The PERC 2 has the BIOS enable for the machine start with its, OK?
The new card PERC 3/DC has the BIOS disable, because this card must connect
with the POWERVAULT only, not with the internal disk
the machine, where is the system, OK?

Well, I change the scan sequence but the same thing

Linux stop when the Kernel in loading and start to print menssages in the

I don´t now how set to boot with the PERC 2, but i think what that is done!

The problem is what when the PERC 3/DC is in the machine the kernel stop
when is starting

This is my /etc/modules.conf:

alias parport_lowlevel parport_pc
alias eth0 e100
alias scsi_hostadapter aic7xxx
alias scsi_hostadapter aic7xxx
#alias usb-controller usb-uhci

The bios has a scan sequence which is set low to high or high to low of the
pci devices.  You can swap the scan sequence around and it should work.

I assume you mean PERC 3/DC.  It's an add-in card, the 3/Di isn't.

1) BIOS must be set to boot from the PERC2, not the PERC 3/DC.  This is a
config option in the Setup screen available immediately after power-on.
2) Linux must think that the PERC2 is your boot device.  This means that
/etc/modules.conf needs to list the aacraid driver first, the megaraid
driver second.  If that's backward, it won't work.  Fix that, remake your
initrd, and reboot.
