you want as much stuff in RAM as possible
One would think.
I just spent two days trying to reload a circa 2001 Windows XP onto new hardware and can't figure out why it keeps complaining about corrupted files, googled to find out the uncompress app of that era can't handle a large memory space as I have now (go figure!). Took out 1 memory stick and now the install proceeds normally!
Well I'd be darned.
(OK go ahead with the Windows jokes)
