学习NetBSD-挂载MSDOS分区
挂载MSDOS分区很简单:# mount -t msdos /dev/wd0? /mnt真的那么简单?还记得在安装过程中,到了"change BSD-disklabel partitions"的界面,居然在几次安装过程中有不一样的情况.
首先硬盘分区如下:
(wd0)ad0s1
128M
Fat32
# Grub(wd0)ad0s2
20G
UFS2
# FreeBSD(wd0)ad0s3
18G
FFSv2
# NetBSD理想情况下,MSDOS及UFS2的分区都会出现在安装NetBSD的"change BSD-disklabel partitions"界面上.背运的情况下,是没有出现.如果不出现的话,那么系统的disklabel就没有MSDOS及UFS2的分区信息,那上文的/dev/wd0?就无从说起.
解决办法:
1.fdisk /dev/wd0,留意红色部分.
