Slightly less short:

The sonnet.library is a driver for the Sonnet 7200 G3/G4 PCI card.
What is needed:
- Amiga with Zorro III/PCI slots compatible with a Mediator.
- Elbox Mediator 3000Di/4000Di with 3.3V rail.
- 68040 or better.
- A Radeon 92xx or 3DFX Voodoo3/4/5 card.
- Mediator Warp3D 4.2 for 3D graphics in combination with a 3DFX Voodoo card.
- Sonnet 7200 PCI Card. Supported are MG3-400-512K; MG3-400-1M; MG3-500-1M; 
- 5V 168 pins FPM DIMMs (up to 256 MB in combination with the Voodoo3; 
  128MB with other supported video cards).
- pci.library version 11.0 or higher.
- AHI for sound. AHI 4.18 recommended.
What does it do:
The library interfaces between the CPU and the memory on a Sonnet 7200 G3/G4
PCI cardand the Amiga CPU and memory using the MPC107 chipset on th Sonnet
card. It also offers WarpOS/powerpc.library compatible functions.
What does this mean:
It essentially adds a second CPU to your Amiga through the PCI slot. 
This being either a 400 or 500 MHz G3 (MPC750) or 400 MHz G4 (MPC7400).
This CPU can be used to run (certain) WarpOS software.

The PPC CPU on the Sonnet card cannot DMA to Amiga memory. Any access to
non-Sonnet/PCI memory by the PPC is very slow. Patch programs are provided to
push code/data needed by the PPC CPU inside PCI/Sonnet memory. This is done on
two levels: on the binary level by patching hunk headers of WarpOS programs
and by changing references from powerpc.library to sonnet.library and on
system level by patching the memory allocation function AllocMem(). Both patch
programs can be obtained through the URL provided above. One of them is
included in this archive.

Not all functions of the powerpc.library are yet implemented or will be
implemented (for example memory protection). 100% compatibility will probbly be
never achieved, mostly due to hardware banging of certain WarpOS software.

Sound is restricted to AHI. Paula 8 bit DMA is the recommended setting. At this
moment, the SB128 and FM801 drivers produce a distortion in the sound output.
This is not a drop-in for the powerpc.library. The advantage of this is that
you now can have 2 PPCs in your system (the other one being a Cybersorm PPC
card). The drawback is that you need two different binaries for each library.
The original binary for WarpOS/powerpc.library and a patched binary for the
The driver/library is still being actively developed and is in an alpha stage.
The version number has been bumped to V17.0 (and now to 17.3) to supersede the
latest powerpc.library (V16.1) for patching reasons. Refer to for the latest build and the latest
documentation regarding compatibility, FAQs and issues. 

See for some demonstrations of
the Sonnet card in action.

In the archive:

sonnet.library:		The driver for the Sonnet 7200 G3/G4 PCI card.
InitSonnet: 		Initializes the Sonnet card.
GetInfo:		Simple program to show the state of the PPC CPU on the
			Sonnet card after initialization.

The Sonnet card can only be initialized after the graphics card has been
initialized. This means after C:LoadMonDrvs in the Startup-Sequemce. It is
however recommended to start the driver from the workbench using the provided

What has changed since 17.3:

- Fixed a few more potential hangs with well placed syncs.
- GetInfo() now recognizes modded 433/466/533 MHz Cards.
- Z flag of 68K interrupt now handled correctly upon exit interrupt.
- User code no longer addresses the zero page. That is now Supervisor only.
- Kernel and graphics memory are now handled by BATs by default.
- L2 cache can now cache instructions, not only data.
- L2 cache now set to 200MHz for 400/1MB version instead of 133MHz.
- Fixed a bug in GetHALInfo().
- Fixed a bug where inter-CPU messages were duplicated.
- Inter-CPU messages can now be up to ~64K in size instead of 150 bytes.
- Other miscelaneous fixes to increase stabilty and speed.

What has changed since 17.0:

- Moved all patches inside the library, no more different start-up programs.
- Fixed a bug in CreatePPCTask(). Now APDF works.
- Added better error handling through pop-up windows/requesters.
- Added a ramlib patch to increase stack when needed.
- Fixed the TagItem functions. Now more demos from Mad Wizards started working.
- Fixed a bug in GetInfo that was masked by the bug in the TagItem functions.
- Added shared signal system. Now the signals are shared by the 2 processors.
- Fixed LockTaskList function. Wrong result was returned.
- Added CPUUSage, Busy, Activity, CPU Load and System load code (for WarpStat).
- Fixed a bug in DeleteTaskPPC() as the Snoop list was not correctly freed.
- Fixed a bug in PutXMsg(). WES should work now (albeit slow).
- Added alignment support to AllocVecPPC(); For iFusion..No that does not work.
- Fixed a missing opcode in the FPU alignment emulation code. Now Q1A works.
- Other miscelaneous fixes and optimizations.

The future:

Improving the compatibility with WarpOS. Maybe a version for a towerized A1200.
Albeit that several attempts have utterly failed. Also, the patch tools are not
very user-friendly/flexible. This is on the To-Do list.
