USB Won’t Boot

If your USB seems messed up, or won't boot, you may want to try these steps, which will destroy everything on the USB.

From Linux

1.	Figure out which raw device is yours, WITHOUT the partition number. We'll assume it's /dev/sda. If you think it's /dev/sda1, use /dev/sda.

2.	As root do the following: (Note that mbr.bin is included in the zip file, so the instructions assume you start out as root in the mfgusb zip, unzipped on your hard disk.)

dd if=/dev/zero of=/dev/sda bs=512 count=100 sfdisk -R /dev/sda dd if=mbr.bin of=/dev/sda bs=1 echo ',,6,*' | sfdisk /dev/sda mkdosfs /dev/sda1 syslinux /dev/sda1

3.	Unzip the image, as in the instructions above. In the example, your device name is /dev/sda1, not /dev/sda.

mount /dev/sda1 /mnt/flash

cd /mnt/flash

unzip ~/Work/tree/output/product-demo-i386/release/mfgusb/mfgusb-demo-i386-20050710-090757.zip

cd ~ umount /mnt/flash

4.	Continue on with step 5 for either Windows or Linux, above

USB Won’t Mount

In cases where the USB CD-ROM drive is not recognized/mounted during manufacture, use the following Linux commands:

mknod /dev/sr0 –b 11 0

mount /dev/sr0 /mnt/cdrom

Then run proceed with the regular installation.
