Hello djayakum,

Binding, it's the same. Info exposed, not. Generally, xp exposes more info than 2k, and 2k, 9x etc. (It's ever growing.) So, it depends on what you want to find out on the client machine.

djayakum,

As you said some m/c do not work, so I suppose you know how to get it. My these lines are just meant to verify with yours, in case ...

Win32_bios and win32_systembios classes have got early attention and supported by 9x up. But some lately developed properties are only supported by xp or 2k3 like .bioversion at the present realization. If you want to get bios' serial number, it is well supported from 9x up.

You may find it useful to check the detail with sdk.

set svc=getobject("winmgmts:root\cimv2")
set cBios=svc.execquery("select * from win32_bios")
for each oBios in cBios
    sSerialNumber=oBios.serialnumber
    exit for
next
set cBios=nothing
set svc=nothing
'sSerialNumber is the number in string you want to get

But, of course you know, for win9x & winnt, you need to install specifically the wbemcore component. And, that may be the reason of your posting?
