Hello, again, all:
My BIOS on THIS computer auto-detects the USB stick and
presents the boot option as: USB-HDD0: ...
MS-DOS boots fine to a C:\> prompt from the stick and
correctly maps the two 500MB partitions. It does not
see the other partitions at all.
Hope this helps. I'll be glad to provide any information
that will assist debugging this or run various programs.
I am reluctant to run FreeDOS FDISK, though. Without
an older EMM386, it is PROBABLY safe. I can run Linux
FDISK or dump MBR's from Windows or Linux.
Thanks!

OK, I can make this machine boot from the FreeDOS installation
on the hard drive...I believe it is the kernel from Beta9SR2 at
the moment...I get a new error, but it correctly identifies all the
partitions, boots to the correct one as C:, and can see them all,
even the stick:
The interesting parts are:
C: HD1, Pri[ 3], CHS=10569-0-1, start = 78028MB, size = 502MB
D: HD2, Pri[ 2], CHS=1784-0-1, start = 13994MB, size = 502MB
Drive is too large to handle, using only 1st 8 GB
drive 82 heads 255 sectors 63, total 0x3c3ff-76697244

F: HD2, Pri[ 3], CHS = 1848-0-1, start = 14496MB, size = 10001MB
boots to a normal C:> prompt. All partitions accessible and
dir c:, dir d:, dir e:, dir f: all work.
Removing the stick and rebooting, the message about "Drive is too large
to handle" goes away as does HD3 and partition E:. I get C:, D:, and E:
and they are all accessible and dir c:, dir d:, and dir e: work.
Frustrating...

Hello, all:
OK, I have arrived at home with the same 128MB memory stick. Prepared
just like Michael stated...development kernel, format 0.91V, etc..
I stuck it in the compaq computer I have at home and rebooted.
The interesting things are as follows:
WARNING: partition Pri:1 FS 06 has CHS = 15-92-13, not 14-254-63
C:HD1, Pri[ 1], CHS = 0-1-1, start = 0MB, size = 120MB

Bad or missing Command Interpreter
Enter the full shell command line:
command.com /p /E:256
Here, entering C:\command.com did nothing but repeat the error with
C:\command.com.
I have FreeDOS on what is D: installed. Entering "D:\command.com"
gets me to a C:\> prompt. DIR C: works and shows me the files on the
stick (kernel.sys, command.com, and a trivial autoexec.bat). DIR D:,
DIR E:, DIR F: all work fine. type c:\autoexec.bat works fine.
This is frustrating!
