hello all

development board.

now new patch has been added for ide disk driver.

can i use this driver for FAT file system pakage. what will i have to
do access the FAT floppy disk (and file sytem functionalities) using
ecos.



You can have a FAT filesystem on an IDE driver. However, from what i
understand about PC hardware is that floppy drivers don't use
IDE. There is another controller. Currently there is no support for
this controller in eCos.


'Long time ago' David N. Welton made a port of an existing FDC driver to eCos.
It doesn't have io_disk interface since it was done prior to disk/fat, but it is probably
a good starting point. You can find the sources in the ecos-devel list archives :
