ibm microdrive and file systems

Hi all,

I just purchased an ibm microdrive for my iPaq. I have looked at the
mailing list archive, but still have a few questions:

what /dev does the microdrive use? where does it connect on /mnt ? do I
just create a new directory in /mnt ?

what file systems does the kernel support? Is there a specific file system
I should be using on the microdrive?

Als, is there any info someone could point me to regarding the file system
of the ipag?

What is the rom and ram file structure? what is mounted where?

Thanks for your help
