Good news/bad news: I've successfully booted BeOS from the boot0 MBR. (Incidentally, on a 256 MB Compact Flash card on an IDE adapter.) However, when installed on my main box, with a real harddisk of 120 GB, it fails. The menu is there, but it just beeps when I press a key, and nothing happens. (In 'boot0.S': " * User's last try was bad, beep in displeasure." Anybody fluent in assembly?) The HD size shouldn't be a problem. My BSD box has a 200 GB harddisk, and it works great, so perhaps I'm missing some option. I think I tried the "packet" option though, which is necessary for large disks. This hardware is a little odd, BTW. Bootman complains, but only when booted off a CD, about not being able to get the BIOS drive number of the /boot volume. Maybe that's it. http://www.kirilla.com/tmp/bootman5.zip Put the 'boot0' MBR file in /boot/, and spell out the full dev path: > boot0cfg -B /dev/disk/ide/ata/0/master/0/raw (-Bv toggles verbosity on, which is probably a good idea.) And keep a BeOS CD handy to reinstall bootman, should you get locked out. Backing up your files might also be a good idea. /Jonas Sundström. www.kirilla.com
