RE: [Xen-users] Compiling Kernel with raid driver for my Dellpoweredge 2850 RAID Controler

["Nicolo" <nicolo@xxxxxxxxxxxxxxx>]

In fact, my original kernel is 2.4.27-2-386 version using megaraid2 mod in
my debian sarge.
It will be installed with cdrom so I don't know if it's run in mod or inside
the kernel ... how can I see it ?

My xen kernel is a 2.6.16 version ... and doesn't have megaraid2 in .config
file
I can't make init fileinitrd.img , because megaraid2 is a 2.4.27 mod and not
a 2.6.16 ...
Error : FATAL: Module megaraid2 not found.

I have the megaraid2 module here :
/lib/modules/2.4.27-2-386/kernel/drivers/scsi/megaraid2.o

I don't know if I have to do :
depmod 2.4.27-2-386
mkinitrd -k -o /boot/initxen.img 2.4.27-2-386

or
depmod 2.4.27-2-386
mkinitrd -k -o /boot/initxen.img 2.6.16-xen

or
depmod 2.6.16-xen
mkinitrd -k -o /boot/initxen.img 2.4.27-2-386

or
depmod 2.6.16-xen
mkinitrd -k -o /boot/initxen.img 2.6.16-xen


--builtin=xxx ??? what would you like to do ?

Sorry I'm newbi in kernel building ;-)

Thanks
Nicolo

Do depmod first?

Do you actually have a  megaraid2 module? [Or is it builtin to the
kernel - in which case use --builtin=xxx to tell mkinitrd that].
