Hi all, I'm now running XP Home with the following config: A7V-133 (VIA 4in1 4.37a installed, but i guess that doesn't matter as it's not properly installed as a news update pointed out in this site recently) GeForce2 MX400 (Latest driver installed) 512MB RAM 1.2GHz Althon SB Live Two IBM 40G 7200rpm harddisks I have set up RAID 0 using the onboard Promise controller. My problem is I get an error message on bootup saying the Promise Filter Driver I have is costing the system stability and is therefore disabled. I have no idea why it is the case, since I have got the latest driver from Promise's web site and installed in properly. Anyone has encountered the same problem? Solution? I have checked the Device Manager and find the driver is still working. It's really a mystery. I don't know if this has to do with the Bootvis problem I have. Bootvis gives me a disk error message on first trace. Again, anyone has the same experience? Occassionally, I may experience system locks up on bootup (the desktop appears then loading funnel keeps turning with nothing shows up in the system tray and the START button is not functioning, too). I will do a hard reset and everything is back in order. Anyone has any idea what's going on? Many many thanks to you all!!! I'm not going to get another mobo with VIA chipsets, that's for sure.
