GNU/Linux came to the rescue.

wifiLinux saved my day. Yet another encounter with itchy scenario which I wished Ginnie could have completed and I could devote my time to bit more constructive work.
One of the typical answer that one gets when dealing with  msoft os is any problem is plainly/blindly blamed on virus. In the current senario it was the corrupt driver or inappropriate driver that was giving the problem BSOD.

The wifi wasn't working properly and wasn't sure whether it was the driver or the device itself(atheros -AR242x 802.11abg Wireless PCI Express Adapter )
so the linux(ubuntu) was used with the atheros driver to check the functionality of the device. the instruction(http://nothingcanstopu.blogspot.com/2009/06/ubuntu-804-atheros-communications-inc.html) previously scribbled came in handy and worked like a charm. no probs whatsoever.

The installation of OS using pen drive is almost becoming a defacto standard with the arrival of netbook which doesn't have an internal cd/DVD drive. there are almost Mton of article on how to make the usb stick bootable  -
for vista too one can make usb bootalbe with novicorp - wintoflash

With freebsd the installation is much simpler than linux as we just need to create a slice which latter on is partitioned. The GUI is as effective as any linux version. wasn't able to get the atheros wifi working even though the inbuilt option of atheros driver was present.
