Has anyone had success getting a Corsair Flash Voyager (1GB) to boot USB? If so, which method?

Corsair Flash Voyager 1GB USB Flash DrivePrepare the USB flash drive
Switch to root (not required if you boot “knoppix 1”) # su Check the current geometry on the drive (most likely recognized by the kernel as /dev/sda) # sfdisk -l /dev/sda Mine showed the following results: 63488 cylinders, 1 head, 32 sectors Multiply the three to obtain the total number of sectors: 63488 x 1 x 32 = 2031616 Supposedly, the boot partition should be less than 1024 cylinders, and 32 sectors per cylinder. So, I’ve adjusted the geometry as follows: total number of sectors / 32 / 1024 = # of heads 2031616 / 32 / 1024 = 62 And so, I’ve adjusted my geometry using sfdisk # sfdisk -f -C1024 -H62 -S32 /dev/sda sfdisk will next ask for the partition info. I’ve decided to have everything on one partition: sda1:0 1024 e * Press <ENTER> for all the others, (sda2, sda3, sda4) Basically, this sets the first primary partition (/dev/sda1) to start with cylinder 0 and end with cylinder 1024, it’s of type “e” (Win95 FAT (LBA)), and bootable (“*”) Reboot to reload with correct partition table for the USB flash drive Format the USB flash drive
Switch to root (not required if you boot “knoppix 1”) # su Format the drive # mkdosfs /dev/sda1 Make the USB flash drive bootable
You will need to download the bootusb and the DSL image files. I’ve used bootusb-0.8.img and dsl-1.0.1.iso, and put them in my /home directory. If you’re not able to copy the DSL image file to the /home directory, then store it at another location on your hard drive(s) and use that instead of “/home” below. Switch to root (not required if you boot “knoppix 1”) # su Write the boot sector # syslinux -s -o /home/bootusb-0.8.img /dev/sda1 Now, mount the drive # mount -t vfat /dev/sda1 /mnt/sda1 Create a temp directory and mount the bootusb image file # mkdir /mnt/tmp # mount -t vfat -o loop=/dev/loop0 /home/bootusb-0.8.img /mnt/tmp Copy files over to the drive and unmount the bootusb image file # cp /mnt/tmp/* /mnt/sda1 # umount /mnt/tmp Mount the DSL image file # mount -t iso9660 -o loop=/dev/loop0 /home/dsl-1.0.1.iso /mnt/tmp Copy files over to the drive and unmount the DSL image file # cp -r /mnt/tmp/KNOPPIX /mnt/sda1 # umount /mnt/sda1 All done. Try it on a PC that supports booting from USB. |
