Description

Represents a type of setting that is a string.

Notes

A string setting can contain spaces and other “special” characters that can cause problems during URI parsing. You can avoid these potential problems by requesting expansion as a uristring setting. For example, if you want to pass the SMBIOS product name to a boot script running on a web server, you could use

  chain http://boot.ipxe.org/demo/boot.php?product=${product:uristring}

This will ensure that any “special” characters are URI-encoded as necessary. For example, if the SMBIOS product name is “PowerEdge R210”, then the above command will expand to

  chain http://boot.ipxe.org/demo/boot.php?product=PowerEdge%20R210
