Not that I am aware of. You can use the 'set' command above to see what
your clients return though.

These are some I found in a very quick google:

Microsoft -;en-us;266675
MSFT 5.0 - Windows 2000 and XP
MSFT 98 - Windows 98 and ME

PXEClient - system booting using PXE

and these werew from my simple tests:

Fedora Core 2 - not set
Solaris - SUNW.model where model varies with each model
