Hello, again:
I just booted the 2005 ODIN (from a CD) and used the
"SYS" command on the USB stick. It still boots to a C:\>
prompt, a DIR C: still shows me the FAT32 data partition,
and I have a THIRD partition boot sector. The MBR is
identical except for the "magic bytes."
(DIR C: should show me the USB stick I just booted
from. DIR D: yields an error instead of the FAT32
partition with MSDOS on it and DIR E: gives two
errors instead of the FAT32 data partition).
That tested both the ODIN 2005 kernel and the development
kernel and the ODIN boot sector.
Any ideas?
Thanks!

Hello, all:
OK. I'm trying a different experiment, and a more methodical one.
(I have a different computer and a different USB stick). I am
using the HP Utility SP27213. This utility detects whether you
have files named kernel.sys/command.com in the directory you point
it at or msdos.sys/io.sys/command.com.
If I run the utility, instruct it to format the USB stick and
use MSDOS files, it does so and the resulting USB stick boots under
MSDOS and runs fine. No problems.
If I run the utility, instruct it to format the USB stick and
use FreeDOS development (February 14, 2006) files, FreeDOS boots
to a C:\> prompt all right, but a "dir c:" shows me the files
from an extended FAT32 partition on my hard disk, not the USB stick!
The MBR's in these two cases are identical except for some
so-called "magic bytes" at 01b8-a which are some sort of
Windows timestamp.
The boot sectors are not the same...not even close. The HP utility
obviously knows about the FreeDOS kernel and applies an appropriate
boot sector.
The partition type on the USB stick is type 14 (decimal),
WIN95 DOS 16-Bit FAT, LBA-mapped.
Any suggestions on how I can debug this?
