Method of starting up computer by sequentially selecting memory module

The present invention relates to a method for selecting available memory module according to a certain order and making starting operation. Said method includes the following steps: loading parameters of basic input and output system of computer into first memory module of said memory module group; comparing said parameters with original parameters of said basic input and output system; if said compared result is coincident, making subsequent starting operation, else, said first memory module is a fault memory module, removing said fault memory module and loading said parameters into first memory module of next group, making comparison, so that making comparison according to order until the available memory module is found.
