Abstract

A method and a device for checking the functioning of a computer are proposed, the computer in a normal operating state having access to the working memory via bus lines. For the purposes of checking, provision is made for an alternate memory and a switchover device, as a result of the switchover device the access of the computer being diverted such that access is not to the working memory but rather to the alternate memory. The content of the alternate memory can be influenced by a user. In the alternate memory provision is made for an auxiliary program, which is executed when activated by the computer and which makes available information concerning the internal operating states of the computer.
