Attached, please find the information that you requested.  It was taken
from console 2 while in the Debian installer (Sarge, 1/17/05).  It shows
the partition table, and parted acts as it had under Knoppix.

Thanks for any help.  If the Debian installer could just accept the
partitions that I already have, without insisting on invoking parted,
I think it would solve my problem.				- Gene

Here are the results of my tests while running the Debian installer
from Sarge (1/17/05).  I ran the installer until the point where it
failed to recognize my partitions.  I then shifted to console 2,
and performed the tests shown here.  Please excuse some formatting issues
from my output.  I didn't have the full set of UNIX tools.	- Gene

[I had originally created the partitions above using
 Mandrake 7.1 Drake (an obsolete version of Mandrake, but it
 was handy, and the parted on Knoppix 3.6 was not working for me.)
 Note, below, that parted says that the partitions were created by
 software that didn't have the right geometry.  But parted says it
 can still continue, and it turns out that parted cannot continue.]
[They are: sda1 (ntfs/Windows XP), sda3 (swap), sda5 (vfat),
	 sda6 (ext3/Knoppix 3.6), sda7 (ext3/home), sda8 (ext3/Knoppix 3.7) ]
