[syslinux] USB vs. ATA with Compact flash

[Collins, Cris L.]

Pre7 did not work "boot error". 3.11 works fine for me, but if you need 
me to test future versions let me know. 
  I am using the CF with a USB bridge. It is partitioned as follows:
  Disk /dev/sdb: 4076 MB, 4076642304 bytes
255 heads, 63 sectors/track, 495 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1         390     3132643   83  Linux
/dev/sdb2             391         495      843412   82  Linux swap / Solaris
   

It is formatted EXT2:
  /dev/sdb1 on /mnt type ext2 (rw)
   

The extlinux.conf file:
  prompt 1
DEFAULT Test
TIMEOUT 300
LABEL Test
        kernel /boot/vmlinuzQ
        append initrd=initrd-2.6.30.9.img root=/dev/sda1 ro
   
  The fstab on CF:
  cat /mnt/etc/fstab
LABEL=/F            /                    ext2    defaults        0 0
tmpfs               /dev/shm             tmpfs   defaults        0 0
devpts              /dev/pts             devpts  gid=5,mode=620  0 0
sysfs               /sys                 sysfs   defaults        0 0
proc                /proc                proc    defaults        0 0
LABEL=Fswap         swap                 swap    defaults        0 0

   
  Not sure if this useful:
   smartctl -a /dev/sdb -T permissive

  Let me know if you have any other questions. Thank you for your time.

Also, how are you using the CF card?  Is it partitioned or
unpartitioned?  What file system?  What "geometry"?  Could you provide
some more related info?

If 4.04-pre7 doesn't resolve the issue, I have an image that will look
similar (if it's unpartitioned) from the standpoint of the BIOS but
will instead dump data and another image that can be dropped onto the
partition to dump the same data (I'm still in the process of preparing
it for mainline inclusion).  Both _will_ destroy your file system.
