Stefan Koehler hat dazu vor wenigen Tagen eine Anleitung in die Linux- 
ger gesetzt:

Absender   : stk_bEi_warlock.kbbs.org  (Stefan Koehler)

nachdem ich hier berichtet hatte, dass XP 3.12 bei mir im DOSEmu voellig
reibungslos laeuft, haben etliche Leute nachgefragt. Ich stelle Euch also
hier einmal mein Setup vor:

==== Vorweg meine Technik:

Pentium P100, 2 IDE-Festplatten, Grafikkarte Spea V7 S3, 48 MB RAM.
Die primaere Bootpartition fuer DOS und Win95 ist C: = /dev/hda1, XP lebt auf
F: = /dev/hda6.
Die DOS-Programme fuer den EMU aus /var/lib/dosemu/commands liegen in
C:\EMUUTILS, das auch im DOS-Pfad eingetragen ist.
Uebliches Modem an COM2, UUCP-Verbindung mit XP zu meiner Mailbox.
SuSE 6.1 mit allerdings neuerer DOSEmu-Version 0.98.8.0, die ich stabiler
finde als die auf der SusSE CD.
Sound und CD sind unter DOS nicht konfiguriert. An den Einstellungen fuer X
habe ich nicht gedreht, die sind so noch unveraendert.

Den EMU starte ich mit folgendem Skript dosxp (der user muss natuerlich die
DOS-Filesystems mounten duerfen):

umount /dosc
mount -t vfat /dev/hda6 /dosf
dos
mount /dosc

Dies ist so noetig, weil C: bei mir beim Linux-Boot automatisch gemountet
wird. Wenn man aber als $_hdimage kein disk image, sondern direkt /dev/hdxx
eintraegt, darf die betreffende Partition fuer EMU nicht gemountet sein, daher
wird sie hier vor dem EMU-Start umounted und hinterher wieder gemountet.
/dosc bzw. /dosf sind die mountpoints der jeweiligen DOS-Partitionen.
Fuer den nachher (4.) folgenden lredir-Aufruf (noetig, weil XP auf einer
anderen Partition als C: liegt) muss F: unter Linux gemountet sein.


==== 3. ====


Fuer den DOS-Start im EMU bestehen nun folgende DOS-Dateien in C:\ :

==autoexec.emu:

_bEi_ECHO OFF
PROMPT DOSEMU $p$g$g
SET GDC=C:\SPEA\GDC
rem Das ist der Pfad fuer meine Grafikkarte
SET PATH=%PATH%;EINIGES-MEHR;C:\EMUUTILS
doskey


==config.emu:

device=c:\windows\ramdrive.sys 1000 /e
rem  Im Moment startet hier nur eine RAMdisk.


==== 4. ====


Nun sollte man am DOS-Prompt angekommen sein. Ich starte XP mit folgender

 XPEMU.BAT in C:\

c:\emuutils\lredir f: linux\fs\/dosf
f:
cd xp
xp


D.h., der Weg vom Linux-Prompt ist:

LINUX: ./dosxp
[nun sollte der DOS-Prompt erreicht sein ]
im DOSEMU  XPEMU
 ... fertig.
XP normal verlassen, und das Programm EXITEMU in C:\emuutils beendet dann
den EMU.


Eigentlich ist das alles gar nicht so kompliziert, wie es klingt. Sehr
geholfen hat mir, auf hdimages zu verzichten und als $_hdimage direkt die
DOS-Boot-Partition einzutragen. Auf diese Partition sollte dann aber nur der
EMU schreiben. Noch viel einfacher duerfte es sein, wenn XP auf der DOS-Boot-
Partition liegt, dann braucht man den lredir-Umweg nicht.

Ich hoffe, ich habe einigen etwas weitergeholfen.

Viele Gruesse, have fun -
