This chapter describes a slight variation on the basic method for installing a new disk image on a NetWinder. It is useful if there is not enough disk space on the NetWinder to hold both the compressed and uncompressed images.
This method requires sufficient space on the NetWinder to stored the new,
uncompressed disk image (about 650 MB for build #12). The NetWinder must
also have network connectivity (ethernet) - the
can used to configure IP address and other parameters.
In addition, a second computer is needed to hold the compressed disk image (about 250 MB). This can be another unix machine, or a Windows machine - anything capable of communicating with the NetWinder via ethernet. Configuration of the remote system is not covered in much detail here.
On the NetWinder, a disk partition should be freed up. This process is
described in detail in section 2.2 of the previous chapter. In the
following examples, it will be assumed that an empty partition has been
The `other computer' (hereafter called the server) also needs to be set up.
The compressed disk image should be downloaded to this server machine. The
image should then be made available to the NetWinder by putting it into an
NFS share (for unix systems) or into a public folder (for Windows machines).
Unix shares are normally listed in the
/etc/exports file, while
Windows handles it by right-clicking on the directory name and changing the
The NetWinder must then be configured for access to the (remote) compressed disk image. The process depends on the type of server being used.
The following commands show how to mount a remote NFS server so that theNetWinder can access its files. Replace
192.168.1.2 with the IP
address of the server and replace
/exportname with the actual name
of the exported filesystem. This must match the name given in the
/etc/exports file on the server.
mkdir /mnt/server mount 192.168.1.2:/exportname /mnt/server
To verify proper operation, use the command
ls /mnt/server - you
should see the compressed disk image in the listing.
In the case of a Windows machine acting as the server, you will have created
a shared folder with a name such as SHARE. You can access this share from
your NetWinder using the
smbmount command. Substitute the Windows
computer's name for COMPUTER, and specify your windows USERNAME and
WORKGROUP as well. You'll be prompted for your password.
mkdir /mnt/server smbmount //COMPUTER/SHARE /mnt/server -U USERNAME -W WORKGROUP
In case of difficulty, consult the
smbmount man page. To verify
that it is working correctly, enter the command
ls /mnt/server -
you should see the compressed disk image in the listing.
The proceedure for installing the image is nearly the same as that described in the basic method, except that the image now streams over the ethernet from the server system. The commands for installation are as follows.
cd /mnt/hda3 tar zxpf /mnt/server/YourImage.tar.gz
YourImage with the name of the compressed disk image that
you downloaded to the server. The process will nominally take about 10
minutes, but it depends on how much traffic is on the network. You can
monitor progress by switching to another terminal or window and using the
Please refer to sections 2.4 and 2.5 in the previous chapter for the post-installation instructions. Note that it is essential to update the etc/fstab file before attempting to boot the new image.
