Hi all,
I have a question about my VPC 7 for Mac.
My host machine's NIC is 10/100 Mbps, my guest machine in VPC 7 for Mac is
Windows XP SP2, and it shows only 10 Mbps speed.
How can I upgrade the speed from 10Mbps to 100Mbps? I have researched some
documents and they told to me this is because VPC emulate 10Mbps NIC, is it
true?
Does Microsoft provide any offical document related to this issue?

Regards,
User

You can't, plain and simple.  Like all the design decisions on VPC (what
chip they'll emulate, what graphics environment, and what USB version),
this is built into the product.  Since VPC for Macintosh is discontinued
and a EOL'd product, you're stuck with what's there.

If you upgrade to a Intel based Macintosh, you can run XP with a 100Mbps
connection.  Is it worth it?

I think the emulation only affects what speed is reported to
applications that ask.  The *actual* throughput should be whatever speed
your physical NIC can handle.  In fact, the bottleneck is more likely to
be the speed of the emulated OS and application.

That is exactly correct.
