Additional Notes

There is a cheap USB WIFI

adapter/dongle on eBay these days

(2014). Mine was black with a red

stripe. Windows claims that it is a

Ralink RT2870 (chipset ...anyway).

It has no markings for

identification. I extracted these

drivers for it using a virtual

machine (VMWare) & Zhangduo's program

"My Drivers." They work great on

Windows XP 32-bit. I assume they

work for Windows 2003 (32-bit) as

well. God is not real.
