Fixed issue when I transferred drivers to a CD. Since my flash drive is using FAT32 it seems like all of the drivers and BIOS were changed to MS DOS applications. This is very starnge since I have existing applications on the flash drive. I also had to use another video card to install the XP SP2 from the DELL CD. I then used the driver to install the video for the onboard (integrated) video. 
I cannot upgrade the BIOS or install XP drivers on a DELL DIMENSION 2450 desktop 1. performed clean install several times using DELL system CD with SP2 2. disabled onboard video card and added another card to pci slot 3. re-downloaded DELL drivers 4. no errors after or while installing XP on system When I try to upgrade BIOS or install any driver, I get a pop window with 2 DOS windows that open and close quickly I also tried SAFE MODE and get the same result ANY SUGGESTIONS??    
XP Home drivers and BIOS upgrade
