f41c619d3d Pop the return address off the stack before making a V86_CALLF call; 
this allows us to implement what look like C function calls from user
space "directly" to v86 mode code.  (Used for calling the PnP BIOS)

d8ef941c2f - Enable PnP and ISA PnP code. 
- Use the ISA PnP enumerator.
 - Use the new linker set code, throw out the gensetdefs stuff.
 - Produce an intermediate loader image that has symbols stripped, to aid
 - in debugging.
 - Supply ISA port access functions required for ISA PnP

c90625d230 Don't depend on being part of the kernel tree. If we are, use the kernel's 
<machine> includes rather than the system's.

1a8efde980 Make serial port, data format, and bps configurable. 1998-10-20 20:20:48 +00:00

4e108bf052 Make configurable (a) whether to use int 0x13 extensions; (b) timeout 
value.  Ignore failure to update mbr sector.  Disable interrupts while
using extended registers.  Default to F1 not F2.

ae99ddc79e Fix some glitches in the input routine: 
Don't display a \b if not acting on it.
Don't process binary zero chars (which result from pressing function
keys, etc. on the PC).

918ddbed16 Having probed the keyboard, turn off the -P flag. 1998-10-17 10:35:15 +00:00
Robert Nordier
93d51dcaf9 Treat all options as toggles (ie. -c -c is the same no -c). Since 
the boot.config settings are persistent, this seems to provide a
useful override capability, and should break only on broken
boot.config's.

Output a cosmetic newline if booting with no input.

3044a22097 biosboot compatibility fix: 
If we have a boot.config command, display it.
 1998-10-17 09:16:01 +00:00
Robert Nordier
7fa25d805a biosboot compatibility fix: 
Read boot.help before parsing boot.config.  We were parsing
boot.config first, which could result in boot.help being read
from a different location (or not found), which would probably
just cause surprise, without being useful.

eb9022e791 Try and get the sys/* and machine/* includes via relative paths. This 
saves having to do a 'make includes' after touching any header file for
the boot code.

2a26e9ea83 Align to sizeof(long) rather than sizeof(int32_t). It needs to be 
long because this code is shared with the alpha.  I hope the alpha can
read 32 bit ints at 32 bit alignment (vs. 64 bit alignment).

36e85d353d Use rather than for linking. This allows the new rather 
than stale version of libstand.a to be found.

After this change, the new boot code is apparently building correctly
in a make world.

7d9cbdec8f Only call vidc_init() once (unless forced). 
Cosmetic change to the init-time character eater (like, make it increment
the index counter - if there's a problem, it would sit there in an infinite
loop instead of only running 10 times).
 1998-10-11 10:07:52 +00:00

a1c1935fa8 Fix comconsole mode. The int 0x14 read and status commands were reversed. 
Also, make sure we set %dx each time around otherwise the commands
suddenly start trying to work on things like com92 instead of com1.
Make sure comc_init() is only run once.
Cosmetic change to init-time character eater.

91284f875f Turn off the new /sys/boot stuff (except boot0) unless OBJFORMAT 
is elf.  (The BTX client must be ELF, though it is packaged as a.out
for compatibility.)

7deb2dabef Attempt to at least align MODINFO_* blocks. IMHO, decoding this stuff 
should be MD code since one day we'll have to recover pages from deleted
preload data.  MI code can't be expected to know how to deal with pmap
internals, assuming it gets done via pmap that is. :-)

1d59e49683 Turn symbol table info passing back on, although it's probably not 
particularly useful in this form.  KLD can deal with it much better.
setenv kernelname moved earlier.
 1998-10-09 23:22:30 +00:00

f62f10b275 Remove kernelname setenv, the common code does it. 
Use the metadata for symtab pointers, mainly to keep it common with
elf_freebsd.c.

cab57be9ae Remove some debugging code. 
Do a much better job of DWIM with partial device specifications.
Fix the module metadata build process, which was completely broken.
Use a larger read buffer when copying large objects in; this
improves performance marginally and will avoid flushning any small caches
we might choose to implement.

0f7d15efd8 - Drain the keyboard buffer when initialising.

afcd516b82 bootinfo.c 
Strip any device name information from the kernel name
	before passing it in.

biosdisk.c
	Be more strict about matching device names to slice entries.
	Only allow unsliced syntax on unsliced disks.
