It is 10.3 dated 10/15/2001

The system detected an internal processing error at
location ##0168:fff0f667 - 000f:e667
60000, 9084

0886090f
Internal revision 14.103a_SMP

I thought that is what this indicated.

How do you obtain this info?

This machine has been running fine for a year and a half, which is why I 
thougnt I may have a hardware problem.  I was going to say that i 
changed nothing but about a month ago I was trying to get a Brother MFC 
printer to work.  I tried it both as a network printer and as a usb 
printer, but was unable to get it to work.  As part of trying to get it 
to work as a network printer I have been loading LPRPORTD.  I don't know 
if this qualifies as changing something that may effect a scsi driver.

OK scratch that idea.

Not guilty on that count.  I have used Windows so little that I don't 
know enough about it to have it influence my thoughts on computer 
problem solving.
