Hi :

I have build a 2.5.39 kernel under redhat 7.2 use "make vmlinux" , the
output file vmlinux is 55M! and seems cannot be loaded by elilo .
Per my check the original kernel file default installed on the system is
only 1M , I think it should been compressed .
Anybody can provide me the right step to build a bootable kernel under
ia64 ?

Do "strip vmlinux"
or delete -g option in Makefile
and then compress the kernel with gzip or bzip2 if you want.

make compressed

will build you a stripped & compressed kernel in vmlinux.gz.

thanks for your help
the kernel file has been built .
but how to load the kernel during system boot time ? I have edit the elilo.conf file add the new kernel's path . but the the system halted at "umcompressed kernel ......ok ."

I think its due to I do not install the bootloader , but I dont konw how to handle it :(

Regards,

What kind of machine are you trying to boot? What is the .config file used to build the kernel? What is the content of elilo.conf?

With this information I may be able to tell you what's wrong.

Thanks.

What kind of machine are you trying to boot?

I use a compaq proliant DL590 ( Itanium -700Mhz)

What is the .config file used to build the kernel?

I dont have the experience on build a ia64 kernel , so I use the
common config
My concern is in "IA-64 System type" wehther I should choose
DIG-compliant or generic
I use generic in my kernel configuration

Quoted 1 line

What is the content of elilo.conf?

           image=vmlinuz-2.5.39
		label=linux-2.5.39
		initrd=initrd-2.5.39.img
		read-only
		root=/dev/ida/c0d0p3

     the section for my new kernel was copied from my previous kernel

section , I think it should be correct.
