I think I have a slight understanding problem with your memory map, Ruud:
So your idejd4.bin is residing in... _what_ memory area? Is it completely
replacing the 1541 DOS from....$e000 to $ffff? Or $c000 to $ffff?
And you are using $1000 as a I/O interface to the harddisk, am I correct?
So I have to replace both kernal ROM chips in the 1541 with your own code, or 
how did you do it?
Please help us to make this point more clear.
