You must read the message regarding software licenses in the Section called Third Party Software Licensing and Temporary Files in Chapter 1 before you install Windows 95 as a guest OS in Bochs.

Subject: [Bochs-developers] WinMe install tips
Parts/Attachments:
1) Install Win98
My Windows Me is an update version, that is, it upgrades over Win98.
So the first think I have to do is to install on a HD image a
Win98
It is not necessary to do the full install. What I've done is
- Create a HD image (Win98.img) with 500MB
- Format It, install MSDOS6 on it so I can boot from c
- Make a W98 directory.
- Copy using mtools the instalation directory from the original
Win98 CD
- Run bochs
- run the setup program into the W98 directory
- Select WIN98 as Windows directory. All other setup options
are left by default.
- I don't care about HW detection, etc. Just uncompressing
the cab files to the WIN98 directory es enought for WinMe.
(Note that Win98 is not functional and cannot boot)
2) Copy the WinMe install files to the HD
In Win98.img, with mtools, I create a directory called WinMe.
Again, I copy the contents of the Win9x directory from the original
WinMe CD. Note that I copy the CD to my HD, and then with mtools
from my HD to win98.img. I also delete then W98 directory.
3) Create WinMe.img
Now, I created another blank HD called WinMe.img with 500MB.
I format it and install MSDOS6 so I an boot using it.
4) Prepare the instalation Bochs
I edit the bochsrc.txt file so
- WinMe.img is diskc
- Win98.img is diskd
5) Running setup
I start bochs: the C: drive is empty (it only contains the
MSDOS6 command.com, IO.SYS, etc). The D: drive has:
D:\W98 - The "installed" Windows 98
D:\WINME - Windows Me setup files
I go to the WINME directory and run:
SETUP xxxx
The description of the setup options can be found in the Microsoft Knowledge page as
Q186111 - Description of the Windows 95, Windows 98, and Windows Me Setup Switches
I've done a lot of trials with this setup options until I finally
found a correct way to finnish the installation. These are the setup
options I used. I've copied a brief description (from the KB) and added
my comments.
/m - bypass the playing of the Setup sound (.wav) files.
Not necessary as my Bochs has no sound device activated
/nf - Do not prompt to remove the floppy disk from the drive
Maybe not necessary. Just in case
/nh - This switch bypasses running the Hwinfo.exe program at 0
percent files and RunOnce.
If not present, freezes on HW detection
/ie - This switch bypasses the Windows 98 Startup Disk wizard screens.
To speed things up - I allways can create a Statup disk latter
/iv - This switch bypasses displaying the Setup screens during
an upgrade within Windows.
To speed things up
/c - This switch bypasses running SMARTDrive.
Maybe not necessary. Just in case
/im - Causes setup to ignore the conventional memory check.
Maybe not necessary. Just in case
/is - This switch causes Setup not to run ScanDisk.
Very important as SCANDISK freezed bochs
/iq - If you use the /is switch to bypass ScanDisk or if ScanDisk
does not complete successfully, Setup checks your drive for cross-linked files.
The /iq switch prevents Setup from doing this.
Very important. If not used, Setup stop the installation
with a message "error found in C:, run scandisk and setup again"
(or something like this). Of course, there is no errors in C:
because is an empty, just formatted disk, but the WinMe setup
thinks so. The only way to progress from this point is
with this switch
/it - This switch bypasses checking for the presence of "dirty" or "deadly"
terminate-and-stay-resident programs (TSRs) that are known to
cause problems with Windows Setup.
Maybe not necessary. Just in case
/p b;g=3
b: This switch enables Prompt Before mode. It prompts
you before a detection module is called so that you can
step through each detection module manually and decide
if you want to skip it.
Very important. See bellow
g: This switch controls how verbose the built-in progress bar is
There is another main issue that must be handled
WinMe requires a 150Mhz computer as a minimum. If you try to run
the WinMe setup, you will receive a message telling you so, and the
installation will stop.
The only way I found to solve this problem is to change the IPS
value in bochsrc.txt. I raised the IPS value until setup stop
complaining. In my machine (P3 @ 450MHz), I achieved this with
ips: 500000000
This this IPS value, the keyboard and mouse are updated each
100 seconds. This makes very dificult to type the CD-KEY numbers,
select type of instalation, etc.
One way to solve this is to lower the vga_update_interval and
the keyboard_serial_delay. I lower the value until
- I have a minimum respons from keyboard and mouse (say
1 second delay between keypress/mousemove and the
screen update)
- I still pass the 150 Mhz check
The values I used are
vga_update_interval: 10000
keyboard_serial_delay: 200
They may be diferent for other computers.
Note that bochs, on starting up complains about vga_update_interval
with the message "bochsrc.txt: vga_update_interval not big enough!":
ignore it.
6) Follow the Windows Me setup instruction ...
Just a warning: it is very, very, very, *VERY* (very) slow ...
Two days running non stop on my PC.
Don't wait ... enjoy yourself during the process ... you that the time.
7) Hardware nightmare
At a given moment, you are prompted to detect the hardware.
There is a prompt for each type of device: Bus, keyboard, mouse,
HD, CDROM, etc.
Say NO to everything.
If you say YES, sometimes setup will detect your HW, but normaly
it will crash with GPF on COMMCTRL.DLL (setup crash, but bochs
still alive. Nice!).
If you sat CANCEL, setup will stay in this screen forever (ok, ok,
I have just wait 10 hours).
8) Configuring
Setup will configure you PC. You can set your timezone, etc.
Then Setup will create the Statup menu icons. Here, time to time,
you will get a GPF in PIFMGR.DLL. Just press Ok and continue.
Again this procedure is very very very very very very slow.
Worse of all, you cannot leave it running by night. You must
press Ok a lot of times to clean the GPF.
9) Restart.
At last, setup will restart the PC. Exit Bochs. I recomend to make
a copy of WinMe.img just to save all your time.
10) Run bochs again
Setup will do some stuff ... just wait
After a while, the Start button appearch on the lower left corner
of the screen!
Just for safe, I executed within WinMe msconfig.exe, and in the
advanced tab set the Disk Compatibility mode". Also, I've turned
of the menu and windows animations, to speed thinks up a bit. Also
it may be a good idea to turn off scandisk on setup.
Do not forget to exit from Windows with the Shutdown menu ...
11) That's all
Now you can comment out the diskd line in the bochsrc.txt. WinMe.img
contains a working WinMe.
NOTE: if you lower the IPS, WinMe will be unstable ... surelly
a timing issue. But even if IPS is high, lowering
vga_update_interval and keyboard_serial_delay will help
on getting an acceptable usability.
DO not forget to use your Pentium 10 at 500 GHz to get a
good speed within Windows.
Some bugs i've found
- MSDOS Scandisk freeze
- Hw detection is very problematic
- If bochs is visible when it switchs from text mode to graphic mode,
the size of the window is correct. But if Bochs is minimized when
doing so, the size of the Bochs window is incorrect. It does not
take into account the height of the top banner (the one with the
disk icons, mouse, snapshot, etc), so the botton of the screen
is clipped.
- Dont expect to run WinMe at full speed unless you use your Pentium10 at 1500 GHz
- (not a bug, but a comment) The splash screen when booting/shutdown
WinMe is double height. I personally prefer to see the full image
as it was time ago. |
