I apologize,
for mistake all my mailbox went deleted so I lost the replies to my help
message... I Ask it again then...

I Am not able to mount msdos filesystems

mount_msdos /dev/wd0a /mnt

wd0 is my C hard drive on Win98, my open bsd is on sd0 my SCSI disk
I Csnnot mount disks of msdos filesystem, I always get the message "Device
not configured"

What I'm typing wrong in the command ??
thanks
