I tried to play with usb key yesterday. Yes, when I copied mbr from the other computer, computers didn't hang anymore. Of course, that mbr is not suitable to boot OpenBSD as it points to grub which doesn't exist in this usb key, however I successfully booted OS from CD (boot hd0a:/bsd). So, I have question. Can I install grub (with ffs support?) to openbsd from ports or I need to compile it and configure it manually? Grub manual points that booting method is the same as NetBSD (however, does it mean that I need to write --type=netbsd or --type=openbsd?). Thank you in advance. Regards, Andrius V
