port-i386/44563: boot loader prompt doesn't read keyboard input on a MacBook1,1
check for keystroke (int 16h, AH=01h) before getting keystroke (int 16h,
AH=00h), fixes bootloader keyboard input with Apple firmware, from Taylor R

Add wait_sec() which uses BIOS function call INT 1Ah/AH=00h (GET SYSTEMTIME)
and use it for large delays (in seconds) instead of delay() that uses
INT 15h/AH=86h (WAIT) in microsecond because the latter one can't provide
precise delays on emulators.
Fixes PR port-i386/43156 (NetBSD bootloader countdown runs at 1/20 speed
in qemu 0.12).
No particular comments on the PR and port-i386@.

int 15h/AH=86h (WAIT) doesn't work properly on all hardware and emulators, so
for the countdown use the more coarsely grained sleep implementation based
on int 1ah/AH=00h (GET SYSTEM TIME).

mbalmer | Have the boot countdown on i386 display "starting in N seconds." instead
of "starting in N" and eliminate a use of sprintf. Note that on
some rare machines it can be that the BIOS does not provide the delay
function. On such machines the countdown will almost immediately count down
to zero display "starting in 0 seconds."; apparently the net4801 is such a
machine.

Make a baud rate of zero cause the baud rate divisor be read and converted
to the current baud rate.
That way we use the same baud rate as the system BIOS (or whatever).
Rather useful for pxeboot.

mycroft | branches: 1.19.6;
Make awaitkey() poll once even if the timeout is 0. This also fixes a problem
where a keypress within the last polling interval would not be noticed.
Add a new function, conisshift(), which is used to detect whether a shift key
is pressed. Use this via awaitkey() to allow interrupting the boot by holding
down shift (similar to LILO).
This allows setting the timeout to 0 and still being able to use the boot
program.

dsl | branches: 1.18.4; 1.18.6;
Allow the com port base address to be specified by the user (via installboot)
rather than taking the value from the bios.
Should allow the system to use a serial console that is also a 'bios serial
console' and isn't in the bios serial port table.
Probably fixes (with a few other changes) PR port-i386/9236

lukem | Overhaul MBR handling (part 1):
<sys/bootblock.h>:
* Added definitions for the Master Boot Record (MBR) used by
a variety of systems (primarily i386), including the format
of the BIOS Parameter Block (BPB).
This information was cribbed from a variety of sources
including <sys/disklabel_mbr.h> which this is a superset of.
As part of this, some data structure elements and #defines
were renamed to be more "namespace friendly" and consistent
with other bootblocks and MBR documentation.
Update all uses of the old names to the new names.
<sys/disklabel_mbr.h>:
* Deprecated in favor of <sys/bootblock.h> (the latter is more
"host tool" friendly).
amd64 & i386:
* Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to
be consistent with the naming convention of the msdosfs tools.
* Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1
and it's confusing to have two functionally equivalent bootblocks,
especially given that "ufs" has multiple meanings (it could be
a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems).
* Rework pbr.S (the first sector of bootxx_*):
+ Ensure that BPB (bytes 11..89) and the partition table
(bytes 446..509) do not contain code.
+ Add support for booting from FAT partitions if BOOT_FROM_FAT
is defined. (Only set for bootxx_msdos).
+ Remove "dummy" partition 3; if people want to installboot(8)
these to the start of the disk they can use fdisk(8) to
create a real MBR partition table...
+ Compile with TERSE_ERROR so it fits because of the above.
Whilst this is less user friendly, I feel it's important
to have a valid partition table and BPB in the MBR/PBR.
* Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent
with other platforms.
* Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that
we can boot off FAT partitions.
* Crank version of /usr/mdec/boot to 3.1, and fix some of the other
entries in the version file.
installboot(8) (i386):
* Read the existing MBR of the filesystem and retain the BIOS
Parameter Block (BPB) in bytes 11..89 and the MBR partition
table in bytes 446..509. (Previously installboot(8) would
trash those two sections of the MBR.)
mbrlabel(8):
* Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code
to map the MBR partition type to the NetBSD disklabel type.
Test built "make release" for i386, and new bootblocks verified to work
(even off FAT!).

dsl | Change all .S files to use .code16 and .code32
Support 32bit addresses >64k as valid on bios calls.
Move stack for dosboot and biosboot to >64 so stack doesn't hit data.
Use disk sector number passed by mbr code to select default partition
(the mbr code doesn't do this yet).
NB only biosboot and dosboot have been tested so far.
