I have a CompactFlash card working myself, so that I can easily share
files (and backups) between my laptop and my TPGpro Palm Pilot.

The `function' field here is quite important -- it tells you that PCMCIA
sees the card as a `fixed disk' device (hard disk), not a `memory'

Yup. This is a feature(tm) of CompactFlash cards. They actually have a
little chip in them that pretends it's really a hard disk drive, rather
than a block of memory.

What you need to do is ensure that you have the `ide_cs' module
available in the `pcmcia' directory. That is the module needed to access
the card.

When you plug the card in, you can then mount it, fdisk it, etc, just
like a hard disk. `/var/log/kern.log' or a similar file will spit out
the logging indicating which drive it is -- but, assuming you didn't add
any extra drive controllers, the CF card lands as `hde'.

If you read the section in the PCMCIA HOWTO about IDE devices, that
should cover the setup and stuff.

Let me know if you need more help and I will try and write a simple
cookbook to make it work.


You want to be famous and rich and happy, but you're terrified you have
