Hi,

I'm still having some problems with Sig 11's appearing randomly in FreeBSD
and I doubt that it is a bad hardware problem.

I have been looking at my BIOS settings.  The wait states are already maxed
out (3 read, 2 write).  As per the advice of another newsgroup reader, I
disabled the Hidden Refresh option which seemed to help.

There are several options in my BIOS that I do not know what they do.  My
BIOS is an AMI (American Megatrends) from 1993.  I have no documentation:

- Single ALE.  An enable/disable.   I don't even know what ALE stands for
- Fast decode.  Again, enable/disable.
- AT bus speed.  Has options like CLK/6 and CLK/5.
- Cache pattern.  Currently at 3-2-2-2.  I have no idea what this sets.

Any help would be greatly appreciated.

A note on Single ALE.  I tried enabling it (just as an experiment) and when
I did so, the performance degredation under text mode DOS alone was
noticeable when doing a DIR listing.  I actually first noticed this
performance hit when the system information box came up slower than usual.

Thanks again!
