• Detailed hardware upgrade steps including chassis extension, component removal (covers, CD-ROM, option modules, old backplane), new backplane and cable installation, and reassembly.
• Updating system firmware using various methods and LFU commands.
• Updating EISA configuration data.
• Restoring custom system configurations after the upgrade.

The guide emphasizes safety warnings, required tools, and specific commands for the update procedures.
