FC2重新编辑内核心得

还是不行,看来我得重新再编译一次了!

如你真的想重新编辑的话，我还真建议你重新安装一次，把整个硬盘都用来安装LINUX，你的hda1 也不用FAT32了，都用ETX3得了，只是多分出一个/home分区就行了，完全呀，其实你有一个FAT32的分区可能会有WINDOWS下的病毒的:p :p :p

PS：没能帮你解决问题，脸红呀:% :%

我在FC2中编译了2.6.9,make 完了后就make install结果我没有选SATA的支持,就出错了,然后就重新配置了,在make后,就说什么bzImage已生成block (3,10),我拷贝到了/boot下,配置了grub.conf.

root (hda0,8)
kernel /vmlinuz-2.6.9 root=/dev/hda10
initrd /bzImage
我的/分区在hda10上,
可总是启动时说kernel panic -not syncing VFS Unable to mount root fs on unknown-block(3,10)

这是什么原因呢?????

#cp /usr/src/linux/System.map /boot/System.map-2.6.9
#cp /usr/src/linux/arch/i386/bzImage /boot/vmlinuz-2.6.9

然后再：
#cd /boot;rm -f System.map vmlinuz
#ln -s vmlinuz-2.6.9vmlinuz
#ln -s System.map-2.6.9 System.map

然后修改grub.conf 为：

title Fedora Core (2.6.9)
root (hd0,8)
kernel /vmlinuz-2.6.9 ro root=/dev/hda10

去掉：initrd /bzImage  这一栏，试试行不行！

老兄太客气了,你已经尽力了!呵呵!多谢了!!!!

我的内核已经是2.69,我害怕编译后出错,想保留原来的内核,同时编译后的内核也不要覆盖编译前的内核,该怎么办?另外,make modules_install 后是不是把原来的modules给覆盖了啊?

你可以下载一个2.6.9的源码包，用这个包来编辑新的内核，这样你就有两个内核可以使用了

经过64个小时的折磨，FC3还是没能在我的本本上安家，用回FC2,在这个过程中，发现一个长期以来就存在的问题，就是关于SELINUX的问题，在FC2时，我重新编辑内核后，在安装RPM时会有关于找不到SELINUX的问题，当时没想到是自己在编辑内核时有什么错误，在FC3里，我看了安装后的config，原来我是在编辑内核里给NO掉了SELINUX的相关选项.
     在重新安装了FC2并编辑内核后，启动了SELINUX后，发现在安装RPM时， 不会再有关于SELINUX的错误了，现在将linux-2.6.8.1的config在有变化的地方给大家说一下，希望不要发生与我同样的错误：

#
# Automatically generated make config: don't edit
#
CONFIG_X86=y
CONFIG_MMU=y
CONFIG_UID16=y
CONFIG_GENERIC_ISA_DMA=y

#

这一块基本上没什么变化，但要注意的是：
# CONFIG_POSIX_MQUEUE is not set 这项如果你在这里是NO，注意下边有一项也要NO，一会就看到了。

其中 ：CONFIG_HPET_TIMER is not set 这一项默认是YES，我没看懂这个选项到底有什么用，看说明是关于系统时钟的，不知道有什么影响，了解的朋友，给个说明吧，谢谢了！:%

说明：
1、我的本本（DELL 8500）不能使用APM，只好用ACPI，所以选项里只有ACPI的
2、CPU Frequency scaling  这个选项始终没有选过，不知道对CUP有什么影响，知道的朋友给讲讲吧，谢谢！:help :thank

这里默认的就差不多了，不过我将CONFIG_HOTPLUG_PCI=m 设置成M后，下面的选项全是NO。
