I have my AT set up as 640K + 384K. The upper 384K is used as a disk cache to make disk accesses go faster. Basically, if something is to come off of disk and it is currently in cache then the cache driver pulls it from memory rather than making a disk access. If you do lots of little things, like using DOS commands, then this will speed up thing a lot. If you use big things like spreadsheets, or compilers then it probably won't help much. RAMDISK.SYS can be used or use one of the many PD caches available via bulliten boards. ...Dave Wasilew
