I was having occasional crashes when my PC-133 memory was set to 133MHz (stable at 100MHz). Søren Schmidt suggested turning off page-mode access in the BIOS setup. This has eliminated the problem (thus far) and I did not notice any degradation of performance. However, my wife has an identical system in terms of hardware but she is running Windows 98SE. I decided to turn off page-mode access on her machine but Windows slowed to a crawl. Turning page-mode access back on brought the machine back up to speed. I am curious why this would be. Apparently FreeBSD and Windows make use of the BIOS settings in different ways.
