I have an Athlon system with a VIA KT133A chipset.  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.

Thanks.
