Hi! Just yesterday I've read your article from your site: http://www.wonkity.com/~wblock/docs/html/disksetup.html and I would want to know if you've written an article on how to build an 'im= g' file which has the same content as the 'disc1.iso' file but that will be b= ootable from a USB stick. In addition, I'll be happy if you can tell me in more detail why does even a= fter that I've extracted the content of the 'disc1.iso' file to a regular fo= lder and then 'reassemble' it with the command (on Linux): 'xorriso -dev /tm= p/my_FreeBSD_iso.iso -boot_image any system_area=3Dboot/boot0 -add /path/to/= the/extracted/disc1.iso/folder' and copy the new ISO file into my USB stick w= ith the dd command and then I reboot my PC and I see the boot prompt of the b= oot0 boot manager but I don't get an option to boot the FreeBSD system I've j= ust created. What's going wrong here?
