NIOS 1! problems

Hi,

I got an altere excalibur nios development kit (apex20KE fpga), with NIOS 1.0 1.1 and 2.2 SDK and HDK, I also got quartus 5 installed. I got these things from a friend and he didn't have the original disk with it.

Now I have a few problems with it in my windows XP virtual machine, I can see my NIOS 2.2 in Quartus sopcbuilder 2.7, I can make a design/configure the nios as described in the tutorial that comes with the SDK/HDK.

The problems start when I try to generate the design (even when I just open a reference design, open the nios and regenerate it).

It gives an error when generating the .c files for the peripherals, "nios_map.h: can't find file or directory" the same for nios_peripheral.h...

anyone any idea? or any idea where I can get the latest complete nios 1 software?
