fdiskの使い方の詳細 ー SLAX 6.1.2のインストールを例にして ー

##slaxをCDブートする。
##パソコンの内臓ハードディスクに対してfdiskによる処理を行う。
root@slax:~# fdisk /dev/hda

The number of cylinders for this disk is set to 7296.
There is nothing wrong with that, but this is larger than 1024,
and could 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)
