Syslinux - Aug 2007 - "Boot error" on USB drive on some systems

I searched the mailing list and tried to find an answer, but didn't
see anything.

I have a Sandisk U3 Cruzer Micro 4.0GB flash drive.  I have removed
the U3 software via the uninstall utility on the U3 website.

The USB flash drive is on /dev/sdc

I have tried this with syslinux 3.11 (from Ubuntu 7.04) and syslinux
3.36 (from Ubuntu Gutsy).

I fdisked the drive and created a 750MB FAT16 partition (type 0x6) and
made it active.  It is /dev/sdc1

I cat'ed the mbr.bin (from the syslinux package) to /dev/sdc.  I have
also tried putting the MBR on using 'ms-sys'.

I then did: syslinux /dev/sdc1  (also tried syslinux -s /dev/sdc1).

I also setup stuff so that I would have a menu, by creating a syslinux.cfg.

When it boots up on one system, it works.  I get the menu.

On two other systems, all I see is "Boot Error".  Which I think comes
from syslinux, by looking at the first sector of the partition, I see
that string.

Is there anyway to get more debug output to help me figure this issue out?

Thanks,
John
