[comp.os.msdos.misc] PCDOS 4.01 and MSDOS 4.01

Hi to all!

     I have a question here...  What is the difference between PCDOS 4.01
and MSDOS 4.01?  Bios calls, etc?  In a mail-order advertisement in 
PC-Computing, I noticed that the PCDOS 4.01 is much higher than the other
($135 v. $79).  How different are the codes?  Any features/commands that
one of them have that the other doesn't?  Can an original IBM run MSDOS,
and can a compatible run PCDOS?  (Read the previous question carefully,
please!  I know that original IBMs run PCDOS, and compatibles run MSDOS,
well, most of the time unless they use some other OS.)  Etc info?

Thanks in advance.  Please reply to the network so that we can all find out...

-Philip


PS.  If this is a FAQ, I'm sorry.  (I haven't seen it before though...)
      Is there a text file (via ftp) that I can find out more about this topic.
