I have reinstalled WXP home on my medium aged Dimension 4550 using the original DELL reistallation disk (with SP1) slipstreamed with SP2. All fine, but I am experiencing a problem with the antivirus Mcafee Enterprise 8.0.0 (the same that was running since a lot of time on the same computer before the new installation of WXP): the installation went OK, but the on-access scan goes sistematically disabled after two or three second the computer is switched on. This happens only if I udpdate the virus definition on line or runnning  the appropriate sdat.exe downloaded from Mcafee site. I tried also to re-install the very original disk with SP1 only (and without installing the SP2 update) but again no success. This seems to be the only problem for now of this installation.

The only other small concern: is correct that the the second hard physical disk (with partition D) run in ULTRA DMA mode 2 and the first one in ULTRA DMA mode 5 ? I honestly  don't remember the situation before.

I made a clean installation , reformatting also C partition  and all external devices disconnected (excluding monitor, keyboard and mouse).

I don't really what to do to fix these problem and I don' riosk to connect to Internet with thi at computer.

Last question: is there any need to activate the operating system or not? I have used the original DELL reinstallation disk.

 

Can anybody be of help?

Thanks and regards
