Add support for switching menu format between numbers and letters. Will
prefer numbers, but will automatically switch to letters if > 9 options
and timeout > 0 (i.e. need a single key press to choose).
Menu format can be explicitly set in boot.cfg file.
Add support for reading numeric choices of more than 1 digit.
Why is there a "Makefile.boot" used here, and a "Makefile.booters"
used one level up, with redundant stuff between both of them? This all
used to be so clean...
For now, we include kernel revision as a way of allowing users to
notice that boot blocks have gotten very old, so the first line of the
printout looks like this (depending on the particular block):
>> NetBSD/x86 BIOS Boot, Revision 3.4 (from NetBSD 5.0)
This may be changed a bit pending feedback. (Some people think that
the kernel revision shouldn't be there at all, for example.)
Part of the project to assure that bit-identical sources produce
bit-identical release binaries.
We now wrapper the open call for a module with module_open. It first
attempts to open the module_path munged path, if this fails it then tries
to open the original path.
This allows tftp files to be located correctly.
are taken from boot/boot2.c.
This allows an install to be started by running:
load tftp:miniroot.kmod
boot tftp:netbsd-GENERIC
Note that the change to dev_net.c to comment out the network shutdown,
suggests we need to hook the network shutdown in the the common exec code.
If the network is shutdown, it fails to reinitialise and so fails to load
the module.
will stop the countdown timer. The message now reads "Choose an option;
RETURN for default; SPACE to stop countdown." It no longer says what
the default choice actually is, because the message printed on the
following line will do that.
into the kernel. Based on a patch by jmcneill@, with many fixes and
improvements by me.
- Put MEMORY_DISK_DYNAMIC and MODULAR into the GENERIC kernels, so that
you can load miniroot.kmod from the boot blocks and boot into the
installer!
'mbr_com0' assumes the BIOS has initialised the baud rate (etc)
'mbr_com0_9600' initialises the rate to 9600
Both have the functionality from 'mbr_ext' (ie they can boot from an
extended partition).
As compiled, the io_address for the serial port is taken from BIOS data.
(this should keep tls@ happy!)
This allows easy configuration of banner text, console device and timeout
as well as allowing menus of commands to be displayed. If /boot.cfg
is not present, then the existing behaviour does not change.
The sections in the boot loader source are surrounded by #ifdef SMALL
allowing this functionality to be removed if space is at a premium.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
identify sockaddr_dl abuse that remains in the kernel, especially
the potential for overwriting memory past the end of a sockaddr_dl
with, e.g., memcpy(LLADDR(), ...).
Use sockaddr_dl_setaddr() in a few places.
(the relevant changes haven't been done though).
Call built binary bootxx_fat16 for consistency.
Use 'push %cs' to push a zero value in places where we had relied on %bx
being zero from much higher up the code.
into the first sector of a FAT16 filesystem and will load 'boot' (and hence)
the netbsd kernel from it.
Unlike bootxx_msdosfs this doesn't need the filesystem to have 8k of 'reserved'
sectors, and may well work on non-512 byte media (as yet untested).
Probably it ought to come from some generic .h file, but I've no idea
which - nor if any existing define has the same effect.
In any case this saves oodles of bytes in bootxx_msdos.
