My MicroA1 motherboard arrived from the dealer bundled with Amiga OS 4.0 Developer Pre-release on a CD-R disc. My official CD arrived a few months later. All other updates came as downloads, including Amiga OS 4.0 The Final Update (December 24, 2006) and Amiga OS 4.0 July 2007 Update. I burned these ISO files onto CD-R discs.
