Thanks StarRiver, for your tests. I'm afraid I'm stuck with the 512MB card. I bought it at a store where I went for the first time and it was the only AGP card they had. I mentioned that I added an extra 1GB to my PC and had maxphyspage set to 512MB. Well my Win98 install started to act up, the swap file couldn't be on another drive, Norton Windoctor couldn't access system.dat and startups that hung. I looked at some of the other threads here and then d/l-ed himemx and tried with that and everything went back to normal... Anyway, I'll try to get my Win98 through some virtual machine software. I really only need it for my printer, an HP710C, which has only the most basic support in XP with their 'standard driver'... And I occasionally play some old games, some of which use 3DFX's Voodoo 2. Yep, I still got one of those in my system too. DDP
