>Description:
Reboot machine, using "shutdown -r" instruction cause damage CMOS. After
CPU restart I have a note, that "CMOS checksum failed, defaults loaded".
The Windows95, Ms-DOS and compaq Setup diskette are reboot computer normally,
without cause damage to CMOS. Then CMOS resets to defaults, setting for
date/time and peripherals stay good, but other such as: "Non-dos partition"
option set are loaded from defaults.

Machine: Compaq deskpro 466 model, i486-DX2 processor,
video: S3 trio64, embedded video is disabled in bios.
>How-To-Repeat:
after rebooting by instruction: shutdown -r now 
>Fix:
search, search, but can't find problem-solving...

State-Changed-When: Mon Mar 13 19:55:54 UTC 2006 
State-Changed-Why:  
So when you try a newer version (if that still runs on your 
rather old hardware) does that give the same results? 
4.11 for instance or 5.4,5.5-BETA3,6.0,6.1-BETA3 ? 

4.X is no longer being actively developed so we should 
check whether new releases still have this potential 
bug.  Also did you try some newer hardware with a 
recent version of FreeBSD? Did you check whether the 
battery that is inserted in the CMOS is still OK ?

State-Changed-When: Mon Mar 13 21:52:10 UTC 2006 
State-Changed-Why:  
Seems that pnp mode on the compaq might have been the 
issue.  Submitter removed a card and everything 
works fine.  No more hardware errors according 
to the submitter and he also mentions the PR can 
be closed.
