fedora 15所带的grub1默认只可以识别windows。

现在我的机器上还存在其他2个系统，必须手动引导。

[linuxsight@linuxsight ~]$ su
密码：
[root@linuxsight linuxsight]# cd /boot/grub
[root@linuxsight grub]# ls
device.map     grub.conf         minix_stage1_5     stage2
e2fs_stage1_5  iso9660_stage1_5  reiserfs_stage1_5  ufs2_stage1_5
fat_stage1_5   jfs_stage1_5      splash.xpm.gz      vstafs_stage1_5
ffs_stage1_5   menu.lst          stage1             xfs_stage1_5
[root@linuxsight grub]# vim menu.lst

添加红色区域代码。

这样可以引导slackware了。pcbsd也可以了。
