4.4 - Multibooting OpenBSD (i386, alpha)
OpenBSD & NT (or XP)
To multiboot OpenBSD and NT (or XP), you can use NTloader, the bootloader
that NT uses. To multi-boot with NT, you need a copy of your OpenBSD pbr.
After running installboot, you can copy it something like this:
# dd if=/dev/rsd0c of=openbsd.pbr bs=512 count=1
Now boot NT and put openbsd.pbr in c:. Add a line like this to the end of c:\
When you reboot, you should be able to select OpenBSD from the NT loader menu.
There is much more information available about NTloader at the NTLDR Hacking
On Windows XP you can also edit the boot information using the GUI, see the
XP Boot.ini HOWTO at http://support.microsoft.com/default.aspx?scid=kb;EN-US;q289022
OpenBSD & Windows or DOS (i386)
To boot OpenBSD along with Windows 3.1, Windows95, or DOS you must use a boot
loader on the system that can handle OpenBSD, Windows, and DOS! Some
bootloaders of choice are osbs20b8.zip or The Ranish Partition Manager. Both of
these are able to boot OpenBSD partitions.
OpenBSD & Linux (i386)
Please refer to INSTALL.linux, which gives indepth instructions on getting
OpenBSD working with Linux.
