Interesting, I'll have to dig out one of my dead 1400 motherboards and check for the Intel floppy controller chip.

The floppy goes in the media bay of the PB5300. The 5300 media bay isn't large enough for a CDROM, but I have a ZIP Drive that works just fine in it. If can test your driver on the floppy in the PB 5300 and if you sent the source I may be able to figure out how to connect it to the external floppy on the 2300 Duo. > 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. > I believe it's documented in the existing code.

P.S. I have had some trouble compiling a stable kernel, could you provide the .config file you've been using? ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
