Hi,

Your kernel download URL is truncated so I can't make any comment on that however assuming you are running a pentium class intel box (hence the i686 kernel) then you are almost correct...

Use:
rpm -ivh kernel-2.4.20-20.9.i686.rpm

-i rather than -U so that you install a new kernel rather then upgrade your current one. This way, rpm will update your boot loader and if the new kernel doesn't work then you can still boot the old kernel. -vh = verbose with hash marks for status.

If you're short of space, one you are sure that the new kernel works you can uninstall the old kernel using rpm -e.

if you want to boot the new kernel by default, edit your bootloader file (/etc/grub.conf if you're using grub) to specify the correct default kernel (1st stanza = 0 not 1).

Good luck!

Dave

PS - the 'up2date' utility can do this for you and is well worth looking at. Run the command 'up2date' or go to
http://www.redhat.com/software/rhn/update/

do an 'rpm -ivh newkernel.rpm' first. reboot and use it. if everything works fine on your system, stick with it. if you have probles, revert to the old one.

try using 'up2date kernel'.

you might not need bigmem and smp kernels - they are for production and multi-processor servers.

hello
thanks for urs reply, before urs urs reply i try this following command.
rpm -U kernel-2.4.20-20.9.i686.rpm

and aftre reboot , linux come in xwindows and no error and with thsi command: uname -r its retun latest kernal version
2.4.20-20.9
what does mean, is it ok and updatet or still i will have to use
rpm -ivh kernel-2.4.20-20.9.i686.rpm command.

thanks

Hi,

it looks as though it has worked. Your gamble has paid off.

-ivh is safer than -U as you have options if it doesn't work but it has worked so congratulations, you have upgraded your kernel.
