Hallo allemaal,

This version enables you to use images, as much as your harddisk can 
contain. The use is quite simple, just use "@Z:xxxx" were xxxx is the 
number of the image. Everey image needs 768 sectors and when knowing the 
size of your harddisk, you know how many images you can store.
Remark: if you never used the choosen image before, don't forget to format 
it first!

If you have questions, you know how to find me :)


As you can see I abandoned the idea of using a subdirectory liked 
structure. The main reason is simple: this was a quite quicker hack :) I 
have now something people can work with for the moment. Another reason: I 
myself don't like this subdirectory like structure that much. But once I 
have the subdiretories running fine, I program an image structure as well.

I also want to expand this version a bit: @Y should give you a list of 
already available images. And people who already worked with the previous 
version can use an extra function that searches for these already installed 
images.


Another good news: I solved the format bug. It seems that the formatting of 
the whole track was the problem. But I still haven't found out why the 
drive behave so weird when formatting the image for the second time.
My solution is to format only one sector par interrupt. And that worked out 
fine enough, The problem is that formatting is as fast as the original 
JiffyDOS format, about 2.5 tracks/sec. 
If people are thinking about suing the original format routine and taking 
the bug for granted: I only found out this weekend that this buggy routine 
doesn't format all sectors as it should. Most of the time wrong values were 
writen to sectors, or nothing written at all.
With the above speed, I wonder what it is to format tracks that are 10 
times as big (16 MB version) or when using the big FS ??? I/we have to find 
another solution.
