	Hi, I'm running FreeBSD-5.0-current-20010501 on a Dell Inspiron
4000 laptop.  I am trying to use a Sandisk CompactFlash Pc Card Adapter in
the PCMCIA slot 0 to read a SanDisk CompactFlash memory card (80MB)
installed within it.  The card is recognized by pccard:

pccard: card inserted, slot 0
Jul 8 13:57:24 tc14 pccardd[180]: Card "SunDisk"("SDP")[5/3 0.6] [(null)]
matched "SunDisk" ("/.*/") [(null)] [(null)]
ata4 at port 0x240-0x247,0x24e irq 10 slot 0 on pccard0
ad8: 76MB <SunDisk SDCFB-80> [62/8/32] at ata4-master BIOSPIO]
Jul 8 13:57:29 tc14 pccardd[180]: ata4: SunDisk (/.*/) inserted

and is apparently installed as ad8.  So far so good.  However, since no
ad8s1 device exists I apparently cannot mount it.  I ran
/usr/src/etc/MAKEDEV ad8s1 and get:

WARNING: Driver mistake: repeat make_dev("ad8s1")
WARNING: Driver mistake: repeat make_dev("ad8s1")
mknod: ad8s1: Operation not supported
/sbin/mknod ad8s1

	Running mount on this gives:

tc14# mount_msdos /dev/ad8s1 /camera
WARNING: Driver mistake: repeat make_dev("ad8s1")
mount_msdos: /dev/ad8s1: No such file or directory

	Indeed there isn't an ad8s1 in /dev, so this is not a surprise.
There is, however, an ad8s1b, attempting to mount it gives:

tc14# mount_msdos /dev/ad8s1b /camera
mount_msdos: /dev/ad8s1b: Invalid argument

	The same happens for ad8s1a, the other device present in /dev with
ad8 in it.
	I think the problem here is that I don't understand the new 5.0
device system yet :(  Anyway, I apologize for my lack of knowledge, and if
anyone would be able to help me out I would apreciate it greatly.  Thank
you for your time.
