Abstract: The present invention makes it possible to quickly identify a place where a hyperlink is located in a document being displayed, and to design the document without caring about the indication of the location of the hyperlink. When a control thread is activated, a transparent sheet generation unit stores a transparent sheet into a transparent sheet storage unit; a thread activation unit activates a display thread and a visualization thread to cause a position identifying unit to identify a position where a hyperlink exists in a document being displayed; and to cause a marker drawing unit to draw a marker at the position thus identified in the transparent sheet. When the display thread is activated, a display unit reads a transparent sheet from the transparent sheet storage unit, and displays the transparent sheet in a visible state which has been stored in a visibleness state storage unit.

Abstract: At the time of installing an installation-targeted OS in a computer, a supporting tool in a supporting medium carries out the following operations on the supporting tool OS. The operations include: storing information in a response file; copying a unique device driver and a DOS system file from the supporting medium to a hard disk; copying an installation file from the installation medium to the hard disk; and updating the installation file with a security patch file downloaded from the download server through a network. Thereafter, an installer is booted up from the DOS system file to install an OS by use of the response file, the unique device driver, and the installation file.
