Edit image_mappings.txt to pre-assign disk images and computernames to client devices by serial number. To avoid syntax issues from missing commas it is recommended you edit this file with a spreadsheet or CSV editing app. Entries should be in the format 

Serial_Number,Computer_Name,Image_Name
1a2b3c4d,test-restore,image.wim

There should be no spaces in the serial number, computer name, and image name fields and they should be separated by commas. Computernames should meet Windows naming requirements and be 15 characters or less.

If you would like to set custom fields by their internal name, add them at the end after the image name. Custom fields need to be referenced by their internal names, followed by a colon, and then the value to set. The value for the custom field can have spaces in it, as illustrated in the example below.

1a2b3c4d,test-restore,image.wim,school:Washington Elementary,grade:5,classroom:218

If you have added a mode.reimage file to skip the PSImage main menu to go straight to imaging, you can still force a particular client to capture an image by setting the image name for its entry to "capture". This will allow you continue reimaging client devices without user interaction while at the same time still being able to capture a master image from your reference machine.

Launch edit_config.ps1 with "Run with PowerShell" for a text GUI to toggle the debug and imaging mode, as well as set the server DNS and base64 API token. You must specify a server DNS nad API token if you you will be
