Okay, I have tried loading no drivers and then with just the packet driver running fdupdate. It still crashes. Is there a way to scan for bios usage of memory so that I can put in the necessary exceptions? The PCISLEEP comment is interesting, but I'm on an old EISA only Intel 80486 DX2-66 that uses 32 pin simms. The bios is an AMI bios circa 1993. I'll see about grabbing a copy of memteste. ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
