when trying to install SP2 , i get this message, setup cannot copy the file atapi.sys,then underneath it says ensure that the location is correct or change it and insert windows xp system files in the drive yuo specify, copy files from c:\windows\system32\drivers.when i check device manager i have a! beside a non plug and play serial. the device status is not present or is not working properly or does not hsve all its drivers installed code 24, current statud stopped , star up type auto
Try running a System File Check before trying to load SP2. Start/Run/Type sfc /scannow (watch the space between sfc and /scannow) You will need your XP Disc. That will put all the system files back to original.
I have used the repair operating system to replace all the files but it still has the same problem. I had no problems installing sp2 the first time but after having to FULLY reinstall xp i now have this problem .
