Adding Newer Drivers to Windows XP

You would have to manually update an image on the new system with the drivers and then run sysprep on it.

Are all 120 different machines different models? If so, that is just insanity on a level I've not seen since the last Texas Chainsaw Massacre flick playing down at the local Drive-In!

Have you considered using SMS or some other application to assist you im managing those images?

I got started, but haven't had time to finish. Tons of info there.
good Luck.

ghost. what a PITA. the PITA to end all PITA's...
you are not using Home, right??
every wonder why Dell, HP, Compaq, other big boys do not use Ghost? they use custom installation scripts to reinstall XP. that's what i suggest for you also.
once you got the script, you can drop new windows updates and new drivers into the 'oem' folder where your script would go looking for them. see how at technet at support.microsoft.com. lots of microsoft wizards and free downloads to help you do this. crazy, yes. insane, no. get them to buy you the XP certification study books from microsoft. it will have good explanation of auto installing options. start hanging out at technet and support.microsoft.com

Look at the article at http://www.dell.com/downloads/global/solutions/SysPrepSingleImage_Legal_3.5.04_Final.doc
