[root@OVMM1~]# fdisk /dev/sdc
Thenumber of cylinders for this disk is set to 1566.
There isnothing wrong with that, but this is larger than 1024,
andcould in certain setups cause problems with:
1)software that runs at boot time (e.g., old versions of LILO)
2)booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
