If this file is not available and cannot be loaded, it means this is a new
cash register that can be immediately registered.
A new cash register is registered in two steps:
An optional alias name can be set for the new cash register. During
image creation of one of the boot images, you can enable the system
alias setting via the POSSetAlias feature module. By default, there
is no question for the system alias name.
A control file is uploaded to the TFTP servers upload directory:
/tftpboot/upload.
hwtype. MAC Address
The contents of the file correspond to the cash register hardware type,
the BIOS version, and the cash register alias name. Further information
about the control file can be found in Section 15.6.2.
After the upload, the cash register branches off into a loop in which the
following steps are taken:
the DHCP lease file is renewed (dhcpcd -n).
a new attempt is made to load the file config. MAC address from
the TFTP server.
if the file does not exist, there is a 60-second wait period before a
new run begins.
If the configuration file does load, it contains data on image, configu-
ration, synchronization, or partition parameters. For more infomation
about the file format of the configuration file, refer to Section 15.6.1.
8. The PART: line in the configuration is analyzed. If there is a PART line
in the configuration file, the following analysis takes place:
A check is made using the image version to see whether any local
system needs to be updated. If not, local boot process continues
immediately. No image download occurs.
No system or update required: cash register hard disk is parti-
tioned.
9. SYNC: line in configuration file is evaluated. If there is a SYNC line, the
indicated file is downloaded via TFTP. The only value the file contains is
the number of seconds of wait time required before the multicast down-
load of the cash register image starts (sleep). If the file is not present, it
proceeds immediately. Otherwise, it waits for the indicated time.
10. Indicated images are downloaded with multicast TFTP.
