Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

1 | How to try to survive an IBM Mwave under Linux SB drivers | ||
2 | |||
3 | |||
4 | + IBM have now released documentation of sorts and Torsten is busy | ||
5 | trying to make the Mwave work. This is not however a trivial task. | ||
6 | |||
7 | ---------------------------------------------------------------------------- | ||
8 | |||
9 | OK, first thing - the IRQ problem IS a problem, whether the test is bypassed or | ||
10 | not. It is NOT a Linux problem, but an MWAVE problem that is fixed with the | ||
11 | latest MWAVE patches. So, in other words, don't bypass the test for MWAVES! | ||
12 | |||
13 | I have Windows 95 on /dev/hda1, swap on /dev/hda2, and Red Hat 5 on /dev/hda3. | ||
14 | |||
15 | The steps, then: | ||
16 | |||
17 | Boot to Linux. | ||
18 | Mount Windows 95 file system (assume mount point = /dos95). | ||
19 | mkdir /dos95/linux | ||
20 | mkdir /dos95/linux/boot | ||
21 | mkdir /dos95/linux/boot/parms | ||
22 | |||
23 | Copy the kernel, any initrd image, and loadlin to /dos95/linux/boot/. | ||
24 | |||
25 | Reboot to Windows 95. | ||
26 | |||
27 | Edit C:/msdos.sys and add or change the following: | ||
28 | |||
29 | Logo=0 | ||
30 | BootGUI=0 | ||
31 | |||
32 | Note that msdos.sys is a text file but it needs to be made 'unhidden', | ||
33 | readable and writable before it can be edited. This can be done with | ||
34 | DOS' "attrib" command. | ||
35 | |||
36 | Edit config.sys to have multiple config menus. I have one for windows 95 and | ||
37 | five for Linux, like this: | ||
38 | ------------ | ||
39 | [menu] | ||
40 | menuitem=W95, Windows 95 | ||
41 | menuitem=LINTP, Linux - ThinkPad | ||
42 | menuitem=LINTP3, Linux - ThinkPad Console | ||
43 | menuitem=LINDOC, Linux - Docked | ||
44 | menuitem=LINDOC3, Linux - Docked Console | ||
45 | menuitem=LIN1, Linux - Single User Mode | ||
46 | REM menudefault=W95,10 | ||
47 | |||
48 | [W95] | ||
49 | |||
50 | [LINTP] | ||
51 | |||
52 | [LINDOC] | ||
53 | |||
54 | [LINTP3] | ||
55 | |||
56 | [LINDOC3] | ||
57 | |||
58 | [LIN1] | ||
59 | |||
60 | [COMMON] | ||
61 | FILES=30 | ||
62 | REM Please read README.TXT in C:\MWW subdirectory before changing the DOS= statement. | ||
63 | DOS=HIGH,UMB | ||
64 | DEVICE=C:\MWW\MANAGER\MWD50430.EXE | ||
65 | SHELL=c:\command.com /e:2048 | ||
66 | ------------------- | ||
67 | |||
68 | The important things are the SHELL and DEVICE statements. | ||
69 | |||
70 | Then change autoexec.bat. Basically everything in there originally should be | ||
71 | done ONLY when Windows 95 is booted. Then you add new things specifically | ||
72 | for Linux. Mine is as follows | ||
73 | |||
74 | --------------- | ||
75 | @ECHO OFF | ||
76 | if "%CONFIG%" == "W95" goto W95 | ||
77 | |||
78 | REM | ||
79 | REM Linux stuff | ||
80 | REM | ||

85 | SET PATH=C:\WINDOWS;C:\MWW\DLL; | ||
86 | CALL MWAVE START NOSHOW | ||

105 | win | ||
106 | |||
107 | ------------------------ | ||
108 | |||
109 | Now build a file in c:\linux\boot\parms for each Linux config that you have. | ||
110 | |||
111 | For example, my LINDOC3 config is for a docked Thinkpad at runlevel 3 with no | ||
112 | initrd image, and has a parameter file named LINDOC3.PAR in c:\linux\boot\parms: | ||
113 | |||
114 | ----------------------- | ||
115 | # LOADLIN @param_file image=other_image root=/dev/other | ||
116 | # | ||
117 | # Linux Console in docking station | ||
118 | # | ||
119 | c:\linux\boot\zImage.krn # First value must be filename of Linux kernel. | ||
120 | root=/dev/hda3 # device which gets mounted as root FS | ||
121 | ro # Other kernel arguments go here. | ||
122 | apm=off | ||
123 | doc=yes | ||
124 | 3 | ||
125 | ----------------------- | ||
126 | |||
127 | The doc=yes parameter is an environment variable used by my init scripts, not | ||
128 | a kernel argument. | ||
129 | |||
130 | However, the apm=off parameter IS a kernel argument! APM, at least in my setup, | ||
131 | causes the kernel to crash when loaded via loadlin (but NOT when loaded via | ||
132 | LILO). The APM stuff COULD be forced out of the kernel via the kernel compile | ||
133 | options. Instead, I got an unofficial patch to the APM drivers that allows them | ||
134 | to be dynamically deactivated via kernel arguments. Whatever you chose to | ||
135 | document, APM, it seems, MUST be off for setups like mine. | ||
136 | |||
137 | Now make sure C:\MWW\MWCONFIG.REF looks like this: | ||
138 | |||
139 | ---------------------- | ||
140 | [NativeDOS] | ||
141 | Default=SB1.5 | ||
142 | SBInputSource=CD | ||
143 | SYNTH=FM | ||
144 | QSound=OFF | ||
145 | Reverb=OFF | ||
146 | Chorus=OFF | ||
147 | ReverbDepth=5 | ||
148 | ChorusDepth=5 | ||
149 | SBInputVolume=5 | ||
150 | SBMainVolume=10 | ||
151 | SBWaveVolume=10 | ||
152 | SBSynthVolume=10 | ||
153 | WaveTableVolume=10 | ||
154 | AudioPowerDriver=ON | ||
155 | |||
156 | [FastCFG] | ||
157 | Show=No | ||
158 | HideOption=Off | ||
159 | ----------------------------- | ||
160 | |||
161 | OR the Default= line COULD be | ||
162 | |||
163 | Default=SBPRO | ||
164 | |||
165 | Reboot to Windows 95 and choose Linux. When booted, use sndconfig to configure | ||
166 | the sound modules and voilą - ThinkPad sound with Linux. | ||
167 | |||
168 | Now the gotchas - you can either have CD sound OR Mixers but not both. That's a | ||
169 | problem with the SB1.5 (CD sound) or SBPRO (Mixers) settings. No one knows why | ||
170 | this is! | ||
171 | |||
172 | For some reason MPEG3 files, when played through mpg123, sound like they | ||
173 | are playing at 1/8th speed - not very useful! If you have ANY insight | ||
174 | on why this second thing might be happening, I would be grateful. | ||
