I (re)discovered a great book about PC Assembler, which you can get for free from here. Printed it out yesterday, 197 pages, great stuff. Had this book some time ago, but I lost the PDF file. Finally found it again :) This is really an excellent book about ASM, although it does not cover SSE/MMX (but after reading it you should know enough that using those won't be a problem for you). Thanks for making this available for free!
