Problem to save file on the hard disk! What I have to set to do it ?

[Matteo]

Hi Thomas,

The result after reading the partition table is "RESULT = 0"
I create the /mnt/hda1 too, with linux I can write and mount without problem on
hda1(FAT16). So why with RTEMS I can't do it ?

Have you some idea ?

Thanks
