Re: [atv-bootloader] Booting ATV w/ ATV OS off USB

I'd like to remove my internal ATV and boot from USB. I have no need for 40GB of space since all of my media is on SMB/AFP share or streamed. This would also cut down on heat and power consumption.Just wondering if anyone has tried this. I've actually created all the partitions and copied recovery media just like this was a new drive onto a 4GB USB drive but haven't removed the internal drive yet to know if it will work. I realize that I'll likely have to off-line patchstick the bootable USB, but that shouldn't be an issue. It works :) I seem to remember that the AppleTV efi firmware takes a peek for the internal disk even if booting off a USB drive. Boot might be a little longer, can't remember now. You just have to try it, it will boot though with the internal disk removed. (excuse me if this is a duplicate; I didn't see that it came through on googlegroups). Thanks, Scott! OK, I finally got around to trying this.. :) Setup the drive, setup files on the recovery partition, opened the Apple TV, removed the IDE drive and attempted a boot off USB. The activity light on the USB device flashed for a short period (maybe 4 seconds), then it was off, then about 30 seconds later it flashed for about 10-15 seconds. Apple logo is on the screen, but nothing else happens. I let it sit here for about 15 minutes, then it appeared to reboot and start the same cycle over again.The whole time the front light on the ATV is blinking yellow. The USB drive is only 4GB (I have some larger ones coming) and I'll try those later this week. Any ideas? Thanks in advance!

EFI firmware can boot the kernel but the kernel does not have USB support until after USB support gets added once the file system is up via the USB hacks. So you have classic chicken/egg problem when booting atv(osx) off a USB HD drive. -- To post to this group, send email to atv-bootloader@googlegroups.com For more options, visit this group at http://groups.google.com/group/atv-bootloader?hl=en
