Thanks. It doesn't hang anymore but now how do I
mount:
RTEMS SHELL (Ver.1.0-FRC):/dev/console. Mar 12 2008. 'help' to list
commands.
SHLL [/] # ls /dev/
-rwxr-xr-x 1 root root 0 Jan 01 00:00 console
-rwxr-xr-x 1 root root 0 Jan 01 00:00 ide0
2 files 0 bytes occupied
SHLL [/] # mkdir /mnt
SHLL [/] # mount -t msdos /dev/ide0 /mnt
mount: mount failed: Block device required
SHLL [/] #
And for those who haven't tried the RTEMS shell recently, that is
a command line interface with the recently added capability to
execute simple script files. :D
