+            Information about PowerPC Sound support
+=====================================================================
+
+Please mail me (Cort Dougan, cort@fsmlabs.com) if you have questions,
+comments or corrections.
+
+Last Change: 6.16.99
+
+This just covers sound on the PReP and CHRP systems for now and later
+will contain information on the PowerMac's.
+
+Sound on PReP has been tested and is working with the PowerStack and IBM
+Power Series onboard sound systems which are based on the cs4231(2) chip.
+The sound options when doing the make config are a bit different from
+the default, though.
+
+The I/O base, irq and dma lines that you enter during the make config
+are ignored and are set when booting according to the machine type.
+This is so that one binary can be used for Motorola and IBM machines
+which use different values and isn't allowed by the driver, so things
+are hacked together in such a way as to allow this information to be
+set automatically on boot.
+
+1. Motorola PowerStack PReP machines
+
+  Enable support for "Crystal CS4232 based (PnP) cards" and for the
+  Microsoft Sound System.  The MSS isn't used, but some of the routines
+  that the CS4232 driver uses are in it.
+
+  Although the options you set are ignored and determined automatically
+  on boot these are included for information only:
+
+  (830) CS4232 audio I/O base 530, 604, E80 or F40
+  (10) CS4232 audio IRQ 5, 7, 9, 11, 12 or 15
+  (6) CS4232 audio DMA 0, 1 or 3
+  (7) CS4232 second (duplex) DMA 0, 1 or 3
+
+  This will allow simultaneous record and playback, as 2 different dma
+  channels are used.
+
+  The sound will be all left channel and very low volume since the
+  auxiliary input isn't muted by default.  I had the changes necessary
+  for this in the kernel but the sound driver maintainer didn't want
+  to include them since it wasn't common in other machines.  To fix this
+  you need to mute it using a mixer utility of some sort (if you find one
+  please let me know) or by patching the driver yourself and recompiling.
+
+  There is a problem on the PowerStack 2's (PowerStack Pro's) using a
+  different irq/drq than the kernel expects.  Unfortunately, I don't know
+  which irq/drq it is so if anyone knows please email me.
+
+  Midi is not supported since the cs4232 driver doesn't support midi yet.
+
+2. IBM PowerPersonal PReP machines
+
+  I've only tested sound on the Power Personal Series of IBM workstations
+  so if you try it on others please let me know the result.  I'm especially
+  interested in the 43p's sound system, which I know nothing about.
+
+  Enable support for "Crystal CS4232 based (PnP) cards" and for the
+  Microsoft Sound System.  The MSS isn't used, but some of the routines
+  that the CS4232 driver uses are in it.
+
+  Although the options you set are ignored and determined automatically
+  on boot these are included for information only:
+
+  (530) CS4232 audio I/O base 530, 604, E80 or F40
+  (5) CS4232 audio IRQ 5, 7, 9, 11, 12 or 15
+  (1) CS4232 audio DMA 0, 1 or 3
+  (7) CS4232 second (duplex) DMA 0, 1 or 3
+  (330) CS4232 MIDI I/O base 330, 370, 3B0 or 3F0
+  (9) CS4232 MIDI IRQ 5, 7, 9, 11, 12 or 15
+
+  This setup does _NOT_ allow for recording yet.
+
+  Midi is not supported since the cs4232 driver doesn't support midi yet.
+
+2. IBM CHRP
+
+  I have only tested this on the 43P-150.  Build the kernel with the cs4232
+  set as a module and load the module with irq=9 dma=1 dma2=2 io=0x550

+          Information about the Linux/PPC kernel images
+=====================================================================
+
+Please mail me (Cort Dougan, cort@fsmlabs.com) if you have questions,
+comments or corrections.
+
+This document is meant to answer several questions I've had about how
+the PReP system boots and how Linux/PPC interacts with that mechanism.
+It would be nice if we could have information on how other architectures
+boot here as well.  If you have anything to contribute, please
+let me know.
+
+
+1. PReP boot file
+
+  This is the file necessary to boot PReP systems from floppy or
+  hard drive.  The firmware reads the PReP partition table entry
+  and will load the image accordingly.
+
+  To boot the zImage, copy it onto a floppy with dd if=zImage of=/dev/fd0h1440
+  or onto a PReP hard drive partition with dd if=zImage of=/dev/sda4
+  assuming you've created a PReP partition (type 0x41) with fdisk on
+  /dev/sda4.
+
+  The layout of the image format is:
+
+  0x0     +------------+
+          |            | PReP partition table entry
+          |            |
+  0x400   +------------+
+          |            | Bootstrap program code + data
+          |            |
+          |            |
+          +------------+
+          |            | compressed kernel, elf header removed
+          +------------+
+          |            | initrd (if loaded)
+          +------------+
+          |            | Elf section table for bootstrap program
+          +------------+
+
+
+2. MBX boot file
+
+  The MBX boards can load an elf image, and relocate it to the
+  proper location in memory - it copies the image to the location it was
+  linked at.
