I'm not sure if Rod would recommend them, but they seem I would _highly_ recomend them, along with the new books on PCI (just picked up the Third Edition of that one that covers PCI 2.1) this week. Infact the whole MindShare series should be in any PC engineers libarary as a ``must have'' item. > to be good, and would have cut this thread short since they go into > all of this, as well as all the bus cycles, bus arbitration, memory > systems, etc. As someone who has traditionally been a little weak on > PC hardware, I got lots of useful information from them. > > >From reading them, I beleive that Rod is correct in his calculations, > although they did seem to omit the memory refresh cycles that are > stolen at least from the ISA bus (I'm not that far into the EISA book > to know), but if I understood and recall correctly, they are << 1% of > the bus bandwidth and can safely be ignored. > > Anyway, if anybody else has seen/read these books and has an opinion, > please let me know (and the list, if you think it relevant). You got mine, they are the gold books of this stuff, a little late for some one like me who was there before the first XT ever shipped, but sure wish we had them back then!! > On a related note: Is there a good FAQ for this information?

Someplace I have a list of reference material I was trying to collect for the FreeBSD library, but can't seem to find it, perhaps it is in my freefall account some place :-(. > > Warner > -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
