## Execution Guidelines

1. **Use dmidecode extensively**: Primary source for board info
2. **Cross-reference with lspci**: Verify chipset and slots
3. **Check physical vs. logical**: Some slots share lanes
4. **Document slot usage**: What's installed where
5. **Identify chipset features**: What the board can do
6. **BIOS version importance**: Check for updates
7. **Expansion planning**: Available upgrade paths
8. **Power delivery assessment**: Adequacy for components
9. **I/O inventory**: Complete port count
10. **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.
