Me too and since most modern hard drives using DMA with more than 2mb of cache ram of their own , dedicated to storing small files pending any write delays, ramdrives are inconsequential for the purpose suggested, we are looking at saving fractions of milliseconds at best it would be better to change IE's start priority and ensure the RTC (real time clock) is using IRQ 8, but I agree it was a very good presentation.

Also depending on what starts in which order when booting any Win from 98 onwards will reassign temp\internet directory back to the default location if it doesn't start the ramdrive in the correct order, drive letters are assigned on every boot and you could find you have wasted memory creating a ramdrive that's not being used, unless you want to manually start the ramdrive and change the cache location for each session.
