thanks for that da/ad clarification, that's something that will stay with
me now. :)

i tried the "sh MAKEDEV all" earlier after reading something on, but that didn't work.  i guess it's good it didn't because i
doubt i need to remake all the files.

however, i'm still getting the same issue with your method.  the following
errors appear:

mknod: ad4: Read-only file system
/sbin/mknod ad4

this happens about 5 times starting with ad4 and ending with ad4s4.  how
can i resolve this?

what has happend is that i've added a maxtor ata/100 controller.  this
older BX board only supports ata/33 so i figure i might as well use the
full potential of this drive.  the odd thing is that i've disabled native
motherboard controllers, so why is this drive still listed as ad4?

again, any and all help will be appreciated.
