Complete original ForgeOS source archive

This is the authoritative original ForgeOS.zip, split at raw byte boundaries for Cloudflare delivery. It is not recompressed, trimmed, renamed internally, or replaced by the smaller Section 1 kit. Concatenating the five files in the exact order below recreates the original archive byte-for-byte.

Lifetime entitlement required. Every part, checksum file, manifest and reconstruction script below is protected as a Lifetime download. Course Access and Builder accounts cannot retrieve these files.

Authoritative identity:
Filename: ForgeOS.zip
Exact size: 99,756,830 bytes
SHA-256: 0b3756ef1f6362c04d42651843b26a4942d0d711a61c98b9dd6ea863edca10e1

Download all five parts

Save every part in the same directory. Browser renaming must be corrected before reconstruction; the filenames and order are exact.

Verification files and rebuilders

Download JSON manifest Download SHA-256 list PowerShell rebuilder Bash/Linux rebuilder

Windows PowerShell

Put the five parts and reconstruct-forgeos-source.ps1 in one directory.
Open PowerShell in that directory.
Run the commands below. The script verifies every part before writing anything, refuses to overwrite an existing archive, then verifies the reconstructed size and SHA-256.

Set-ExecutionPolicy -Scope Process Bypass
./reconstruct-forgeos-source.ps1 -PartsDirectory . -OutputFile ./ForgeOS.zip
Get-FileHash ./ForgeOS.zip -Algorithm SHA256

Linux, macOS or Bash

Put the five parts and reconstruct-forgeos-source.sh in one directory.
Open a terminal in that directory and run:

chmod +x ./reconstruct-forgeos-source.sh
./reconstruct-forgeos-source.sh . ./ForgeOS.zip
sha256sum ./ForgeOS.zip

On macOS without sha256sum, use shasum -a 256 ./ForgeOS.zip. The Bash rebuilder automatically supports either command.

Extract only after verification

The rebuilt archive is accepted only when it is exactly 99,756,830 bytes and hashes to 0b3756ef1f6362c04d42651843b26a4942d0d711a61c98b9dd6ea863edca10e1. Then extract ForgeOS.zip normally. The archive's original internal names and byte content have not been changed.

Different product: Section 1 bootable completion kit is the smaller, curated R32/DOOM build-and-boot package for Builder and Lifetime members. It is useful for the first course section, but it is not the complete original ForgeOS source archive.
