If you don't have a floppy or USB key available to tranfer your openbsd.pbr with, you can copy it to another machine on your network, reboot into Windows, and copy it back. - The dd command above does allow me to save openbsd.pbr, and with this, I can dualboot. I just wanted to give a heads-up that if the FAQ doesn't allow you to dualboot, then the above might work. I thought that maybe it was a typo, since rsd0a and rwd0a differ by one letter, and those differing letters lie close on the keyboard. it is not a typo, just another possibility. maybe you want to have a look at the wd(4) and sd(4) manual pages.

If you don't understand what you are doing, you can very easily cause data loss. I don't want this section to be too just type this or HOWTO. Nick.

Eh? Look at http://www.openbsd.org/faq/faq4.html#Multibooting: # dd if=/dev/rsd0a of=openbsd.pbr bs=512 count=1 However, that's entirely dependent on the device to which you are installing, although the FAQ doesn't make that clear. Other parts of the install process make it very clear what drive (typically wd0 for IDE drives and sd0 for SCSI drives) is being used, what is not so clear to a new user is that 'rsdX' is the raw version of the 'sdX' block device, and 'rwdX' is the raw version of the 'wdX' block device. -- Matthew Weigel hacker [EMAIL PROTECTED]

Ah, now I see what you're typing. Yes, that part of the FAQ is only really valid if you boot from a SCSI drive. Some people do, some people don't. You obviously do not, so you naturally need to specify your IDE drive instead. Andreas -- Andreas Kahari
