I have got my a1200 booting using install 3.1
on step 10:
click on the "Read Configuration" button.
I get "Unit is not a disk (type 7)"
the size is wrong 211Mb (got 256Mb card)
To commit your changes to the hard drive, click on "Save Changes to Drive"
I get "Error 3 on write"
what am I doing wrong?
