+List of bugs discovered in 1.7.1.  Please report more bugs to kjb@cs.vu.nl.
+
+- The updates to the BIOS driver have only been tested on a few machines.
+  If it doesn't work on your machine then type 'processor=86' to the
+  Boot Monitor to force Minix into real mode.
+
+- The XT and PS disk drivers do not work, use the BIOS driver instead.
+
+- Disabling all WINI drivers in <minix/config.h> leads to a compilation
+  error.  (The definition of NR_TASKS in <minix/const.h> is wrong.)
+  Leave at least one of the WINI drivers enabled.
+
+- The AT disk driver uses a scratch buffer in its initialization
+  routine that has not been initialized.  This error is masked if the
+  Adaptec SCSI driver is initialized first, because it will then
+  initialize the scratch buffer for the AT driver.  This is why the
+  installation ROOT floppy works.  A kernel with only the AT driver
+  fails on an old AT disk, but an IDE disk will seemingly work.  The
+  bug will cause the driver to report wrong parameters to 'part'.
+  A fix to this bug is found in fixes/fix-1.
