We need to change the BIOS settings on approx 2500 machines, to set
PXE as the primary boot device. Before visiting every desktop, I would
like to use WMI to query this info, but I can't find how to query data
from the BIOS itself. Any sugegstions? Thanks.

Hello,
you have to query your PCs with WQL language, like  "SELECT * FROM
WIN32_BIOS"
you can find information about how to query WMI with WQL at this url:

Thanks for the suggestion. I am able to pull whatever BIOS information
Windows has access to using WMI, ie:

Win32_BIOS(1).BiosCharacteristics=[7;9;10;11;12;15;16;19;20;21;22;23;24;25;26;27;28;29;30;32;33;34;36;37;40;41]
Win32_BIOS(1).BIOSVersion=[INTEL  - 20040421;BIOS Date: 04/21/04

Win32_BIOS(1).Caption=BIOS Date: 04/21/04 15:58:22 Ver: 08.00.10

Win32_BIOS(1).Status=OK
Win32_BIOS(1).TargetOperatingSystem=0
Win32_BIOS(1).Version=INTEL  - 20040421

However this information does not include boot device priority.
Perhaps I am confusing BIOS with CMOS??
