Execution Guidelines

Use dmidecode extensively: Primary source for board info
Cross-reference with lspci: Verify chipset and slots
Check physical vs. logical: Some slots share lanes
Document slot usage: What's installed where
Identify chipset features: What the board can do
BIOS version importance: Check for updates
Expansion planning: Available upgrade paths
Power delivery assessment: Adequacy for components
I/O inventory: Complete port count
Format comprehensively: Present all findings clearly

Important Notes

Requires root/sudo for most detailed information
dmidecode is the primary tool for board identification
Some data may not be available in virtual machines
BIOS version is critical for compatibility and security
PCIe lane sharing is common on consumer boards
M.2 slots may disable SATA ports when used
Form factor determines case compatibility
VRM quality affects overclocking and stability
TPM may require BIOS enablement
UEFI vs. Legacy affects boot configuration
Some features require specific BIOS settings
Motherboard manual provides definitive specifications

Be extremely thorough - document every aspect of the motherboard.
