Can someone tell me what was included inside the red box that came with the ps2 linux kit. I think it might be the Ps2 hard disc drive, but i'm not sure.
That's the "gaming" HDD kit. There's a customized SONY HDD (it has custom DRM functions embedded on the drive firmware) a utility disc to format it on the format games use and the documentation. Edit: The hdd looks like this: You see, it's just a 40GB Seagate U5 series drive with custom firmware and no rubber jacket.
Strange. mine shipped in brown matte boxes, not shiny coloured ones. It was the last batch though, within a few months they didn't have complete sets.
There's a IBM Deskstar type too but it's kind of rare ... lol (Maxtor Diamond Max D540X mounted in a external enclosure for PCMCIA network adapter)
I've seen NTSC J ones in brown carb boxes, the red one above for Linux, and I have two PAL labeled white ones that contain the HDD, documentation, but no disc. SCPH-20401EL. It looks like some versions ship with the Network Adapter included, and some not. The top picture is clearly the Linux package, and as l_oliveira says the smaller one is the Game Kit HDD. Edit: I think the brown NTSC J one I saw was a PCMCIA HDD kit!
There were a lot of different packages. SONY changed their minds at some point and renamed the HDD kit (Network Adapter + HDD + disc + documentation) as "BB Unit" at some point when they introduced the PlayStation Broad Band Navigator (PSBBN). The red box was the original kit with the Utility disc 1.00 (standard OSD). And at that time only the Japanese version existed so obviously only Japanese Linux kits would come with the said disc.
