I need a good 64 bit assembly book for beginners, can you recommend one, i'm kinda short on cash so I can only afford one. I have a few 32 bit books like -Linux assembly, high level assembly, and peter nortons assembly but I got to admit they aren't very good. I want to play around with turning my bios rom into a small operating system and messing with bootloaders and stuff. I only have a windows laptop so I guess i'll be using masm. question is their a 64 bit version? and where can I get it? also I need to practice on an 8 bit assembler where can I find one that is like masm or runs in an emulator? sorry to sound so needy lol, but I also am looking for the old intel cheat sheet, I think it was called the blue book or something(had it once) that list all the opcodes, operands and mnemonics ? the 8 bit and if it exists the 64 bit one. I got the amd 64 bit programming manuals what else do I need, i'm just starting to get back into programming after years away from it.
