As Amiga OS4 for AmigaOne and CSPPC based machines nears completion, Hyperion is undertaking a survey to gauage demand for the BPPC version
Therefore if you are an Amiga1200 owner with a Dual Blizzard PPC card and would like to see OS4 ported to this machine, please send an email to: timdg@hyperion-entertainment.com
Please note: Ensuring that OS4 will work on the BPPC is a momumental task which will require enormous effort in both Time and Money. Therefore only email us if you have every intention of purchasing OS4 for BPPC.
Your support is very much appreciated in this matter.
Ben Hermans.

| Hyperion OS4 BPPC Survey : Comment 57 of 151 | ANN.lu |
| Posted by James Sellman on 03-Jun-2003 08:17 GMT | (What I'm posting here is just stuff that I have gathered from other sources. I'm not part of the OS4 kernel development team, nor am I a good enough coder to be able to be, so please take it with a grain of salt.)
As I understand it the BPPC's design is completely alien to the CSPPC, and it uses some software routines on the 68040/68060 for some things that are done with hardware logic on the CSPPC, for things like handling interrupts and such.
User space software works great on both cards because they both run userspace code near-identically. That's why all your WarpOS/PowerUp/etc. software works great on both...
But stuff that bangs the hardware (iFusion, and of course an OS including AmigaOS 4.0) doesn't work right on it unless written with support specifically for this stuff. IIRC (and I could be totally wrong) the card bootstraps initially loading PowerUp right away just to get things like interrupts working so the card functions at all -- and WarpOS still relies on this bit of code to work.
In any case I don't know for sure if this is a 100% accurate explanation of the problem (again this is just from second-hand stuff filtered through my frazzled memory at 4AM) but basically it will take a good deal of work to get OS4 working natively on the BPPC, time that could conceivably spent on improving the OS on the platforms it already works on instead. |
