That was my guess: "maybe some of them can be even seen as 'obsolete' by now".

Actually, it was a bit surprising to me, that I still need a software
cache, while using hardware, which - like for DOS requirements - is
really very fast. Unfortunately, using no caching at all, I noticed
pauses (3-4 seconds), that occur although not to often, but frequently
enough to be irritating (the controller's LED is on at that time).
Well, perhaps the NVIDIA SATA isn't the best fit for DOS.

I agree, thanks for providing such nice thing. :)

Just out of curiosity ;) , made a "quick search" on this subject; some
"specialists" wrote about this:

- “Merlin wore many hats: he was a wizard or sorcerer, a prophet, a
bard, an adviser and a tutor,” (
http://claricemoran.wikispaces.com/Merlin )

...but some other authority prefers to see him as a wizard rather:
http://www.castles.me.uk/merlin-the-wizard.htm

- anyway, the other one described the difference:

"What makes a wizard different from an enchanter, a magician, a
sorcerer, a thaumaturgist, etc.? Well, sorcerers are sometimes evil,
`black magicians' (i.e., practitioners of black magic)... But in
general, not a lot, although fantasy authors and FRPGs might use the
names with narrower meanings. [..] Another example: `The difference
between a wizard and a sorcerer is comparable to that between, say, a
lion and a tiger, but wizards are acutely status-conscious, and to
them, it's more like the difference between a lion and a dead kitten.'
"
( http://galatea.meccahosting.com/~a0006753/wizards%20world.htm )

In conclusion: "wizard" writes extraordinary drivers - "sorcerer"
creates e.g. very interesting... viruses. ;)

Thanks, I think, that it could be worthy to add this comment to UIDE-s
readme.txt.
