From 2f86936a077e531bc6fed8688d33030ae28ea45a Mon Sep 17 00:00:00 2001

Subject: Finished device configuration database work for all ISA devices
 (except `ze') and all SCSI devices (except that it's not done quite the way I
 want).  New information added includes:

-	A text description of the device
-	A ``state''---unknown, unconfigured, idle, or busy
-	A generic parent device (with support in the m.i. code)
-	An interrupt mask type field (which will hopefully go away) so that
.	  ``doconfig'' can be written

This requires a new version of the `lsdev' program as well (next commit).
