The "USB stick Boot configuration tool"(gpusbst4.exe) is a tool for configuring USB flash drive for starting and executing the "Boot up Erase Program".

As you know, "gpset4.exe" has same function, but this program can be executed with user privileges (administrator privileg is not required) and is useful for distributing USB flash drive boot environments within your company.

Options for "Boot up erase program" are loaded from the data file "gpdata.pac" and you can not set with this program.

If the USB flash drive has partition like usual HDD ("HDD type"), legacy (BIOS) booting with the USB flash drive is NOT possible. Only UEFI startup is possible.
If legacy (BIOS) booting is required, run "gpusbst4.exe" with "administrator privileges" and configure.

*If the USB flash drive is "large FDD type" with no partitions, legacy (BIOS) boot configuration is possible with general user privileges.
*The difference between "HDD type" and "large FDD type" is the difference in whether or not partitions are created, and is not specific to USB flash drive hardware.
*Depending on your PC, you may not be able to start the PC if it is either an "HDD type" or a "large FDD type."

Executing "USB stick Boot configuration tool"

The "USB stick Boot configuration tool"(gpusbst4.exe) that runs on Windows can be easily started and executed without any installation work.

You can boot directly from a CD-ROM, network folder, etc., double click "gpusbst4.exe" to start it.

*License file "license.gp4" is requierd in the same folder as "gpusbst4.exe".

Confirmation of "Data file" existence

The "Data file" (gpdata.pac) is required in the same folder as gpusbst4.exe or in the [data] folder at the same level as gpusbst4.exe.

For details about "Data file", see "Executing "Startup environment creation tool" .


Storing option values for "Boot up Erase program" to the Data file

If you want to specify options for the "Boot up erase program", you must save them in the data file (gpdata.pac) in advance.
This program configures the USB flash drive using the saved option values.

By specifying and storing options in advance in the System department, internal users can create USB flash drives with the same specifications without having to be aware of the options.

For details on how to specify and save option values, see "Customizing/Setting data file".
Whether "Initial, changeable'' or "Fixed", have no effect on this program.

*However, when running with administrator privileges, the settings of "Initial, changeable'' or "Fixed" will be valid for the USB flash drive type.

Operation of configuring USB flash drive

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.
Then click [Execute USB].

Warning !

* Please note that the USB flash drive is initialized by the setting process and the inside is erased. * Please use a USB flash drive of 64GB or less. Anything larger than 64GB will be treated as an erase target drive and you will not be able to write logs. Also, when automatic erase is set, it will be erased automatically. * USB flash drives that are encrypted and those require a password at the time of use cannot be used for booting.

Other settings procedures are almost the same as "Setting bootable "USB flash drive".
Please have a look at this.

After selecting a USB flash drive, the following message may appear.

In this case, legacy (BIOS) booting using the configured USB flash drive is not possible. UEFI boot only.

If legacy (BIOS) booting is required, settings must be made using one of the following methods.
・Run "gpusbst4.exe" as administrator and configure. (Both "HDD type" and "large FDD type" are possible)
・Run "gpusbst4.exe" as administrator and configure for "Large FDD type". After that, settings can be made with general user privileges with this USB flash drive.

*Depending on your PC, you may not be able to start the PC if it is either an "HDD type" or a "large FDD type." In that case, you will need to "Run as administrator" and change it to a bootable type.
*These operations can also be performed using "gpset4.exe".

"Run as administrator"

If you run "gpusbst4.exe" as administrator, the flowing screen is displayed.

The "Config Type" selection will be displayed, and you can specify it as you like.
