Booting The Cr Cd-Rom Boot Image - Novell SLRS 8 Admin Manual

2. Create the ISO image from the previously created operating system im-
ages. The
ture and all necessary boot manager files. Then an ISO image is made
using the mkisofs command.
For the example above, this step requires the following scr call:
scr create-iso mycd.iso
After the src call, find the mycd.iso image in the directory /tmp/mycd.

12.3 Booting the CR CD-ROM Boot Image

The behaviour of the POS clients booting from CD-ROM is similiar to the ac-
tions receiving the first and second stage boot image from a branch server. Fi-
nally the second stage POS image, for example, the browser image is installed
on the hard disk drive of the POS client. The partition information resides in
the config.image file located on the CD-ROM, which is normally created from
the LDAP entries from the administration server. For further CD-ROM boot-
ings, the installed browser POS image will be booted from the hard disk drive
of the CR.
Depending on the second stage boot image (minimal, java, browser, desktop)
which resides on the boot CD one should note the following restrictions:
The java and the browser image should only be used for diskful POS
systems. Otherwise the POS system needs to be upgraded with enough
RAM to hold the POS image.
For diskless POS clients the first stage and the second stage boot image
must fit into the available RAM
example, "VFS: Unable to mount root fs on ..." will be displayed loading
the second stage POS image.

Keep in mind that onboard VGA – depending on the used POS hardware – will also reduce
the available RAM disk space.
