+	How to try and survive an IBM Mwave under Linux SB drivers
+
+
+* IBM refuse to provide documentation. If anyone can ever find out what
+  MWD50430.EXE actually does to load firmware then this comedy could go
+  away.
+
+* If you'd like to ask IBM why they don't release Mwave information.
+  phone IBM (425-556-8822) and ask them why they still haven't 
+  released any documentation.

+----------------------------------------------------------------------------
+
+OK, First thing - the IRQ problem IS a problem, whether the test is bypassed or
+not. And it is NOT a linux problem - it is an MWAVE problem that is fixed with
+the latest MWAVE patches. So, in other words, DON'T bypass the test for MWAVES!!
+
+My config is Win 95 on HDA1, swap on HDA2, RH 5 on HDA3.
+
+The steps, then:
+
+    Boot to Linux. 
+    Mount Win95 file system (assume mount mount = /dos95)
+    mkdir /dos95/linux
+    mkdir /dos95/linux/boot
+    mkdir /dos95/linux/boot/parms
+
+    Copy the kernel, any initrd image, and loadlin to /dos95/linux/boot
+
+    Reboot to win 95
+
+    Edit C:/msdos.sys and add/change the following:
+
+        Logo=0
+        BootGUI=0
+
+        [Note msdos.sys IS a text file but it needs to be 'unhidden' and make
+         read-writable before it can be eddited]
+
+    Edit Config .sys to have multiple config menus. I have one for win95, and
+    five for linux. Like this:
+------------
+[menu]
+menuitem=W95, Windows 95
+menuitem=LINTP, Linux - ThinkPad
+menuitem=LINTP3, Linux - ThinkPad Console
+menuitem=LINDOC, Linux - Docked
+menuitem=LINDOC3, Linux - Docked Console
+menuitem=LIN1, Linux - Single User Mode
+REM menudefault=W95,10
+
+[W95]
+
+[LINTP]
+
+[LINDOC]
+
+[LINTP3]
+
+[LINDOC3]
+
+[LIN1]
+
+[COMMON]
+FILES=30
+REM Please read README.TXT in C:\MWW subdirectory before changing the DOS= statement.
+DOS=HIGH,UMB
+DEVICE=C:\MWW\MANAGER\MWD50430.EXE
+SHELL=c:\command.com /e:2048
+-------------------
+
+The important things are the SHELL and DEVICE statements
+
+    Then change Autoexec.bat. Basically everything in there originally should be
+    done ONLY when Win95 is booted. Then you add new things specifically for
+    Linux.  Mine is as follows
+
+---------------
+@ECHO OFF
+if "%CONFIG%" == "W95" goto W95
+
+REM
+REM Linux stuff
+REM
+SET MWPATH=C:\MWW\DLL;C:\MWW\MWGAMES;C:\MWW\DSP
+SET BLASTER=A220 I5 D1
+SET MWROOT=C:\MWW
+SET LIBPATH=C:\MWW\DLL
+SET PATH=C:\WINDOWS;C:\MWW\DLL;
+CALL MWAVE START NOSHOW

+win
+
+------------------------
+
+Now build a file in c:\linux\boot\parms for each linux config that you have.
+
+For example, my LINDOC3 config is for a docked Thinkpad at runlevel 3 with no
+initrd image, and has a parm file named LINDOC3.PAR in c:\linux\boot\parms:
+
+-----------------------
+#   LOADLIN @param_file image=other_image root=/dev/other
+#
+#	Linux Console in docking station
+#
+c:\linux\boot\zImage.krn         # first value must be the filename of the Linux-kernel
+root=/dev/hda3                    # the device which gets mounted as root FS
+ro                                      # Other kernel agruments go here
+apm=off
+doc=yes
+3
+-----------------------
+
+the doc=yes parm is an environment variable that my init scripts use, it is not
+a kernel argument.
+
+However, the apm=off parm IS a kernel argument!!!!!!! APM, at least in my setup,
+causes the kernel to crash when loaded via loadlin (but NOT when loaded via
+LILO). The APM stuff COULD be forced out of the kernel via the kernel compile
+options. BUT I, instead, got hold of an unofficial patch to the APM drivers that
+allows them to be dynamically deactivated via kernel arguments. Whatever you
+chose to document, APM, it seems, MUST be off for setups like mine.
+
+Now check the C:\MWW\MWCONFIG.REF looks like this:
+
+----------------------
+[NativeDOS]
+Default=SB1.5
+SBInputSource=CD
+SYNTH=FM
+QSound=OFF
+Reverb=OFF
+Chorus=OFF
+ReverbDepth=5
+ChorusDepth=5
+SBInputVolume=5
+SBMainVolume=10
+SBWaveVolume=10
+SBSynthVolume=10
+WaveTableVolume=10
+AudioPowerDriver=ON
+
+[FastCFG]
+Show=No
+HideOption=Off
+-----------------------------
+
+OR the Default= line COULD be
+
+Default=SBPRO
+
+Reboot to Win95 and choose Linux. When booted, use sndconfig to configure the  
+sound modules and VOILA - ThinkPad sound with Linux.
+
+Now the gottchas - You can either have CD sound OR Mixers but not both. Thats a
+problem with the SB1.5(CD sound) or SBPRO(Mixers) settings. No-one knows why
+this is!
+
+And, for some reason MPEG3 files, when played through mpg123, sound like they
+are playing at 1/8th speed - not very useful!!!!!!!!!!!! If you have ANY insight
+on why this second thing might be happening I would be grateful.
