[Linux-ia64] build a bootable kernel

[Linux-ia64] build a bootable kernel

[dai yiyang]

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,
DaiYiyang

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.

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

   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
 
>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.
