Whenever using DOS on anything more recent than a 386, you shoul ALLWAYS
use /testmem:off since himem.sys uses a really small block size for memory
testing; then since a 486 has 8K of cache memory and anything released
since then has even more on chip cache, then himem.sys will only test
your cpu's on chip cache, an it will probably do that in a less than
optimal way. Hence anything but /testmem:off is a waste of time.
