 I got a zip drive working on Alpha the other day.  Since there was a bit
 of non-obvious stuff to do, here's how to do it (and why)

 The ZIP driver assumes that the parallel port is sitting at 0x378
 on Intel boards.  This isn't necessarily the case for Alpha machines.
 Under Alpha BIOS, here's how to figure out what the actual address is:
         Go into system setup
         Select Display System Configuration.
         Select Integrated Peripherals (for some Alpha boxes)

 This showed the parallel port i/o address at 0x3bc for the machine I
 was connecting it to (a prototype).  At this point, you can either
 modify the parallel port driver initial value, or you can override
 the default in the kernel at boot time:

 MILO> boot sda2:vmlinux.gz ppa=0x3bc
