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. + [http://204.200.238.31/cgi-bin/link.pl?co=i&cl=/ts/ibm/contact.html] + +---------------------------------------------------------------------------- + +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 edited] + + Edit Config .sys to have multiple config menus. I have one for win95, and + five for linux.

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 +c:\linux\boot\loadlin.exe @c:\linux\boot\parms\%CONFIG%.par + +:W95 +REM +REM Windows 95 stuff +REM +c:\toolkit\guard +SET MSINPUT=C:\MSINPUT +SET MWPATH=C:\MWW\DLL;C:\MWW\MWGAMES;C:\MWW\DSP +REM The following is used by DOS games to recognize Sound Blaster hardware. +REM If hardware settings are changed, please change this line as well. +REM See the Mwave README file for instructions. +SET BLASTER=A220 I5 D1 +SET MWROOT=C:\MWW +SET LIBPATH=C:\MWW\DLL +SET PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;E:\ORAWIN95\BIN;f:\msdev\bin;e:\v30\bin.dbg;v:\devt\v30\bin;c:\JavaSDK\Bin;C:\MWW\DLL; +SET INCLUDE=f:\MSDEV\INCLUDE;F:\MSDEV\MFC\INCLUDE +SET LIB=F:\MSDEV\LIB;F:\MSDEV\MFC\LIB +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 arguments 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 gotchas - You can either have CD sound OR Mixers but not both. That's 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. + +=========================================================== + _/ _/_/_/_/ + _/_/ _/_/ _/ + _/ _/_/ _/_/_/_/ Martin John Bartlett + _/ _/ _/ _/ (martin@nitram.demon.co.uk) +_/ _/_/_/_/ + _/ +_/ _/ + _/_/ +=========================================================== + + |
