Here's the quick and dirty on installing WinNT 4.0 in bochs.
|
|
|
|
|
For reference, the version I installed was WinNT 4.0 Build 1381
|
|
|
|
|
on an internal version of bochs-991026a+.
|
|
|
|
|
<p>
|
|
|
|
|
There are a couple approaches you could take. You could
|
|
|
|
|
copy contents from the CDROM distro to a hard disk image file
|
|
|
|
|
and then install from there. I wanted to test the
|
|
|
|
|
CDROM emulation in bochs, so I installed directly from
|
|
|
|
|
the WinNT CD with no extra copy needed. These instructions
|
|
|
|
|
are from a corresponding install.
|
|
|
|
|
<p>
|
|
|
|
|
First, you need to configure bochs with CDROM emulation.
|
|
|
|
|
You need this even if you are not going to use the direct
|
|
|
|
|
CDROM emulation, otherwise NT won't recognize the hard
|
|
|
|
|
disk emulation (legacy IDE controller). Thanks to Chris
|
|
|
|
|
Smith for pointing this out as well as some additional
|
|
|
|
|
hacks for booting WinNT.
|
|
|
|
|
|
|
|
|
|
<pre>
|
|
|
|
|
unix> ./configure --enable-cdrom ...
|
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
|
|
Next, you need to create a hard disk image file big enough
|
|
|
|
|
to install WinNT. I made one using the following command.
|
|
|
|
|
Refer to
|
|
|
|
|
<A HREF="install.html#Creating a hard disk image file">
|
|
|
|
|
Creating a hard disk image file</A>
|
|
|
|
|
for more on creating disk image files.
|
|
|
|
|
|
|
|
|
|
<pre>
|
|
|
|
|
unix> dd if=/dev/zero of=../483M.NT40 bs=512 count=967680
|
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
|
|
You will need to give bochs a description of the geometry
|
|
|
|
|
of your disk drive in .bochsrc. Following was my entry.
|
|
|
|
|
While you're editing .bochsrc, uncomment or add the cdromd
|
|
|
|
|
directive which tells bochs to use your workstation's CDROM drive
|
|
|
|
|
and the CD that is in it.
|
|
|
|
|
|
|
|
|
|
<pre>
|
|
|
|
|
diskc: file=../483M.NT40, cyl=1024, heads=15, spt=63
|
|
|
|
|
cdromd: dev=/dev/cdrom, status=inserted
|
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
|
|
OK, you will need a boot floppy to kick things off, so that
|
|
|
|
|
from DOS you have access to the CDROM to run the
|
|
|
|
|
install program. Make a DOS boot floppy with FORMAT and
|
|
|
|
|
FDISK on it. You will also need a driver for the CDROM.
|
|
|
|
|
Use one for a standard IDE CDROM. For example, you can
|
|
|
|
|
download one from
|
|
|
|
|
<a href="http://www.driverzone.com/drivers/atapi/">The Driver Zone</a>
|
|
|
|
|
in atapi.zip, called GSCDROM.SYS. I put the driver and MSCDEX.EXE
|
|
|
|
|
all on the boot floppy.
|
|
|
|
|
<p>
|
|
|
|
|
I used a CONFIG.SYS and AUTOEXEC.BAT that look like the following.
|
|
|
|
|
Don't forget if you're editing in Unix land, use the '-t' option
|
|
|
|
|
to mcopy to transfer text files to/from Unix and your image file.
|
|
|
|
|
|
|
|
|
|
<pre>
|
|
|
|
|
[config.sys]
|
|
|
|
|
DOS=HIGH
|
|
|
|
|
FILES=30
|
|
|
|
|
|
|
|
|
|
LASTDRIVE=Z
|
|
|
|
|
DEVICE=a:\GSCDROM.SYS /D:MSCD000 /v
|
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
|
|
<pre>
|
|
|
|
|
[autoexec.bat]
|
|
|
|
|
@ECHO OFF
|
|
|
|
|
PROMPT $p$g
|
|
|
|
|
|
|
|
|
|
\MSCDEX /D:MSCD000 /L:D
|
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
|
|
At this point you're all set to begin the installation. Fire
|
|
|
|
|
up bochs:
|
|
|
|
|
|
|
|
|
|
<pre>
|
|
|
|
|
unix> bochs boot:a
|
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
|
|
Then fire up the WinNT install program:
|
|
|
|
|
|
|
|
|
|
<pre>
|
|
|
|
|
A:> d:\i386\winnt /b /s:d:\i386
|
|
|
|
|
</pre>
|
|

This page not finished yet. I wanted to get this release
|
|
|
|
|
to people who really needed the changes. The next release
|
|
|
|
|
should have better help on installing NT4.0. Here are
|
|
|
|
|
some tips though, that may help.
|
|
|
|
|
<ul>
|
|
|
|
|
<li>Every time NT reboots the machine, bochs panics out. This
|
|
|
|
|
is OK.
|
|
|
|
|
<li>Tell WinNT not to generate an emergency boot disk for now.
|
|
|
|
|
Otherwise it will hit the floppy Format Track command which is
|
|
|
|
|
not implemented yet. (I may do that next)
|
|
|
|
|
<li>After you've done the intial part where data is transferred
|
|
|
|
|
from the CDROM to the hard disk image file and the machine
|
|
|
|
|
is rebooted (bochs panics out), change the cdromd directive
|
|
|
|
|
in .bochsrc from 'status=inserted' to 'status=ejected' before
|
|
|
|
|
firing up bochs again. Otherwise NT will use a CDROM
|
|
|
|
|
command which is not implemented fully yet.
|
|
|
|
|
<li>I told NT not to install a driver for any mouse, and specificially
|
|
|
|
|
to use standard VGA in the configuration phase. Don't know if
|
|
|
|
|
this was necessary.
|
|
|
|
|
</ul>
|
|
|
|
|
|
|
|
|
|
I'm going to give the install another spin after I fix some other
|
|
|
|
|
things and rehash this page.
