Booting to New Kernel using Boot Disk
Hi,
I have windows 2k on the master hd and red hat 9.0 on the slave hd. I use a linux boot disk to boot up from the floppy drive. Recently, the red hat updater says that I have an updated kernel version that I should try to boot to. How do I do this? I don't want to install any bootloader onto the windows master hd. I want to either boot from the linux hd or use the boot disk. When I use the boot disk, it says that I can enter "linux <parameters>" What kind of parameters can I enter there? I tried typing the latest kernel version, but i guess that's not the correct parameters. On the other hand, I tried configuring the bios to boot from the slave drive. The only thing that shows up is "GRUB". I don't see a ">" prompt at all. Should I wait a while for this prompt to show up? Anyways, my goal is to boot into the latest kernel without touching anything from the master hd. Second, I want to create a boot disk that would use the latest kernel. How do I do this? Your help is much appreciated! Bernard:newbie: |
Before you upgrade do this:
dd if=/dev/hda of=/boot/boot.hda bs=512 count=1 This makes a copy of the MBR of your master drive. If it gets messed up you can restore it like this: dd if=/boot/boot.hda of=/dev/hda Or just this cat /boot/boot.hda >/dev/hda If you want to make a bootdisk: mkbootdisk /dev/fd0 X.Y.Z Where X.Y.Z is the version number of the new kernel. If you want to learn all about boot parameters then read the Linux Bootprompt HOWTO at www.tldp.org. |
