HI, yes I am working on it. I have a separate wini and floppy driver (separate Tasks) running on the 8490. I just started the 6250 code this (last) weekend. I have done a lot of the ground work, i.e. in getting the wini & floppy to share a controller, and from there, to share the common resource (when they need to program the controller they have to select it). My floppy and wini seem to work with my OMTI controller. I have also tried to make the drivers use dynamic storage for command buffers etc., since this will be required whenever (if ever) we get a multi-threaded FS. I started with Bruce's drivers. I have split them into 3 levels: sc_wini.c sc_floppy.c | | +-----------------+ | scsi.c | +--------+--------+ | | scsi_8490.c scsi_6250.c The upper modules look after O/S-specific stuff. scsi.c looks after scsi stuff, and the lower modules just perform a bus transaction (set) with its channel. Unfortunately, I do not have much time (I am in a start-up company), but I am plodding along. I also intend to add support for a scsi printer. Cheers, Des.
