This book is disappointing to say the least.... No reference on AT&T syntax etc. The information presented is rather disparate & lacks coherency, very confusing & difficult to excogitate. As a neophyte, I would like to be able to access all references in a central location, where I can check the assembly command; see it's syntax; look up the CPU instruction; check it's syntax & see how it relates to the register in question, whilst at the same time I want a brief description of the register; what it's name means & what it does; have a list of system call numbers; their descriptions & functions etc. Kernel internals were briefly discussed but left much wanting. Free documentation served me much better. If you know what you want it's all availible online.
