Vista Upgrade Advisor Questions

I preparation for a clean install of Vista Home Premium from within my
WinXPSP2 PC, I ran the above and got 3 device querys as under. Any guidance?

1. AcerLAN ALN-201 PCI Ethernet Adaptor (yeah I KNOW it's old, but - til now
- it works!) "No Compatability Data"
2. Intel System Management Bios Driver "No Compatability data"
3. Patin Coufin (VSO) Software "no compatability data". This driver sits in
c:\windows\system32\pcoufin.sys

PowerDVD, Microsoft Intellipoint v5.5 (came with a brand new MS Wireless
Laser 5000 mouse I JUST bought!) and MSN Exporer and MSMessenger are listed
as software that might have minor compatability issues (3 MSoft programs!!!)
whereas other stuff I have like Roxio EasyCdCreator V5, DVD Shrink and
Audiograbber - all really OLD products that I DO use) are not listed as
'worrisome". CAN THAT be right??

I am running an XPPro SP2 2.8Celeron with 2.75g RAM.

Any thoughts?
