September 10, 201213 yr I have a new setup using a Gigabyte 78LMT-S2P. I can't see any sign in the "BIOS" that it sees the USB SD card plugged into an SD card reader. I have tried using different USB ports. I am using a Mac to setup the SD card. The SD card is 4GB Kingston with a Kingston MobileLiteG2 as the reader. I am attempting to use 5.0b12, but I don't think that has anything to do it with since it appears to not even be getting to the contents of the card. Error message "Missing operating system" or sometimes it is just stuck at "Verifying VMI Data pool...". ---edit--- Added my discoveries below. FIXED - so, unfortunately I didn't approach this scientifically... having said that.... I changed the "hybrid" EFI/BIOS to run exclusively as BIOS, and when I used my sd card with reader (on the MLB direct connections from the back of the tower) I was able to boot up properly and everything worked. I cannot tell if the "force BIOS only" mode was necessary. It SEEMS to be that the ability to format as FAT instead of FAT32 (only option for a Mac) was the difference here. So in summary. Check your EFI/BIOS hybrid settings, format as FAT not FAT32...and possibly: do it on a windows machine? Unless someone knows of a way to format as FAT in Mac OS X.
September 10, 201213 yr Author Just to add, since I forgot to mention this earlier. The SD card is formatted with MBR and FAT 32. And I have already verified it is named "UNRAID".

Error message "Missing operating system" or sometimes it is just stuck at "Verifying VMI Data pool...". It will probably list the USB drive as a hard-disk. Most BIOS do that when the size of the flash memory goes over 512Meg or 1Gig. Look under the list of hard disks.

September 11, 201213 yr Since you formatted on a Mac, make sure the FAT32 partition is labeled "UNRAID" and not the flash drive itself. In Disk Utility you can name a disk and a partition two different things so make sure both are "UNRAID".

In Disk Utility you can name a disk and a partition two different things so make sure both are "UNRAID". I will double check. For sure the partition is named specifically that, I wasn't aware you could rename the device.
September 12, 201213 yr Make sure the partition is marked bootable. Not sure how to do this with a Mac. I'm pretty sure "fdisk -l" in linux will tell you if it is marked as such.
September 12, 201213 yr Author Make sure the partition is marked bootable. Not sure how to do this with a Mac. I'm pretty sure "fdisk -l" in linux will tell you if it is marked as such. I am.... 'mediocre' with Linux. When I get home from work I will try this. What results would show (if that command works in Terminal) for bootable vs not bootable?
September 13, 201213 yr The flash must show up in BIOS for it to be used. None of the suggestions will correct this issue.
September 13, 201213 yr Author I tried a different boot device. I had a 2GB USB flash drive, used a work computer with Win 7. BIOS instantly recognized it. Booting from it, I can select UNRAID or memtest. Then it loads bzimage, then bzroot... about 5 lines of ".........", then "Boot Failed: please change disks and press a key to continue". So, tomorrow I'm going to bring my usb reader and SD card and load UNRAID on it from there. Having said that, ideas why it fails the bootup process?
September 13, 201213 yr Put the SD card in the other slot. Mine has the same problem if it's inserted in the small slot.
September 13, 201213 yr Are you using a regular SD card (big) or a microSD. microSD won't work I think. Better use a normal SD card that fits in the big slot.
September 13, 201213 yr I use a micro in an adaptor. The same freeze happens if I put the micro in the micro slot.
September 13, 201213 yr Author I use a micro in an adaptor. The same freeze happens if I put the micro in the micro slot. That is interesting... in this case I am using a full sized card in a full sized slot. Some of these little kinks in the system should probably go to the Wiki article about USB Drive troubleshooting though.
September 13, 201213 yr I use exactly the same as you a SD card in a mobiliteg2. I have no problem booting unraid on the 2 supermicro boards I have. I set it as the first boot device. When I put the reader in my Win 7 laptop it gets detected immediately and its folder gets shown.
September 13, 201213 yr Author Windows and Mac OS X have had no problems identifying the sd card/reader. However, I have not had luck having the BIOS of the UNRAID computer detect anything. When I get home from work today I will try out again with FAT formatted (instead of FAT32 from OS X), and done in Windows 7. Then I'll see how that goes.
September 13, 201213 yr Have you run "make_bootable.bat" batch file that is included in unraid downloads?

The stick should show in the BIOS at least. Sorry, forgot the OP where you mention the motherboard.
September 14, 201213 yr Author Have you run "make_bootable.bat" batch file that is included in unraid downloads? I didn't think you needed to do that if you use a Mac (being as it is a .bat file). But when I did the setup with Win 7, yes I did run the file.

Didn't know that board had an EFI BIOS.
September 15, 201213 yr Weird, because my last board was EFI and I formatted my thumb drive as FAT32 and didn't need to do any configuring at all. Just plugged it in straight out if the box and booted with no issues. Must be because of the card reader.

Didn't know that board had an EFI BIOS. I am not an EFI expert, but my reading on it gives me the impression it is not a true EFI system, some sort of hybrid system. But yeah, happy it worked.
