Set up and create the host function to start PC's to be erased using network boot (PXE) and execute the erase program.
Here you can create a bootable CD image file or configure USB flash drive.
Just by booting your PC using this CD/USB flash drive, you can build a host (server) that includes all of the following functions.

・Host function for network boot
・Loading the erase program on network booted PC's
・FTP server for the erasure program to write logs
・NTP server for time synchronization with network booted PC's

Please set one of the following.

*A check will be placed to the left of the currently valid item.

NetBoot CD-Rom image file to create

Specify the file to create. Enter the file name (full path) directly from the keyboard, or press the "Ref." button to specify the file.

Select USB flash

Select the USB flash drive to be set from the list.
* A list of USB removable drives is displayed.

When you make a selection, information such as the current setting type is displayed.

* Please note that the USB flash drive is initialized by the setting process and the inside is erased.

gpdatahost.pac - [Write]

When there is a valid network boot data file, the version will be displayed as shown in the image above.

The [Write] button allows you to write the values set in [Detaile conf.] to the data file (gpdatahost.pac).

The written value will be displayed as the initial value/fixed value the next time you start the "Startup Environment Settings Tool". Whether to use a changeable initial value or a fixed value depends on the "Fixed value" specification in "Customizing/Setting data file".

This is a convenient function when you use it frequently or when you want to specify a value and distribute it. *Here, only data related to "Network boot host settings" is written to (gpdatahost.pac). Other setting values are written to (gpdata.pac) by operating from the "Customizing/Setting data file" screen.

Data file

The currently valid data files are displayed.

Clear Values

If you check and execute "Execute Write", the values written in the data file will be deleted.

Execute Write

Writes values to the currently valid data file.

Host PC network settings
------------------------------
Settings for the host(server) PC itself.

IP Address/Subnet mask/Gateway/Name server

These are address settings for network boot host PC.
Please specify the IP address (IPv4), subnet mask, default gateway, and name server.
Default gateway and name server are not required. Please specify only if necessary.

Enable NTP client

Check this box if you want to synchronize the host time with an NTP server.

NTP server

If you check "Enable NTP client", specify the server to synchronize time with.
Specify by IP address (IPv4) or server name.
When using a server name, it is necessary to specify a "Name server". 

Timezone

If you check "Enable NTP client", specify the time zone of the PC.
Specify between GMT-12 and GMT+12.
For example,
   San Francisco (USA) , "GMT-7"
   New York (USA) , "GMT-4"
   Berlin (Germany) , "GMT+2"
   New Delhi (India) , "GMT+5"
   Tokyo (Japan) , "GMT+9"

Services on the host
------------------------------
Service settings for network-connected client PCs.

Network boot (PXE)

Network booting uses a DHCP server to distribute IP addresses and other information necessary for booting. Therefore, if you want to use the network boot function, you must enable it and set the DHCP server information.
Here, set the IP address range (IPv4), subnet mask, gateway, and name server information distributed by the DHCP server. Gateway and name server are not required, but should be configured as needed.

FTP server

It can be used as an FTP server for saving erase logs over the network.
There is no need to enable it if you do not use it. Network booting is possible without enabling it.
If used, please specify User ID and Password for connecting to the FTP server.

When you press the "PW" button, the password you entered will be displayed. Press it again to display "*".
However, "PW" can be displayed only when entering a new character or after clearing all characters.

NTP server

It can be used as an NTP server when synchronizing the time with the PC to be erased using network boot.
There is no need to enable it if you do not use it. Network booting is possible without enabling it. 

Timezone

If you use NTP server, specify the time zone, between GMT-12 and GMT+12.
For example,
   San Francisco (USA) , "GMT-7"
   New York (USA) , "GMT-4"
   Berlin (Germany) , "GMT+2"
   New Delhi (India) , "GMT+5"
   Tokyo (Japan) , "GMT+9"
 
If you check "Enable NTP client", please use the same time zone as NTP client.

Execute [Host]

Execute creating a CD-ROM image file/setting USB flash drive.
* Processing will take some time. Please wait until the end message appears.

For "Points to note in the setting procedure", see Setting bootable "USB flash drive".
The procedure will be similar.

Specifying erase program options

This network boot host can boot network-connected PC's and let ths PC's execute the erase program.
The erase program to be executed is the same as "Boot from CD/USB flash drive", and options can be specified in the same way. For details on specifying options, see "Common options".

For example, when you set the network boot host address etc. in "Detail conf." as shown in the image above, and specifying the "Network" option of the erasure program as shown in the image below, the following feature will be enabled.

・Obtain address by DHCP from the network boot host
・Write log to the network boot host using FTP
・Time synchronization with the network boot host using NTP
