Happy Thanksgiving all! I have a couple of questions here. Thanks very much in advance for any replys. 1) Why is it that the ROM in my PC is so much slower than my RAM memory? That is, my read/write memory is 60ns, while my ROM is something like 120ns. 2) I've been trying to picture exactly how the memory in my computer is actually accessed. I assume I have 32 address lines coming from my 486, but do these lines go into something like a decoder with 2^32 out lines? I'm not an expert here, but I do seriously doubt this. If it gets too complicated to explain, then please let me know where I may look for this info. Again, thank you all for any help! -- Ross Hayden haydedr@wkuvx1.bitnet What do you get when you cross Captain Picard and Dirty Harry? A starship captain walking around saying, "Go ahead punk, make it so."
