This book really doesn't contain alot of useful information relating to today's machines and OS's. The first three chapters are useful, and perhaps the chapter on CD-ROM specs is helpfull too. Otherwise alot of what's in this book is useless or obsolete data. For instance: Who cares what the HDD geometry is of a 48 MB hard disc manufactured by Compaq over ten years ago. Although nobody uses DOS anymore, the book does cover all DOS commands up to Version 6.22. Usefull if you threw away your old DOS manuals when Win 95 came out. Pay little attention to the photos of those CPU's they show. I noticed the Intel i80186 is missing. A very rare chip indeed - but I had one. As well as my Celeron 300a and who nows how many more. One GLARING and INEXCUSABLE omission from this book is anything relating to BIOS of any sort. This is sufficiant cause to remove this book from all bookstore shelves entirely!
So if you do make the mistake of buying this book - it won't be a total waste of money. ( )END
