Kurt, Turning on hardware virtualization is used for virtual pc performance and security. You can run without the hardware virtualization support, but the performance of the virtual computer will be slower. I've used USB-to-Serial on XP machines, but not Windows 7. If you buy a cable, make sure you get 2 because one of them is likely not going to work. Best Buy on 21st South sells them for about $37, but I'm sure you can find them cheaper online.

I'll give the Windows XP emulator more thought. Before posting, I stopped at the point when Windows Prof directed me to go into the BIOS settings to enable a Virtual PC. I felt that was getting too much into a "temporary hack" solution for a updated driver for one device, since my LPI is the only piece of gear or software that I need to install it for. Secondly, as Don noted, the Windows XP VM is glitchy, as I found in several newsgroup posts. But I'll take a second look at enabling a virtual Windows XP. I may decide to sit back and see if a light-weight, inexpensive low-res LPI camera that is Windows 7 compatible comes on the market. Thanks again for all the extended replies on this thread. - Kurt P.S. Come to think of it, I'll probably have the same problem on the outbound communication - that is a USB-to-Serial Converter that I would need to autoguide the scope. Anyone using a USB-Serial Converter that runs and installed under Windows 7 Prof? _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com
