f3500010b7 Moved open-ATAPI-as-RW check to before open-first-time check.. otherwise 
you can open an ATAPI device as RW if it's already opened for read.

7de7ca978d Security check on physical address to be < 16 MB (ISA DMA uses 24-bit 
addressing, which can address 16 MB max).

74711a3b14 Check if kernel calls is allowed (from process' call mask) added. Not yet 
enforced. If a call is denied, this will be kprinted. Please report any such
errors, so that I can adjust the mask before returning errors instead of
warnings.

Wrote CMOS driver. All CMOS code from FS has been removed. Currently the
driver only supports get time calls. Set time is left out as an exercise
for the book readers ... startup scripts were updated because the CMOS driver
is needed early on. (IS got same treatment.) Don't forget to run MAKEDEV cmos
in /dev/, otherwise the driver cannot be loaded.

e561081545 Miscellaneous clean ups and fixes to the kernel. 
Support for FLOPPY in boot image. (Set controller=fd at boot monitor.)
Moved major device numbers to <minix/dmap.h> (maybe rename to dev.h?)

b69ca94efb Fixed 'bug' in log driver that caused kernel messages not to be displayed. 
This was caused by a change in the shared driver code. Not log's fault.

Renamed #definitions of driver process numbers, e.g., TTY now is TTY_PROC_NR.
All known (special) processes now have consistent naming scheme. Kernel tasks
don't follow this scheme.

52965b6f17 Various updates to support dynamically starting drivers. 
Output during initialization should be suppressed. Unless an error occurs.
Note that main() can now be main(int argc, char **argv) and arguments can
be passed when bringing up the driver.

d62e515660 Small update to SYS_IRQCTL -> setting an interrupt policy now allows the caller 
to provide an index (0 .. 31) that is passed in the HARD_INT message when an
interrupt occurs. The NOTIFY_ARG field contains a bitmap with all indexes for
which an interrupt occured.

435dd377ed Added an IDENTIFIED flag that is set on successfully identified drives. 
This avoids the bug scenario where DEAF but not-w_identify()d drives are
never properly identified, but are seen as real devices.

09830fc33e Allowed printing diagnostic messages (either from system processes or the 
kernel) to the log driver. The log driver forwards such output to the TTY.

Changed driver_task() not to send a reply if the return value is EDONTREPLY.
