios.
