+         <b>dd if=/dev/zero of=obsd_landisk.img bs=1024 count=1 seek=2000000</b>

+ </pre>
+         (Replace ftp.se.openbsd.org with a server closer to you, for
+         increased download speed.)
+   <p>
+   <li>You now need to make an ISO image of the entire directory you downloaded.
+         (I recommend using <tt>mkisofs</tt> for that purpose. If you don't
+         already have <tt>mkisofs</tt> installed on your system, you need

+         <b>rm -rf ftp.se.openbsd.org</b>      <i>(this directory is not needed anymore)</i>

+         <b>gxemul -x -E landisk -d obsd_landisk.img -d d:openbsd_landisk_4.1.iso bsd.rd</b>
+ </pre>
+         and proceed like you would do if you were installing OpenBSD
+         on a real landisk. The following hints are useful to get you
+         through the installation:
+         <ul>
+           <li>Terminal type = <b>xterm</b>
+           <li>root disk = <b>wd0</b> (the disk to install onto)
+           <li>Use the entire disk for OpenBSD = <b>yes</b>
+           <li>Create one big root partition (a) and a small swap partition (b). c is the entire disk.
+           <li>Do <b>not</b> configure the network. (The Realtek NIC
+                 found in the Landisk machine is not implemented yet
+                 in the emulator.)
+           <li>Location of sets = <b>disk</b>
+           <li>Is the disk partition already mounted = <b>no</b>
+           <li>Disk containing the install media = <b>wd1</b>
+           <li>Pathname to the sets = <b>4.1/landisk</b>
+         </ul>
+ </ol>
+ <p>Once the install has finished, the following command should let you

+ <p><pre>
+         <b>gxemul -x -E landisk -d obsd_landisk.img bsd</b>
+ </pre>
+ <p>As with most emulation modes in GXemul, the NIC in this machine is

- </pre>
-   <li>This is the tricky part: on redhat_mips.img, you need to create an MS-DOS
-         (!) partition table, and then an ext2 partition. This is what Linux
-         will then see as /dev/sda1.
-         <p>I recommend you run fdisk and mke2fs and untar the archive from within
-         Debian/DECstation or <a href="#debiancats">Debian/CATS</a> running
-         inside the emulator. (Alternatively, if you are on a Linux host,
-         you could use a loopback mount, or similar. This might require

+         <b>dd if=/dev/zero of=redhat_mips.img bs=1024 count=1 seek=2000000</b>
+ </pre>
+   <li>This is the tricky part: on redhat_mips.img, you need to create an MS-DOS
+         (!) partition table, and then an ext2 partition. This is what Linux
+         will then see as /dev/sda1.
+         <p>I recommend you run fdisk and mke2fs and untar the archive from within
+         Debian/DECstation or <a href="#debiancats">Debian/CATS</a> running
+         inside the emulator. (Alternatively, if you are on a Linux host,
+         you could use a loopback mount, or similar. This might require
