	First "Operation not permitted" is different from "Permission denied". 
The latter is from a security violation attempt (reading a file which
gives you no read permission).  The former is due to some other
mitigating circumstance.

	In this case, the zip drive is probably limiting the chipset.  Now,
I've never worked with a zip drive, but it perhaps can't do DMA, and so
limits the whole IDE channel.  As a test, try unplugging the zip drive,
and see if you can turn on dma then.  If so, the easiest way out may to
be purchasing an PCI IDE contoller, and moving stuff around.
