What is the most complete guide to Win98

What is the most Complete guide to learn Windows 98 in and out? How about to study for the MCSE Windows 98 test? I’m mainly looking for books to study but if there are other sites or articles that maybe be helpful that would be great. I’m also looking for material with good explanations of the startup files and common drivers such as himem and emm386 etc. Actually hopeing a good guide would cover that.
