I also just removed the rbf1773 driver from os9boot and I'm still 
getting the *m error.  I don't think my os9boot file is too 
large.  Maybe I'm using the wrong memory request call?

Which of these needs to be used in the the boot module for Level Two?

          os9   F$BtMem
          os9   F$SRqMem
