Switching from i2o_block to dpt_i2o

[Neil Gunton <neil@nilspace.com>]

Hi,

I am going to be rebuilding my colo server next week using the latest 
Etch netinst. The box has an Adaptec RAID card that has been using the 
dpt_i2o driver rather than i2o_block. I built this back in 2005, rolling 
my own kernel and going through quite a contorted process to get AMD64 
installed using dpt_i2o.

This time around I am hoping to install plain vanilla 32-bit Debian, and 
I am wondering how I can install using dpt_i2o rather than i2o_block as 
the RAID driver. I know about using modprobe, but I don't have 
experience of how to tell Linux to use one driver rather than another on 
a continuing basis.

So if Etch installs by default using i2o_block, how would I tell it to 
use dpt_i2o instead? Can I do this during the install, after which it 
will then use dpt_i2o automatically, or do I have to install first using 
i2o_block and then somehow convert down the line? If the latter, then 
how do I change the config to use the other driver?

The two drivers are apparently incompatible - you can have either one or 
the other installed, but not both.

Any clues much appreciated.

Thanks!
