Hello!

I have just installed a SunPCi III Pro in a SunFire V240. I have made a
fresh install of Windows XP on a 5GB virtual disk. I then installed
version 6.2 of Microsoft Messenger.

My problem is that the SunPCi card is resetting, and rebooting at will.
I have found a way to reproduce the problem. Just start Messenger 6.2
and press a key and keep it down so it key repeates. When two lines of
text is printed and the next character has to go to the third line it
crashes. If I change the size of the window it is the same - the char
after 2 lines of text crashes it.
It can also happend when closing Internet Explorer windows. But I cannot
find a way to reproduce this. It seems to happend on random.

This is my thoughts:

1. Enough power?
I only have one power supply but the coprocessor card is not that power
hungry (40W max). I have two CPUs but only one disk. No other PCI cards
(besides the SunPCi USB daughter board).

2. Microsoft software problem?
It is a fresh install of XP (service pack 2) and a fresh install of
Messenger. I have installed all updates from Microsoft.
My installation has not been poluted with anything else.
Norton antivirus has tested this system to be virus free.
I tried to redownload and reinstall Messenger 6.2. Same problem. I tried
version 7.0beta. It made the machine crash on startup and go into a
crash-reboot loop.

3. Solaris problem?
I am running Solaris 9 with all patches released on the 25. Jan 2005
applied.

4. SunPCi hardware problem.
I do not think it can be a memory problem on the SunPCi card. The card
has 1GB (2x512M) of memory. If it was a memory problem I think I would
get a blue screen from Windows and much more random crashes. The 3 line
problem in messenger happends EVERY time also after reboots. This makes
it unlikely that it is a memory problem.

5. SunPCi software problem?
I installed the latest release of the software (3.2.2) and applied patch
118591-1.
Could it be the SunPCi software that, for some reason, makes Windows
reset. I am not sure if this could be it or what about a SunPCi BIOS
problem? The version of the BIOS is 0.079
I have tried to downgrade to SunPCi 3.2.1 (which was the version
delivered with the coprocessor card). It did'nt solve the problem either.

Do any of you have any ideas what could cause this extreemly annoying
behaivour? Or any ideas on how to proceed. Should I just return the
board as defective?

Thanks in advance!
