Re: [Nubus-pmac-users] Powerbook 1400 Media-Bay

Hi Ray,

good to hear.
I have already ported the floppy driver but it doesn't work.
It recognizes the floppy drive when booting with the CD-ROM in the bay  
and then inserting the floppy drive when in Linux.
On mounting /dev/fd0 the head of the drive begins to move and then the  
system freezes completely.
I tried with Daniel's C code and also used a demo of PortAsm68K  
(http://www.microapl.co.uk) to port the 68k assembler code to PPC  
assembler.
Both give the same results.
As I have already mentioned the PB 1400 in fact uses a standard PC  
floppy controller, and the SWIM II might only be emulated.
The apple developer documentation says that the floppy controller is  
the only difference to the PB 5300.
So maybe the driver will work with the PB5300 (you might need an IDE  
drive for the media bay, i.e. a ZIP drive).
Unfortunately I didn't find the I/O space of the floppy controller -  
maybe it is directly connected to the SWIM II controller and therefor  
not accessible for the CPU.

On the m68k mac linux mailing list I found that Laurent Vivier has  
already ported his driver to the 2.6 kernel; didn't you know that?

Do you have any problems with hotswapping of the different drives?

Tobias
