No difference. This is probably because both drivers are fake.
I presume the SCSI driver is there to accommodate folks that
have code that makes SCSI calls.

Speaking of fake, it took me years to bend my mind around the fact
that the VM CPUs are fake too.  They are not actually using
a particular CPU.  It was a light bulb moment.

Oh ya.  The latest batch of notebooks are a nightmare to install
XP on.  It is made a lot easier if you only do it on models
with Intel chipsets.  (Did an AMD XP upgrade from Vista on an
HP laptop a couple of years ago.  Took me 15 hours.  Gad zukes!
I could only bill for 3 hours.  Never again -- nightmare stuff.
On the bright side, it is now the customer's fastest, most
reliable computer -- it was completely unusable under Vista.)

Here is a tip: call Lenovo tech support and find a model that
still has a set of XP restore disks.  That is the easiest
way.

On my VM, W7 is still half as fast as XP and ten times less
stable -- pretty much matches what I see in the field.
And Lotus Approach, which I use for my business accounting,
runs worse on W7 than it runs on Wine.

Except that it slows the backups down by a factor of five.

Ultimately, on a server, it would probably be Windows 2003
server that I would put in a VM.  (They make great Terminal
Servers; Windows Server 2008 is an absolute nightmare to
run Terminal Services through: five times slower, crash all the
time, ...)  So, I would need to find it WS2003 did the same
backup slowdown, but I can not afford the license to
find out.  Suppose I will solve that when the need arises.
