# hardware-report.ps1 - Report this machine's hardware to the PXE webapp so
# its Hardware Coverage page can flag models with no driver pack or BIOS.
#
# Called by check-bios.cmd, which every WinPE boot runs from the BIOS share
# before the imaging menu, so it reports every boot - including ones that
# never pick an image - rather than only those that reach the Y: status push.
#
# Sends the exact WMI model PESetup matches driver packs on, the Dell
# system SKU (what Dell's catalogs key on) and the BIOS version. Runs in
# WinPE's stripped PowerShell: wmic only, no CIM cmdlets. Best effort:
# logs to X:\Windows\Temp\hardware-report.log and never fails the boot.
