Subject: CP/M disk logins

The answer to this is probably obvious, to those who know the answer.

What flag or field or whatever shows that a disk has been 'logged in'?
This comes up two ways:

     o Something used by BDOS to tell it to 'login' a disk and build a 
       directory check table and allocation table.

     o Some way for the BIOS to know that the disk drive has a new disk
       and it needs to be checked (i.e. density, format, etc.).  Obviously
       the BIOS doesn't want to do this everytime SELDSK is called.

I strongly suspect a word in the DPH table, but which one?

??????????

  tnx
