I'm going to look into this this afternoon...
I spent a bit of time digesting the differences between the 2.2 and 2.4
versions of the ramdisk code, but have yet to successfully compile a 2.4
kernel (I need to migrate to my RedHat system with a newer gcc).
Does anyone know if there's a home for the ramdisk driver and possibly have
the URL?
