I am using the 2.0.36pre7 kernel that comes with RedHat 5.2 on a DEC
HiNote VP laptop.  I installed PCMCIA services 3.0.5 during the RedHat
install.  The PNY compact flash memory, which is available and
CompUSA, SEARS and other stores, comes with an adaptor to fit in a
standard PCMCIA slot.  Linux recognizes the card when the compact
flash and the adaptor is inserted.  However, the laptop beeps with a
high then low beep which should mean the card wasn't initialized
properly.  For some reason it still works.  Linux automatically
creates a block device (/dev/hdc in my case.)  Refer to the
PCMCIA-HOWTO for more information about PCMCIA services.

Then I "mount /dev/hdc /mnt/flash"

It appears to be a ms-dos 8.3 file system.  The files are stored in a
directory that is named "im??????".  The last couple characters in the
directory name vary.  I'm not sure why.  The files are stored as jpeg
images within the directory and are named consecutively, i.e.:

dsc00001.jpg
dsc00002.jpg
...
dsc00010.jpg
dsc00011.jpg

Files can be copied to and from the memory, just like any other block
device.  If the directory is present without any files in it, then the
HP C30 complains that the card needs to be formated.  To format the
card, simply remove the directory.  This appears to be what the camera
does.  If a middle file is deleted, I think the camera actually
renumbers the files so that they are in consecutive order. 
Incidentally, I was able to take an image from the camera, alter with
GIMP, and copy it back to the flash memory with the name dsc00001.jpg.
 I was able to view the altered image on the camera but certain things
were a little strange.  For instance, the image turned up as a blue
sqaure in the small "photo proof" mode.  

You may use any of the information contained in this e-mail and post
it on the web but please label it as being anecdotal.  I am not a
programmer.  The only programming experience I've had was in Turbo
Pascal and therefore doesn't actually qualify as programming
experience :)
