Yes, you can have four. You should have an ide controller with which you can
change the io adresses (the irq can be changed 'manually'). You just
need the correct driver. 
No it won't work under dos, because the bios only supports one controller,
at io 0x1f0, irq 14.

I am using the barsoom wd driver but still have some problems: the first drive
in one copntroller is both recognizes as the first and as the second driver
at the controller, while the second disk seems to be ignored. When looking
at the probing and attaching code in both the stock wd driver and the
Barsoom beast, I dont see a difference at first sight, but I didn't
look closely yet.
