-            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.
