Subject: 2 IDE controllers in one system

I have heart that it should be possible to have 2 IDE controllers 
in one ISA-system. I want to do that to allow having 4 IDE fixed disks 
in my system.

I've got a noname IDE controller on which you can set a jumper
for which ioports to use for the fixed disks: either 170-177
or 1f0-1f7. However, I can't see a jumper to set the IRQ channel.
So I'll have to change the IRQ by hand (soldering)

1) what is the default irq channel for the second controller
2) Is there any special reason why I shouldn't have 2 IDE controllers 
in general.
3) Are there any other sugestions.

(btw: the reason for me not to buy a SCSI controller is just lack of
money.)
